Intel 80960Hx Processor  
The Intel 80960Hx processor provides new performance levels while maintaining backward  
compatibility (pin1 and software) with the i960 CA/CF processor. This newest member of the  
family of i960 32-bit, RISC-style, embedded processors allows customers to create scalable  
designs that meet multiple price and performance points. This is accomplished by providing  
processors that may run at the bus speed or faster using Intel’s clock multiplying technology  
(see Table 1). The 80960Hx core is capable of issuing 150 million instructions per second, using a  
sophisticated instruction scheduler that allows the processor to sustain a throughput of two  
instructions every core clock, with a peak performance of three instructions per clock. The  
80960Hx-series comprises three processors, which differ in the ratio of core clock speed to external  
bus speed.

80960HA/HD/HT  
In addition to expanded clock frequency options, the 80960Hx provides essential enhancements for  
an emerging class of high-performance embedded applications. Features include a larger  
instruction cache, data cache, and data RAM than any other 80960 processor to date. It also boasts  
a 32-bit demultiplexed and pipelined burst bus, fast interrupt mechanism, guarded memory unit,  
wait state generator, dual programmable timers, ONCE and IEEE 1149.1-compliant boundary scan  
test and debug support, and new instructions.  
2.1  
The i960® Processor Family  
The i960® processor family is a 32-bit RISC architecture created by Intel to serve the needs of  
embedded applications. The embedded market includes applications as diverse as industrial  
automation, avionics, image processing, graphics and communications.  
Because all members of the i960 processor family share a common core architecture, i960  
applications are code-compatible. Each new processor in the family adds its own special set of  
functions to the core to satisfy the needs of a specific application or range of applications in the  
embedded market.  
2.2  
Key 80960Hx Features  
2.2.1  
Execution Architecture  
Independent instruction paths inside the processor allow the execution of multiple, out-of-sequence  
instructions per clock. Register and resource scoreboarding interlocks maintain the logical integrity  
of sequential instructions that are being executed in parallel. To sustain execution of multiple  
instructions in each clock cycle, the processor decodes multiple instructions in parallel and  
simultaneously issues these instructions to parallel processing units. The various processing units  
are then able to independently access instruction operands in parallel from a common register set.  
Local Register Cache integrated on-chip provides automatic register management on call/return  
instructions. Upon a call instruction, the processor allocates a set of local registers for the called  
procedure, then stores the registers for the previous procedure in the on-chip register cache. As  
additional procedures are called, the cache stores the associated registers such that the most recently  
called procedure is the first available by the next return (ret) instruction. The processor may store up  
to fifteen register sets, after which the oldest sets are stored (spilled) into external memory.  
The 80960Hx supports the 80960 architecturally-defined branch prediction mechanism. This  
allows many branches to execute with no pipeline break. With the 80960Hx’s efficient pipeline, a  
branch may take as few as zero clocks to execute. The maximum penalty for an incorrect prediction  
is two core clocks.  
2.2.2  
Pipelined, Burst Bus  
A 32-bit high performance bus controller interfaces the 80960Hx core to the external memory and  
peripherals. The Bus Control Unit features a maximum transfer rate of 160 Mbytes per second (at a  
40 MHz external bus clock frequency). A key advantage of this design is its versatility. The user  
may independently program the physical and logical attributes of system memory. Physical  
attributes include wait state profile, bus width, and parity. Logical attributes include cacheability  
and Big or Little Endian byte order. Internally programmable wait states and 16 separately  
configurable physical memory regions allow the processor to interface with a variety of memory

80960HA/HD/HT  
subsystems with minimum system complexity. To reduce the effect of wait states, the bus design is  
decoupled from the core. This lets the processor execute instructions while the bus performs  
memory accesses independently.  
The Bus Controller’s key features include:  
Demultiplexed, Burst Bus to support most efficient DRAM access modes  
Address Pipelining to reduce memory cost while maintaining performance  
32-, 16- and 8-bit modes to facilitate I/O interfacing  
Full internal wait state generation to reduce system cost  
Little and Big Endian support  
Unaligned Access support implemented in hardware  
Three-deep request queue to decouple the bus from the core  
Independent physical and logical address space characteristics  
2.2.3  
2.2.4  
On-Chip Caches and Data RAM  
As shown in Figure 1, the 80960Hx provides generous on-chip cache and storage features to  
decouple CPU execution from the external bus. The processor includes a 16 Kbyte instruction  
cache, an 8 Kbyte data cache and 2 Kbytes of Data RAM. The caches are organized as 4-way set  
associative. Stores that hit the data cache are written through to memory. The data cache performs  
write allocation on cache misses. A fifteen-set stack frame cache allows the processor to rapidly  
allocate and deallocate local registers. All of the on-chip RAM sustains a 4-word (128-bit) access  
every clock cycle.  
Priority Interrupt Controller  
The interrupt unit provides the mechanism for the low latency and high throughput interrupt  
service essential for embedded applications. A priority interrupt controller provides full  
programmability of 240 interrupt sources with a typical interrupt task switch (latency) time of 17  
core clocks. The controller supports 31 priority levels. Interrupts are prioritized and signaled within  
10 core clocks of the request. When the interrupt has a higher priority than the processor priority,  
the context switch to the interrupt routine would typically complete in another seven bus clocks.  
External agents post interrupts through the 8-bit external interrupt port. The Interrupt unit also  
handles the two internal sources from the Timers. Interrupts may be level- or edge-triggered.  
2.2.5  
Guarded Memory Unit  
The Guarded Memory Unit (GMU) provides memory protection without the address translation  
found in Memory Management Units. The GMU contains two memory protection schemes: one  
prevents illegal memory accesses, the other detects memory access violations. Both signal a fault  
to the processor. The programmable protection modes are: user read, write or execute; and  
supervisor read, write or execute.

80960HA/HD/HT  
2.2.6  
Dual Programmable Timers  
The processor provides two independent 32-bit timers, with four programmable clock rates. The  
user configures the timers through the Timer Unit registers. These registers are memory-mapped  
within the 80960Hx, addressable on 32-bit boundaries. The timers have a single-shot mode and  
auto-reload capabilities for continuous operation. Each timer has an independent interrupt request  
to the processor’s interrupt controller.  
2.2.7  
Processor Self Test  
When a system error is detected, the FAIL pin is asserted, a fail code message is driven onto the  
address bus, and the processor stops execution at the point of failure. The only way to resume  
normal operation is to perform a RESET operation. Because System Error generation may occur  
sometime after the bus confidence test and even after initialization during normal processor  
operation, the FAIL pin is HIGH (logic “1”) before the detection of a System Error.  
The processor uses only one read bus-transaction to signal the fail code message; the address of the  
bus transaction is the fail code itself. The fail code is of the form: 0xfeffffnn; bits 6 to 0 contain a  
mask recording the possible failures. Bit 7, when set to 1, indicates that the mask contains failures  
from the internal Built-In Self-Test (BIST); when 0, the mask indicates other failures.  
Ignore reserved bits 0 and 1. Also ignore bits 5 and 6 when bit 7 is clear (=0).  
The mask is shown in Table 2 and Table 3.

ADDRESS BUS carries the upper 30 bits of the physical address. A31 is the most  
significant address bit and A2 is the least significant. During a bus access, A31:2  
identify all external addresses to word (4-byte) boundaries. The byte enable  
signals indicate the selected byte in each word. During burst accesses, A3 and  
A2 increment to indicate successive addresses.

DATA BUS carries 32, 16, or 8-bit data quantities depending on bus width  
configuration. The least significant bit of the data is carried on D0 and the most  
significant on D31. The lower eight data lines (D7:0) are used when the bus is  
configured for 8-bit data. When configured for 16-bit data, D15:0 are used.

DATA PARITY carries parity information for the data bus. Each parity bit is  
assigned a group of eight data bus pins as follows:  
I/O  
DP3 generates/checks parity for D31:24  
DP2 generates/checks parity for D23:16  
DP1 generates/checks parity for D15:8  
DP0 generates/checks parity for D7:0

PCHK  
Parity information is generated for a processor write cycle and is checked for a  
processor read cycle. Parity checking and polarity are programmable. Parity  
generation/checking is only performed for the size of the data accessed.  
O
PARITY CHECK indicates the result of a parity check operation. An asserted  
PCHK indicates that the previous bus read access resulted in a parity check error.

READY, when enabled for a memory region, is asserted by the memory  
subsystem to indicate the completion of a data transfer. READY is used to  
indicate that read data on the bus is valid, or that a write transfer has completed.  
READY works in conjunction with the internal wait state generator to  
accommodate various memory speeds. READY is sampled after any  
programmed wait states:  
I

S(L)  
During each data cycle of a burst access  
During the data cycle of a non-burst access  
BURST TERMINATE, when enabled for a memory region, is asserted by the  
memory subsystem to terminate a burst access in progress. When BTERM is  
asserted, the current burst access is terminated and another address cycle  
occurs.

BURST LAST indicates the last transfer in a bus access. BLAST is asserted in  
the last data transfer of burst and non-burst accesses after the internal wait-state  
generator reaches zero. BLAST remains active as long as wait states are inserted  
through the READY pin. BLAST becomes inactive after the final data transfer in a

DT/R  
DATA TRANSMIT/RECEIVE indicates direction for data transceivers. DT/R is  
used with DEN to provide control for data transceivers connected to the data bus.  
DT/R is driven low to indicate the processor expects data (a read cycle). DT/R is  
driven high when the processor is “transmitting” data (a store cycle). DT/R only  
changes state when DEN is high.

DATA ENABLE indicates data transfer cycles during a bus access. DEN is  
asserted at the start of the first data cycle in a bus access and de-asserted at the  
end of the last data cycle. DEN remains asserted for an entire bus request, even  
when that request spans several bus accesses. For example, a ldq instruction  
starting at an unaligned quad word boundary is one bus request spanning at least  
two bus accesses. DEN remains asserted throughout all the accesses (including  
ADS states) and de-asserts when the Iqd instruction request is satisfied. DEN is  
used with DT/R to provide control for data transceivers connected to the data bus.  
DEN remains asserted for sequential reads from pipelined memory regions.

BUS LOCK indicates that an atomic read-modify-write operation is in progress.  
LOCK may be used by the memory subsystem to prevent external agents from  
accessing memory that is currently involved in an atomic operation (e.g., a  
semaphore). LOCK is asserted in the first clock of an atomic operation and de-  
asserted when BLAST is deasserted in the last bus cycle.

Description  
HOLD REQUEST signals that an external agent requests access to the  
processor’s address, data, and control buses. When HOLD is asserted, the  
processor:  
I
Completes the current bus request.  
HOLD  
S(L)  
Asserts HOLDA and floats the address, data, and control buses.  
When HOLD is deasserted, the HOLDA pin is deasserted and the processor  
reassumes control of the address, data, and control pins.  
O
HOLD ACKNOWLEDGE indicates to an external master that the processor has  
relinquished control of the bus. The processor grants HOLD requests and enters  
the HOLDA state while the RESET pin is asserted.  
H(1)  
B(0)  
R(Q)  
HOLDA  
BOFF  
HOLDA is never granted while LOCK is asserted.  
BUS BACKOFF forces the processor to immediately relinquish control of the bus  
on the next clock cycle. When READY/BTERM is enabled and:  
When BOFF is asserted, the address, data, and control buses are floated on the  
next clock cycle and the current access is aborted.  
I
S(L)  
When BOFF is deasserted, the processor resumes by regenerating the aborted  
bus access.  
See Figure 16 on page 48 for BOFF timing requirements.  
O
BUS REQUEST indicates that a bus request is pending in the bus controller.  
BREQ does not indicate whether or not the processor is stalled. See BSTALL for  
processor stall status. BREQ may be used with BSTALL to indicate to an external  
bus arbiter the processor’s bus ownership requirements.  
H(Q)  
B(Q)  
R(0)  
BREQ  
O
BUS STALL indicates that the processor has stalled pending the result of a  
request in the bus controller. When BSTALL is asserted, the processor must  
regain bus ownership to continue processing (i.e., it may no longer execute  
strictly out of on-chip cache memory).

EXTERNAL INTERRUPT pins are used to request interrupt service. These pins  
may be configured in three modes:  
Dedicated Mode: Each pin is assigned a dedicated interrupt level. Dedicated  
inputs may be programmed to be level (low or high) or edge (rising or falling)  
sensitive.  
I
XINT7:0  
A(E)  
A(L)  
Expanded Mode: All eight pins act as a vectored interrupt source. The interrupt  
pins are level sensitive in this mode.  
Mixed Mode: The XINT7:5 pins act as dedicated sources and the XINT4:0 pins  
act as the five most significant bits of a vectored source. The least significant bits  
of the vectored source are set to “010” internally.  
I
NON-MASKABLE INTERRUPT causes a non-maskable interrupt event to occur.  
NMI is the highest priority interrupt source. NMI is falling edge triggered.

CLOCK INPUT provides the time base for the 80960Hx. All internal circuitry is  
synchronized to CLKIN. All input and output timings are specified relative to  
CLKIN.  
CLKIN  
I
For the 80960HD, the 2x internal clock is derived by multiplying the CLKIN  
frequency by two. For the 80960HT, the 3x internal clock is derived by multiplying  
the CLKIN frequency by three.  
RESET forces the device into reset. RESET causes all external and internal  
signals to return to their reset state (when defined). The rising edge of RESET  
starts the processor boot sequence.  
I
RESET  
STEST  
A(L)  
I
SELF TEST, when asserted during the rising edge of RESET, causes the  
processor to execute its built in self-test.  
S(L)  
FAIL indicates a failure of the processor’s built-in self-test performed during  
initialization. FAIL is asserted immediately out of reset and toggles during self-test  
to indicate the status of individual tests. When self-test passes, FAIL is de-  
asserted and the processor branches to the user’s initialization code. When self-  
test fails, the FAIL pin asserts and the processor ceases execution.

80960HA/HD/HT  
3.3  
Package Thermal Specifications  
The 80960Hx is specified for operation when TC (case temperature) is within the range of  
0 °C to 85 °C. TC may be measured in any environment to determine whether the 80960Hx is  
within the specified operating range. Measure the case temperature at the center of the top surface,  
opposite the pins. Refer to Figure 5.  
TA (ambient temperature) is calculated from θCA (thermal resistance from case to ambient) using  
Equation 1:  
Equation 1. Calculation of Ambient Temperature (TA)  
TA = TC (P ⋅ θCA  
)
Table 12 shows the maximum TA allowable (without exceeding TC) at various airflows and  
operating frequencies (fCLKIN).  
Note that TA is greatly improved by attaching fins or a heatsink to the package. P (maximum power  
consumption) is calculated by using the typical ICC as tabulated in Section 4.6, “DC  
Specifications” on page 40 and VCC of 3.3 V.

Heat Sink Adhesives  
Intel recommends silicone-based adhesives to attach heat sinks to the PGA package. There is no  
particular recommendation concerning the PQ4 package.  
PowerQuad4 Plastic Package  
The 80960Hx family is available in an improved version of the common 208-lead SQFP plastic  
package called the PowerQuad4* (PQ4). The PQ4 package dimensions and lead pitch are identical  
to the SQFP package and the former PQ2 package, so the PQ4 fits into the same board footprint.  
The advantage of the PQ4 package is the superior thermal conductivity that allows the plastic  
version of the 80960Hx to operate with the same 0 °C to 85 °C temperature specifications as the  
more expensive ceramic PGA package.  
The PQ4 package integrates a copper heat sink within the package to dissipate heat effectively. See  
Table 14 and Table 15 for more information.  
3.6  
Stepping Register Information  
The memory-mapped register at FF008710H contains the 80960Hx Device ID. The ID is identical  
to the ID obtained from a JTAG Query. Figure 6 defines the current 80960Hx Device IDs. The  
value for device identification is compliant with the IEEE 1149.1 specification and Intel standards.  
Table 16 describes the fields of the device ID.

4.3  
Recommended Connections  
Power and ground connections must be made to multiple VCC and VSS (GND) pins. Every  
80960Hx-based circuit board should include power (VCC) and ground (VSS) planes for power  
distribution. Every VCC pin must be connected to the power plane; every VSS pin must be  
connected to the ground plane. Pins identified as “NC” —no connect pins—must not be connected  
in the system.  
Liberal decoupling capacitance should be placed near the 80960Hx. The processor may cause  
transient power surges when its output buffers transition, particularly when connected to large  
capacitive loads.  
Low inductance capacitors and interconnects are recommended for best high-frequency electrical  
performance. Inductance may be reduced by shortening the board traces between the processor and  
decoupling capacitors as much as possible. Capacitors specifically designed for PGA packages  
offer the lowest possible inductance.  
For reliable operation, always connect unused inputs to an appropriate signal level. In particular,  
any unused interrupt (XINT7:0, NMI) input should be connected to VCC through a pull-up resistor,  
as should BTERM when not used. Pull-up resistors should be in the range of 20 Kfor each pin  
tied high. When READY or HOLD are not used, the unused input should be connected to ground.  
N.C. pins must always remain unconnected.  
4.4  
VCC5 Pin Requirements (V  
)
DIFF  
In mixed-voltage systems that drive 80960Hx processor inputs in excess of 3.3 V, the VCC5 pin  
must be connected to the system’s 5 V supply. To limit current flow into the VCC5 pin, there is a  
limit to the voltage differential between the VCC5 pin and the other VCC pins. The voltage  
differential between the 80960Hx VCC5 pin and its 3.3 V VCC pins should never exceed 2.25 V.  
This limit applies to power-up, power-down, and steady-state operation. Table 21 outlines this  
requirement.  
Meeting this requirement ensures proper operation and ensures that the current draw into the VCC5  
pin does not exceed the ICC5 specification.  
When the voltage difference requirements cannot be met due to system design limitations, an  
alternate solution may be employed. As shown in Figure 7, a minimum of 100 series resistor  
may be used to limit the current into the VCC5 pin. This resistor ensures that current drawn by the  
VCC5 pin does not exceed the maximum rating for this pin.  
Figure 7. VCC5 Current-Limiting Resistor  
+5 V (±0.25 V)  
VCC5 Pin  
100 Ω  
(±5%, 0.5 W)  
This resistor is not necessary in systems that may ensure the VDIFF specification.  
In 3.3 V-only systems and systems that drive 80960Hx pins from 3.3 V logic, connect the VCC5  
pin directly to the 3.3 V VCC plane.

4.5  
VCCPLL Pin Requirements  
When the voltage on the VCCPLL power supply pin exceeds the VCC pin voltage by 0.5 V at any  
time, including the power up and power down sequences, excessive currents may permanently  
damage on-chip electrostatic discharge (ESD) protection diodes. The damage may accumulate over  
multiple episodes.  
Pragmatically, this problem only occurs when the VCCPLL and VCC pins are driven by separate  
power supplies or voltage regulators. Applications that use one power supply for VCCPLL and  
VCC are not typically at risk. Verify that your application does not allow the VCCPLL voltage to  
exceed VCC by 0.5 V.  
The VCCPL low-pass filter recommended in the Developer’s Manual does not promote this  
problem.

RESET must meet setup and hold times to the rising edge of the CLKIN.  
9. The interrupt pins are synchronized internally by the 80960Hx. They have no required setup or hold times  
for proper operation. These pins are sampled by the interrupt controller every clock and must be active for  
at least two consecutive CLKIN rising edges when asserting them asynchronously. To ensure recognition at  
a particular clock edge, the setup and hold times shown must be met.

Note: READY adds memory access time to data transfers, whether or not the  
bus access is a burst access. BTERM interrupts a bus access, whether or not  
the bus access has more data transfers pending. Either the READY signal or  
the BTERM signal terminates a bus access when the signal is asserted during  
the last (or only) data transfer of the bus access.

Figure 49. BREQ and BSTALL Operation  
CLKIN  
ADS  
BLAST  
BREQ  
BSTALL  
The processor may stall (BSTALL asserted) even with an empty bus queue (BREQ deasserted).  
Depending on the instruction stream and memory wait states, the two signals may be separated by  
several CLKIN cycles.  
Bus arbitration logic that logically ‘ANDs’ BSTALL and BREQ will not correctly grant the bus to  
the processor in all stall cases, potentially degrading processor performance.  
Do not logically ‘AND’ BSTALL and BREQ together in arbitration logic. Instead, the simplest bus  
arbitration should logically “OR” BSTALL and BREQ to determine the processor’s bus ownership  
requirements.  
More sophisticated arbitration should recognize the priority nature of these two signals. Using a  
traffic light analogy, BREQ is a ‘yellow light’ warning of a possible processor stall and BSTALL is  
a ‘red light’ indicating a stall in progress.

subsequent read access is concurrent with the last data cycle of the access. Because External Ready  
Control is disabled for Read Pipelining, the address cycle occurs during BLAST.

entails an extensive IEEE review and a formal acceptance balloting procedure  
which may change the resultant form of the language. Be aware that this process  
may extend well into 1993, and at this time the IEEE does not endorse or hold an

compliant devices. This language is under consideration by the IEEE for formal  
inclusion within a supplement to the 1149.1-1990 standard. The generation of the  
supplement entails an extensive IEEE review and a formal acceptance balloting  
procedure which may change the resultant form of the language. Be aware that this  
process may extend well into 1993, and at this time the IEEE does not endorse or
