Operate the module only at or below Pollution Degree 2. Pollution is
foreign matter in a solid, liquid, or gaseous state that can reduce dielectric
strength or surface resistivity. The following is a description of pollution
degrees:
•
Pollution Degree 1 means no pollution or only dry, nonconductive
pollution occurs. The pollution has no influence.
•
Pollution Degree 2 means that only nonconductive pollution occurs in
most cases. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
•
Pollution Degree 3 means that conductive pollution occurs, or dry,
nonconductive pollution occurs that becomes conductive due to
condensation.
You must insulate signal connections for the maximum voltage for which
the module is rated. Do not exceed the maximum ratings for the module.
Do not install wiring while the module is live with electrical signals. Do not
remove or add connector blocks when power is connected to the system.
Avoid contact between your body and the connector block signal when hot
swapping modules. Remove power from signal lines before connecting
them to or disconnecting them from the module.
Operate the module at or below the measurement category1 marked on the
hardware label. Measurement circuits are subjected to working voltages2
and transient stresses (overvoltage) from the circuit to which they are
connected during measurement or test. Measurement categories establish
standard impulse withstand voltage levels that commonly occur in
electrical distribution systems. The following is a description of
measurement categories:
•
Measurement Category I is for measurements performed on circuits
not directly connected to the electrical distribution system referred
to as MAINS3 voltage. This category is for measurements of
voltages from specially protected secondary circuits. Such voltage

NI SPEEDY-33 Functional Description and Interface
DSP
The digital signal processor on the NI SPEEDY-33 is a powerful
floating-point, flexible, and easy-to-use processor designed by Texas
Instruments.
The VC33 DSP is capable of high performance mathematical operations.
It is a 32-bit, floating-point processor manufactured in 0.18 μm
four-level-metal CMOS (TImeline™) technology, and is part of the
SM320C3x™ generation of DSPs from Texas Instruments.
The VC33 DSP internal busing and special digital signal processing
instruction set have the speed and flexibility to execute up to 150 million
floating-point operations per second (MFLOPS). The VC33 DSP optimizes
speed by implementing functions in hardware that other processors
implement through software or microcode. This hardware-intensive
approach provides performance previously unavailable on a single chip.
Note Although this DSP is capable of 75 MIPS, 150 MFLOPS, the crystal driving the
DSP on the NI SPEEDY-33 is slightly slower than what would be required to achieve this
maximum speed, namely 14.7456 MHz as opposed to the maximum 15 MHz. This allows
for specific desirable sample rates to be achieved for the A/D and D/A hardware described
in the Stereo A/D, D/A (Analog Input, Analog Output) section. Refer to the Appendix A,
Specifications, for information about DSP speed.
The VC33 DSP can perform parallel multiply and ALU operations on
integer or floating-point data in a single cycle. Each processor possesses a
general-purpose register file, a program cache, dedicated ARAUs, internal
dual-access memories, one DMA channel supporting concurrent I/O, and a
short machine-cycle time, resulting in a high-performance, easy-to-use
device.
Typical signal processing applications are enhanced by the large address
space, multiprocessor interface, internally- and externally-generated wait
states, one external interface port, two timers, one serial port, and a
multiple-interrupt structure. The VC33 DSP supports a wide variety of
system applications from host processor to dedicated coprocessor.
High-level language support is easily implemented through a register-based
architecture, large address space, powerful addressing modes, flexible
instruction set, and well-supported floating-point arithmetic.

NI SPEEDY-33 Functional Description and Interface
Memory
There are two types of available memory on the NI SPEEDY-33, on-chip
memory and flash memory.
On-Chip Memory
The DSP uses on-chip memory for algorithms because of its fast speed.
There are 136 KB of on-chip RAM that the DSP can access with zero wait
states. This memory is used for both program and data space.
Flash Memory
The NI SPEEDY-33 includes flash memory that allows the device to be
programmed and run in standalone mode without connection to a PC. This
is essential for producing actual products or self-standing prototypes. Refer
to enable flash memory boot up for standalone mode.
The flash memory is byte-wide and organized as 512 K × 8, with the DSP
mapping it to a 512 K × 32 (2,048 KB) area, only able to read the lowest
byte (upper 24 bits are not read by or written to the DSP). Refer to the Flash
Write Enable Jumper section for information on jumper configurations for
enabling or disabling flash memory write protection.
Ports
For a diagram of port locations on the NI SPEEDY-33, refer to Figure 2-1.
PC USB Port
with a standard USB cable. The NI SPEEDY-33 functions as a full-speed
USB device when connected to the PC host. The PC USB port is a Type B
USB port (peripheral USB port) and conforms to USB Specification 1.1.
When the NI SPEEDY-33 is connected to the PC, the USB port supplies
power to the device, eliminating the need for the power port (J10), as
described in the Power Port section. When power is supplied to the device,
the power LED lights.

Chapter 2
NI SPEEDY-33 Functional Description and Interface
Power Port
Caution Do not connect the power source to the power port while the NI SPEEDY-33
device is connected to the PC.
The power port (J10) can supply the NI SPEEDY-33 with external power
when operating the device in standalone mode, without being connected to
the PC through USB. When power is supplied to the device, the power LED
lights.
The input voltage must be 9 VDC, at 500 mA, with the outside contact
being ground and inner contact being positive VDC. An appropriate
2.5 mm jack can be used in conjunction with a 9 V battery (pack) to
optionally supply power for battery-powered applications. Refer to
Appendix A, Specifications, for complete power supply specifications.
Audio Stereo Input Port
Audio input can be connected to the audio stereo input port (U11).
Caution Ensure that line level audio signals are not connected to the audio input when the
NI SPEEDY-33 is configured for microphone level. It is possible to damage the audio input
circuitry by overdriving the input.
If an external microphone is used, it should be capable of operating with a
standard stereo jack; not all microphones will work in this fashion. Many
PC microphones will not work because they require a DC voltage to be
driven on one of the inputs. Traditional mono microphones generally work
fine.
It is important to ensure that the audio input level jumpers (J1, J2) setting
is configured appropriately for microphone level or line level, depending
upon the audio source connected to this port. Refer to the Audio Input Level
Jumpers section for more information.
Note The onboard microphones are disconnected by mechanical disconnect when an
audio source is connected to the audio stereo input port.
Audio Stereo Output Port
The audio stereo output port (U14) can be connected to a set of stereo
amplified speakers. Typical amplified speakers used for PC sound should
provide good output. You also can plug external headsets to this port,
although there is no hardware control over the output gain or signal level.

Onboard Microphones
Two onboard microphones (U2 and U5) can be used in applications
requiring audio input or involving audio signal phase difference
measurements. When the microphones are used, the input gain level of
each microphone should be set to the microphone level setting described
in the Audio Input Level Jumpers section.
NI SPEEDY-33 is configured for microphone level. It is possible to damage the audio input
circuitry by overdriving the input.
The onboard microphones are directly connected to the audio input
conditioning circuitry, unless an external microphone is connected at
the stereo input port (U11), as described in the Audio Input Level Jumpers
section. If an external microphone is connected, the onboard microphones
are disconnected from the input circuitry by mechanical disconnect.
Eight memory-mapped LEDs are located on the NI SPEEDY-33 for
general-purpose output. The LEDs are enabled by writing a 1 to the
appropriate bit of the LED port. The LED output state is echoed on pins on
the simple expansion digital I/O connector (J11), as described in the Simple
Expansion Digital I/O Connector section.
Switch Input Port
There are eight memory-mapped general-purpose switch inputs on the
NI SPEEDY-33. These switch inputs are accessed by the DSP through
reading the appropriate bit of the switch input port. The switch inputs are
connected in parallel to pins on the simple expansion digital I/O connector
(J11). All switches should be in the OFF (open) position when connecting
the expansion digital I/O connector, as described in the Simple Expansion
Digital I/O Connector section.

for up to 48 kHz dual-channel sampling on the input signal. Software
components are included in the LabVIEW DSP Module to allow 8 kHz,
18 kHz, 24 kHz, 36 kHz, and 48 kHz sample rates to be used in
applications.
Refer to the Audio Input Level Jumpers section for information on jumper
settings that configure the amount of gain, from the onboard or external
microphones, applied to the input audio signals.
I/O Connectors

external hardware. The header includes power, ground, eight digital inputs,
and eight digital outputs under DSP control.
The eight input bits are co-mapped to the switch input port. The
eight output bits are co-mapped to the digital output port LEDs, as
described in the Digital Output Port LEDs section.
If the input bits on this connector will be used by an external piece of
hardware, the switch input port—described in the Switch Input Port
section—must have all the switches set in the OFF (open) position
(all switches up, away from device). An ON (closed) switch position
(switch down, towards the device) will effectively short that specific input
bit to ground. Switch 1 correlates to IN1 on the connector, switch 2
correlates to IN2, and so on. The connector pinout is shown in Figure 2-4.

Jumpers
Audio Input Level Jumpers
The audio input level jumpers (J1, J2) control the amount of gain applied
to the input audio signals.
The microphone level setting has the highest gain for the onboard
microphones (U2, U5), the line level setting has less gain and is appropriate
and so on).
These settings will affect the gain of the external audio source and should
be left in the line level setting if an external microphone or audio source
is used at audio stereo input port (U10), described in the Stereo A/D, D/A
(Analog Input, Analog Output) section. Table 2-2 shows the possible audio
input level settings.
Caution Ensure that line level audio signals are not connected to the audio input when the
NI SPEEDY-33 is configured in the microphone level setting. It is possible to damage the
audio input circuitry by overdriving the input.
