About This Guide  
Introduction  
This user guide contains information on how to integrate the stand-alone, prebuilt,  
MicroBlaze Microcontroller reference design into an FPGA. Although this design is  
targeted initially for the Xilinx Spartan-3 Starter Kit Board, the design may be modified  
readily for any Xilinx or third party platform.  
This guide is an aid in getting started and learning how to use the Xilinx Embedded  
Development Kit (EDK) tools. It does this through examples, which show how multiple  
software images can be run on a defined soft Microcontroller hardware configuration. This  
guide show how an FPGA with a soft processor can be used the same way an engineer  
would select an off the shelf microcontroller. This guide will provide examples of a  
number of different microcontroller configurations from which an engineer can choose.  
The soft microcontroller features and peripherals in the FPGA may be used without  
modification, or may be modified and customized using the Xilinx EDK Platform Studio  
tools. This guide will cover the flow where multiple software images are load on an  
unmodified hardware configuration.  
The MicroBaze Microcontroller is an integrated solution intended for implementation of  
an embedded controller in FPGA by a user without extensive knowledge of the Xilinx  
Embedded Development Kit (EDK) and the Xilinx Platform Studio (XPS). The solution  
offered in this document is a minimal implementation that can be expanded easily to  
include other peripherals and application software for different usage.  
All the necessary documentation, references, HDL code, sample codes, software drivers  
and application software are included in the tools or provided with this design.

Microcontroller Reference Design  
Overview  
Introduction  
When selecting an embedded microcontroller, typically an engineer will list the required  
features and then select a stand alone, off the shelf microcontroller or processor that has  
those features. In most cases there are additional features or peripherals that are not need,  
but are included non-the less. When using a Soft Processor in an FPGA an engineer has an  
opportunity to select from pre-created microcontroller hardware images, or modify and  
customize the features and peripherals.  
This guide is provided as an aid in getting started and learning how to use the Xilinx  
Embedded Development Kit (EDK) tools. It does this through examples, which show how  
multiple software images can run on a defined soft microcontroller hardware  
configuration. This guide show how an FPGA with a soft processor can be used the same  
way an engineer would select an off the shelf microcontroller. This guide will provide  
examples of a number of different microcontroller configurations from which an engineer  
can choose. The soft microcontroller features and peripherals in the FPGA may be used  
without modification, or may be modified and customized using the Xilinx EDK Platform  
Studio tools. This guide will cover the flow where multiple software images are loaded on  
an unmodified hardware configuration.

Done.  
Downloading Design Files to the FPGA  
The following two sections illustrate two methods of downloading a Software Application  
into the FPGA. The first method is when the Software Application can be incorporated into  
the FPGA bitstream. The second method illustrates loading a selected application into the  
FPGA using the GDB debugger for software development and debugging.  
Selecting a Software Application to Run When the FPGA is Configured  
In this step the Software Application that will be loaded when the FPGA is initially loaded  
with a new bitstream will be selected. Please select the XPS Software Application tab.  
There are 3 options that can be selected when choosing the Software Application. This first  
example will show how a Software Application can be initially added to the FPGA  
bitstream. This will configure the MicroBlaze Microcontroller program and Data memory  
with the software application already pre-loaded. This means that as soon as the FPGA has  
been successfully configured, the MicroBlaze Microcontroller Software Application will  
already be running on the MicroBlaze Microcontroller Hardware Application.  
In this case, although multiple software applications could overlap in the Bram, only one  
software application can be selected at one time. To select the desired application, perform  
the following steps:  
1. Select the Application tab the XPS window.  
2. Right click on Project: Calculator_App.  
3. Set “Mark to Initialize BRAMs”. The Project: Calculator_App will have a small green  
arrow appear to the left of the text.  
4. Confirm that “Mark to Initialize BRAMs” is not checked for the other projects and  
default applications. The Graphic to the left of each other application should appear as  
a green arrow with a red ‘X’ over it. Verify that this is the case for  
‘microblaze_0_bootloop’, ‘microblaze_0_xmdstub’, and ‘Project: TestApp’. If any are  
set, please Right click and confirm that “Mark to Initialize BRAMs” is not checked. If  
checked, click to deselect it. The green arrow should then appear with a red “X”.

Loading the “Calculator_App” Software Application  
To configure the hardware system and to load the software application into the Spartan-3  
Evaluation Board using the Digilent JTAG3 cable, perform the following steps:  
1. Connect the Digilent JTAG3 cable to the J7 header on the Spartan-3 Evaluation Board  
and connect the other end to the parallel port of the PC. If using the Parallel Cable IV,  
make sure that the ‘status’ light is lit on the cable.  
2. Connect the Serial cable to J2 on the Spartan-3 Evaluation Board and to the serial port  
of the PC. On the PC, using hyperterminal, make certain that the bit rate is set for 57600  
bps on the serial port.  
3. Turn on the power on to the Spartan-3 Evaluation Board.  
4. In XPS, to make sure that the ELF file is up to date, use Tools>Update Bitstream”.  
There may be a warning “Processor microblaze_0 has XMDSTUB-mode application,  
but xmdstub.elf is not marked for download, do you want to continue?” Click ‘YES’  
5. In XPS, select “Tools>Download” to download the new bitstream into the FPGA. The  
xmd-stub warning will appear again. Please click ‘YES’.  
Note: Close all other XMD and GDB windows prior to downloading a configuration  
bits.

Selecting a Software Application to be Loaded with a BOOT Loader after the FPGA is  
The Calculator_App is a simple 3 function calculator. The 3 right most push button  
switches are Add (BTN0), Sub (BTN1), Mult (BTN2). The left most push button switch  
(BTN3) is a program reset, which will clear the calculator program. If the reset is pushed at  
this time, then the FPGA will need to be re-loaded.  
The eight toggle switches directly under the 7-Segment display are divided into two 4 bit  
words. When the Add, Sub, or Mult push button switches are pushed, the selected  
calculator operation will be performed on the value of the toggle switches. If the toggle  
switches are set to:  
Sw7=off, Sw6=off, Sw5=off, Sw4=off, Sw3=off, Sw2=off, Sw1=off, Sw0=off  
Where Word 1 is 0 and Word 0 is 0  
Add: 0+0=0  
Sub: 0-0=0  
Mult 0*0=0  
If the toggle switches are set to:  
Sw7=off, Sw6=off, Sw5=off, Sw4=ON, Sw3=off, Sw2=off, Sw1=ON, Sw0=ON  
Where Word 1 is 1 and Word 0 is 3  
Add: 3+1=4  
Sub: 3-1=2  
Mult 3*1=3  
Each time one of the Push Button switches is pressed, the result should be displayed in  
‘decimal’ on the 7-Seg display, and it will also be sent to the hyperterminal through the  
UART. The hyperterminal display should show:  
3 + 1 = 4  
Push button to start math operation...  
3 - 1 = 2  
Push button to start math operation...  
3 * 1 = 3

The next section will show how to load this same program after the FPGA has been  
configured.  
Selecting a Software Application to be Loaded with a BOOT  
Loader after the FPGA is Configured and the Processor is Running  
This step will show an example of how a Hardware Application can be initially loaded  
with a “Stub” program. This will configure the MicroBlaze Microcontroller where it is  
waiting to be loaded with the actual Software Application.
