The source code for the demo software can be installed to a directory of your choice. If you choose to
re-compile the software, you must install the Chip Support Library (CSL) available from Texas
Instruments. The precompiled image included on the disk was compiled with CSL version 10, although
newer versions of the software should also work.

Running the DSP Software
To execute the software, first connect the Blackhawk emulation pod to the Tsi620 evaluation board
connector. The 60-pin connector is not keyed, however once the Blackhawk emulator and adapter are
installed, a correctly oriented cable will have the lead pointing toward the FPGA fan.
On your PC, perform the following steps to run the DSP software:
1. Launch Code Composer Studio Setup.
2. Select “File->Import” and browse to the Tsi620EVB.ccs file found on the CD in the “DSP”
directory.
This configures CCS and the Blackhawk emulator to use the 3-core DSP mounted on the Tsi620
evaluation board.
3. Click “Save and Quit” and launch Code Composer Studio.
The “CCStudio: Parallel Debug Manager” window appears with four entries: ICEPICK_C_0,
C6400PLUS_0, C6400PLUS_1, and C6400PLUS_2. The C6400PLUS entries represent the three
cores in the TI 6487 DSP.
4. Right-click on C6400PLUS_0 and select “Connect”.
5. Double-click on C6400PLUS_0 to enter CCStudio using Core 0.
6. From the “File” menu, select “Load Program”.
7. Select the file “DSPDemo.out” located on the disc.
This programs the DSP from the precompiled file.
8. From the “Debug” menu, select “run”.
The DSP is now executing code, and waiting for interaction from the PowerPC

DSP Hardware Facilities
DSP hardware that is accessible from other devices includes L2 cache memory on each of the three
DSP cores. These memory addresses can be accessed from RapidIO using I/O transactions beginning at
offset 0x10800000 for core 0, 0x20800000 for core 1, and 0x30800000 for core 2. Each core can access
its local L2 cache as address 0x00800000.
The DSP hardware also supports RapidIO Doorbell functionality, although this is not covered by the
demo software or by this document (for more information, Texas Instruments documentation).
