RTL - No Change |
|
Applications - Added the "application" directory to the "sw" directory. The |
first application code added is the SKIPJACK encrypt/decrypt function. This |
algorithm works on a 64 bit block of data and uses an 80 bit key. See the |
"sw/applications/skipjack/README.txt" file for more information. |
|
Testbench - To aid in software development a simple debug module was added to |
the testbench. The debugger loads watchpoint addresses stored in RAM after |
the first RAM initialization. The debugger generates trigger signals that |
can be watched in the waveform viewer and captures a copy of the CPU |
registers at each trigger event. The watch point addresses are captured by |
the assembler and stored in RAM addresses reserved for the test bench. |
There are enable registers in the testbench that can enable or disable any |
of the eight individual watchpoints under testbench control. |
|
Doc - Made corrections to some of the example code in the detailed instruction |
descriptions. |
