Hi ALL,
We are involved in building a product, where in we are using TMS320F2812. And an
application of the product requires calculating a check sum of program memory of
the DSP Processor (TMS320F2812) after every certain period of time. Here we are
using DSP281x_Headers_nonBIOS.
In Code Composer Studio version 3.1 we have a provision to calculate a check sum
for on-chip flash. But we need to implement an algorithm to calculate a check
sum within our software itself such that it can continuously calculate a check
sum of program memory within specified period of time, to check the hardware and
software integrity. We want information regarding an algorithm used in Code
Composer Studio version 3.1 so that we can implement the same algorithm in our
software.
Thanks & Regards,
Sanjaykumar T.

Sanjay,
I would recommend a 32 bit CRC.
Take a look at the "CRC.pdf" file that is distributed as part of
C2oooProg (http://www.codeskin.com/c2oooProg.html).
Cheers,
