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,

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,
Beat
