Hello all,

Right now I am calculating crc with the assembly function given in control suite.

can i calculate crc with VCU directly using C?

Is it necessary to use a c-callable assembly function for calculating crc from vcu?

Shailesh,

No, the VCU is supported in assembly only.

Yes.

This would modify registers used by the codegen without it's knowledge. I do not recommend it.

Shailesh,

Try using the VCU library in the controlSUITE libs directory. There are pre-written C callable assembly functions that will do exactly what you want to do. Look in this directory:

C:\ti\controlSUITE\libs\dsp\VCU\v110
