TMS570LS CRC - DMA

Normand Barriere

Other Parts Discussed in Thread: TMS570LS20216

Hello,

Is it possible to use a DMA to transfer a block of data while at the same time it calculates the CRC (CRC64 internal to TMS570). When the CRC is calculated appends the result at the end of the frame to be transfered automatically ?

I've been told that it is possible from a TI rep, but after reading the chapters in the TRM, I do not have a clue how to do that. Can someone provide me an example, again if this is possible ?

Thanks

Regards,

Normand
