TMS320F28388D: C2000Ware addition request to the VCU library - CRC calculation on LOW and HIGH bytes only

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Hello,
the VCU (VCU-II, VCRC) libraries available in C2000Ware contains functions to accelerate CRC calculations. The problem is that it doesn't support the calculation on the data streams that have only 1 half-word valid, high byte or the low byte. This is very common in the SPI and SCI communications. To be able to use the hardware acceleration the data "packing" would be required and this is inconvenient and cycle-consuming.
We have added such functions by modifying the assembly source and recompiling the library (it was fairly easy), but it would be great if TI would add it in the next C2000Ware release.

Best regards,
Andy

Hi Andy,

valid suggestions. I will pass it on to the team and see if this can be done soon. I suppose you are not waiting on this for your project to progress ?

Thanks

Hi Aravindhan,
looking forward to see it in future C2000Ware. Our "workaround" does its job, but it would be simpler and cleaner to have it directly in the TI lib.

Regards,
Andy
