7 CLA-PROMCRC – CLA Program Integrity check

The CLAPROMCRC module calculates CRC-32 value of a configurable block of data in CLA program ROM. The CLAPROMCRC calculates the CRC-32 in a non-intrusive manner when the CLA is not accessing the ROM on the CLA program bus. Neither the CPU nor the CLA has the capability to compute a CRC on the CLA program ROM and this limitation is handled by the CLAPROMCRC unit. However, CLAPROMCRC cannot be used for any other memory block. The BGCRC engine has the capability to perform CRC on CLA Program ROM. Hence, in devices with BRCRC it can be used. CLAPROMCRC module can be used on devices where BGCRC support is not available.

For software support, see C2000ware: <C2000Ware>\driverlib\<device>\examples\clapromcrc.
