Hardware accelerator for CRC-32 calc on i.mx RT1176

[SpeedyGonzalesss]

Hello,

I am using i.mx RT1176 and mcuXpresso. I am using CRC-32 calc(fsl_adapter_software_crc driver) for the checking the accuracy of the data I read from the flash. But the software calculation I use takes too long. Instead, I want to calculate it in hardware. I couldn't see a driver in the datasheet, but a CRC32 calculation is used in the MPEG2 variant on the FCB side. How can I speed up this process in hardware?

Hi @SpeedyGonzalesss 

I am sorry for the delayed response.

Currently we have CAAM driver on the SDK, but it CRC acceleration is  limited , you can take a look, and see if it helps you. 

Perhaps, to get better SW performance, you could execute from DTCM/ITCM memories, as they are closed to the processor.
