So the other day, I tried gauging the performance of SHA256 hardware acceleration on TM4C running at 16 MHz.
Here are the results (Time taken to hash a single block):
Software SHA256: 1.216 milliseconds or 1216 microseconds.
SHA256 using Hardware Acceleration: 28 microseconds (4200% faster)
For performing SHA256 in software I used this code: http://www.spale.com/download/scrypt/scrypt1.0
More details and test code on my blog post here.

Just wanted to share it with everyone since the CCM0 module for SHA256 has not been covered in many forum posts here.
