Fast CRC function for 8-bit microcontrollers (written in C)

by Alex Dowad, last login 974 days ago

Description
The client was another developer, who was building an embedded application, using Freescale microcontrollers. He needed a fast C function to calculate a 5-bit CRC from 26 bits of data, but was overloaded with work and didn't have time to research, design, and implement the needed function.

I researched implementation options, coded, tested, and optimized 2 versions of the function: one was faster, and the other used less FLASH memory. He chose the faster one. The client was satisfied with the quality of the finished product and the speed with which it was delivered.
