Super Fast CRC Algorithm

Friday, September 4, 2015

Take a look at the details here: https://software.intel.com/en-us/blogs/2015/09/02/whats-wrong-with-my-crc Specifically these two lines of code: Fast CRC 16 C myCrc ^= *buffer++; myCrc = (myCrc) ^ (myCrc << 5) ^ (myCrc << 8); Fast CRC 16 C# myCrc ^= (ushort)(buffer); myCrc = (ushort)((myCrc) ^ (myCrc << 5) ^ (myCrc << 8)); It looks like a very efficient CRC method, for both CPU and Memory utilization. I can't find anything wrong with it, so why isn't this kind of implementation the first hit on google? What am I missing there? Any idea is welcome.
