CRC-32 for .net core. Is using Sse42 for CRC-32C if it is available
Benchmarks
| Method | Mean | Error | StdDev |
|---|---|---|---|
| Table | 24.985 us | 0.4861 us | 0.4992 us |
| Sse42 | 9.142 us | 0.1219 us | 0.1140 us |
| Force | 45.424 us | 0.9008 us | 1.5538 us |
Table is using the conventional computation with a lookup table
Sse42 is the accelerated computation using Sse42 intrinsics. Note that only CRC-32C is supported ( polynomial = 0x82F63B78 )
Force is the fastest implementation I could find for .NET Core. The repository is here force-net/Crc32.NET, also some code for table computation derives from there.
