• 836e2af92   crc32: major optimization ... Browse Code »

  Precompute more crc32 values(0xcc00, 0xcc0000 and 0xcc000000) into tables.
  This increases the table size from 1KB to 4KB but the performance benfit
  makes it worth it:

  28% faster on MPC8321, 266 MHz
  2x faster on Core 2 Duo, 3.1GHz
