Sadly this is only an ARM9TDMI core and so misses out on the
(substantial) benefits that the extra instructions in the 9EJ and
11J architectures confer on such routines. Packed arithmetic
makes a huge difference to CRC16.
I've been meaning to write some ARM SIMD routines for
checksumming; if I can get permission to release them, I'll let you
know. (My employer is a bit paranoid...)
