Ditto - I've recently done some embedded stuff to run on a pair of
100MHz cpu (fabricated out fpga 'gates') which gave me 197 clock
cycles for the 'worst case' processing of a byte of hdlc rx and tx
(including the bit-stuffing etc).
A program to parse the gcc .s output and count the cycles was invaluable!
