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! David -- David Laight: [email protected]
