what are the numbers? Are you accounting for the overhead in accessing the 
hardware? the impact of the stop-and-wait requirements for hardware 
processing? What about bus availability in a heavily utilized router? You are 
going to double the bus requirement.

Most people take a rather trivial approach to such evaluations, and i suppose 
im concerned about anyone who thinks that hardware is "always faster" than 
software, because that argument is blatently wrong. a 33Mhz ASIC will not 
always be faster than the host, particularly with transfer and setup 
requirements. It has to be 3-5 times faster than the host just to break even.
