DragonBoy - Re: " If a lot of PC hardware such as Cable modem, ADSL, DSL modem, capture devices move some of the hardware chip functions to the host inorder to save cost, will they optimize it with the Katmai instruction? If they do, does this mean the same hardware will perform poorly on others?"

You are talking about doing real time Signal Processing in software - running on the host CPU.

Win Modems - Modems using minimal analog/digital hardware - have been around for a few years. Invariably, they tie up most of the CPU unless a VERY FAST CPU is available. Newer 56K "Soft Modems" have been developed and they require very fast Pentium/Pentium II processors to do the modem functions and leave enough CPU cycles to handle other duties - such as run a browser!

Now, to run FASTER I/O devices such as ADSL or Cable Modems in software - at speeds of hundreds of thousands of bits/sec (or millions even!) - that would exceed the capacity of even the fastest Pentium IIs currently available.

For the time being, dedicated hardware devices will be required to implement these functions.
