I'd suggest doing a study on the benefits as well. With 1+Ghz processors, the 
advantages of doing this in hardware become less than in the old days. We did 
a study on compression hardware, and at 400Mhz is was faster to do it in 
software than with external hardware. The setup, write to hardware, read from 
hardware cycles were more than the software processing requirements.
