Not involved, but you posted to another. As I understand it GaAs is a nascent technology with the ability to run a great deal faster than current chips. However there are process problems that may not permit a direct fab of any Pentium on GaAs, unless a complete redesign is done. Will GaAs ever reach the densities of what we now use(CMOS) or will the moving target relegate GaAs to niches where its raw speed wins.?? RISC. The use of a small number of simple instructions(often 1 cycle) to perform more complex operations by using them to perform the complex instruction as a group of smaller ones. In theory a fast RISC can emulate many other CPU's to the point where it can be faster than the CPU it copies. Like bit slice emulations in ECL were used to make very fast emulations of CPU's in the 70's and early 80's before the transistor count went to the moon. When the RISC is 10 times as fast as the copied CPU, it is easy. As the speeds converge, the RISC advantage erodes and depending on the architecture vanishes at some point, after which you only use it for other reasons. Not being an EE, I get into deep water at times. Bill
