I'm interested in GaAs, although I don't much about Prisma. If the failure was technology related, was that due to the use of parts from Gigabit - high speed, but also high power and only MSI density (not to mention the fact the Gigabit is in financial trouble)? The leading start-up in GaAs seems to be Vitesse, which trades off some speed for lower power and higher density (currently, around 15,000 gates). On a related subject, DARPA has funded a number of GaAs RISC chips, which have been reported in various conferences and acedemic publications. This research has, at least so far, resulted in no commercial spin-offs. Is GaAs just not up to it? Is the technology too immature still? It certainly appears to me that the current Vitesse technology would do fine for a Risc chip set. It appears from recent EE times articles that at least Convex and Solbourne think select use of GaAs is worthwhile. Any comments, netland? /Nick Michell michell@cs.utah.edu
