Their 80960 (aka p7), which is targetted for embedded applications, is very interesting. It has good performance, but has a 4 deep register cache (registers map into the stack frame) and, more significantly, the hardware can schedule tasks for you. (Interestingly, but perhaps not surprisingly, I have not seen one trade rag mention the HW scheduling. About 1.5 years ago I benchmarked Ada on the chip and worked on a debug monitor for it, and I think that feature is very significant). Also, I think they are offering versions with fault tolerant support (last I heard it was QMR, not TMR, unfortunately). Of course, this chip will live in niche applications that most of us never see. -- Dave Bakken bakken@arizona.edu uunet!arizona!bakken "The fact that I'm paranoid doesn't prove everyone's *not* out to get me"
