The XPC board is our current processor board. It contains 2 ns32532's running at 30mhz. >What configurations do they come in - more specifically, what >is the largest number of processors they support? Currently from 2 - 20 processors. >What cache coherence scheme is used? (If possible, be more >specific than "snooping caches") On-chip the 532 has 1k data and 512 byte instruction caches. They are both write-through. Externally to each 532 on the processor card is a 256k ownership-based write-back cache. >Has any significant improvements been made to the Nanobus? >(Last I heard, it had 80ns cycle time and was a split-transaction >bus...) The Nanobus has always been and still is an 80ns, 100mb/sec pended bus. >Where is a good place to read about technical announcements for >companies like Encore? Got me.
