Are these external caches (sound too big to be on chip)? How much (if any) delay does a cache access cost? ---------- The caches on the Series 700 are all implemented external to the chip using standard commercially available SRAMs. There is no delay for a cache access; so long as the cache is hit, instructions execute one per clock cycle. --Linley Gwennap Hewlett-Packard
