HyperSPARC <processor> The successor to the {SuperSPARC} processor, based on the {SPARC} {ISA}. The HyperSPARC has smaller {caches} than the {SuperSPARC}: 8kb on-chip and 256kb off-chip (compared with 36kb and 1Mb). The HyperSPARC's {memory management} is optimised for more efficient out-of-cache addressing which means quicker access to external (slower, cheaper) memory. (1994-11-23)
