【正文】 0 workstation and Macintosh puters, is a RISC microprocessor. ? Intel39。s Pentium microprocessors are CISC microprocessors. Combine RISC and CISC ? RISC takes each of the longer, more plex instructions from a CISC design and reduces it to multiple instructions that are shorter and faster to process.

The original RISC prototype puter, called the 801 Miniputer, was built at IBM39。s Research Division in 1980 the result of a project that began in the 197039。s. ? 1950s IBM instituted a research program ? 1964 Release of System/360 ? Mid1970s improved measurement tools demonstrated on CISC ? 1975 801 project initiated at IBM’s Watson Research Center ? 1979 32bit RISC microprocessor (801) developed led by Joel Birnbaum ? 1984 MIPS developed at Stanford, as well as projects done at Berkeley ? 1988 RISC processors had taken over highend of the workstation market ?
