Abstract:
PCT No. PCT/JP95/00356 Sec. 371 Date Sep. 3, 1997 Sec. 102(e) Date Sep. 3, 1997 PCT Filed Mar. 6, 1995 PCT Pub. No. WO96/27833 PCT Pub. Date Sep. 12, 1996An information processor is capable of eliminating register conflict in short and long latency processes and for attaining high-speed pipeline processing through efficient use of registers. The scale of the necessary hardware is reduced by the processor using a register conflict detector and a scoreboard. The register conflict detector detects register conflict over a period of short latency processing, and the scoreboard checks for register conflict beyond the short latency process period and into a period of long latency processing. The processor controls the issue of instructions based on the detected register conflict status.
