Performance and the i860 microprocessor

摘要

The internal design of the i860 CPU, which exploits pipelining and parallelism more than previous microprocessors, is described. The i860 uses RISC concepts and memory-performance optimizations in several novel ways. Other innovations include simultaneous floating-point operations similar to digital signal processing, a two-instruction-per-clock mode, fast floating-point pipelines graphics instructions, and high-bandwidth registers and caches on-chip. These features make it one of the fastest single-chip processors available.
