Performance and the i860 microprocessor
M. Atkins · IEEE Micro · 1991
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.>
