Architectural features of the i860-microprocessor RISC core and on-chip caches

The Intel i860 is a one-million-transistor, high-performance RISC (reduced-instruction-set computer) microprocessor. The performance of the i860 CPU is derived using supercomputer architectural concepts such as parallel instruction execution and a 64-b architecture that provides the data and instruction bandwidth necessary to support multiple operations. The novel features of the i860 RISC integer core are explored. The on-chip cache architecture, which is optimized for large data and instruction bandwidth, is described.>
