i860

(processor)A 32/64-bit superscalar RISC microprocessorfrom Intel, released in 1989. Originally codenamed "N10".It has a 32-bit integer ALU and a 64-bit floating-point unit. It has a 64-bit data bus with an initialisation modewhich only uses eight bits of the data bus to allow the use ofa small boot ROM. It has a 32-bit wide instruction cacheand a separate 64-bit wide data cache. It uses register scoreboarding and register bypassing. The clock rate is33 MHz with a clock-doubled version available.

i860

A 32-bit RISC-based microprocessor from Intel that included a 64-bit floating point unit (FPU) and 64-bit buses. Introduced in 1988, it had limited use in Unix workstations for 3D graphics applications and also in Intel's iPSC/860 supercomputer. Both the i860 and i960 were replaced with the StrongARM chips acquired from Digital Equipment. See i960.
