i860

   Also found in: Wikipedia 0.01 sec.

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.

(processor)i860 - A 32/64-bit superscalar RISC microprocessor from 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 mode which only uses eight bits of the data bus to allow the use of a small boot ROM. It has a 32-bit wide instruction cache and a separate 64-bit wide data cache. It uses register scoreboarding and register bypassing. The clock rate is 33 MHz with a clock-doubled version available.

This approach makes it possible to use the tools employed by Microway in the past to drive vector processors like the i860, while at the same time enabling historic vectorization tools like VAST, that can automatically convert serial Fortran codes into Fortran programs that utilize vector FPGA primitives.
