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.
