I860
<processor> 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.
