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.
