A 32/64-bit superscalarRISCmicroprocessor 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. (1998-03-28)
