           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
