Use of 64-bit machine code [*], particularly instructions that make use of= =20 64-bit native[**] registers[***]. * Defining this is more difficult, since that does not mean instruction=20 requiring 64-bits to represent as many architectures have variable length=20 instructions. ** Native is a difficult term to define, but I'm explicitly excluding the=20 floating-point registers that have been 64-bit or 80-bit from my vague noti= on=20 of native *** I guess this makes the Cell processor 128-bit?
