It's often said that microcoded machines have slower cycle times than fully hardwired machines. It's sometimes said that this is due to the access time of a mongoword of ROM. Is this true? Does anyone have a modern figure for how big a ROM can be before it's slower than (say) a five-ported register bank? -- Don D.C.Lindsay Carnegie Mellon Computer Science
