Abstract

A microprocessor includes compressed and uncompressed microcode memory storages, having N-bit wide and M-bit wide addressable words, respectively, where N<M. The microprocessor also includes a fetch unit, an instruction translator, and an execution stage. When the instruction translator receives an architectural instruction, it writes information identifying source and destination registers specified by the architectural instruction to an indirection register. It also issues one or more fetch addresses to retrieve a sequence of one or more microcode instructions from one of the uncompressed microcode memory storage and the compressed microcode memory storage to implement the architectural instruction. It merges information in the indirection register with the sequence of one or more microcode instructions to generate a sequence of one or more implementing microinstructions.
