ABSTRACT:
A decoder that includes a micro-alias register to store information from a micro-operation for use by later micro-operations in the micro-operation flow. The decoder includes one or more XLAT PLAs that produces PLA control micro-operations ("Cuops"), a microcode sequencing unit that produces microcode Cuops, and an aliasing mechanism that extracts fields and stores them in macro-alias registers. A multiplexer is provided to select the appropriate Cuop to be stored in a Cuop register. Multiple Cuops may issue each cycle. A multiplexer is coupled to select one of the Cuops and to store predetermined fields in the micro-alias register for use by subsequent Cuops. Micro-alias data and macro-alias data can be utilized simultaneously with a Cuop to form an Auop.
