Abstract
A decoder circuit decodes a macro-instruction by selecting an alias encoding from the data size encodings in the micro-instruction. The decoder comprises a type detector to determine the macro-instruction type, an extraction circuit for extracting the encoding of the non-multimedia enhancement instructions, a matching circuit for matching the macro-opcode with the opcodes of the multimedia enhancement instructions, and a selecting circuit to select the alias encoding for the micro-instruction. The decoder expands the scope of the data size field to accommodate additional multimedia enhancement instructions without significant change in hardware.
