A computer, circuit, and computer-readable medium are disclosed. In one embodiment, the processor includes an instruction decoder unit that can decode a macro instruction into at least one micro-operation with a set of data fields. The resulting micro-operation has at least one data field that is in a compressed form. The instruction decoder unit has storage that can store the micro-operation with the compressed-form data field. The instruction decoder unit also has extraction logic that is capable of extracting the compressed-form data field into an uncompressed-form data field. After extraction, the instruction decoder unit also can send the micro-operation with the extracted uncompressed-form data field to an execution unit. The computer also includes an execution unit capable of executing the sent micro-operation.
