Abstract
Included in this disclosure is a circuit for reducing power consumption in a microprocessor. The circuit comprises a microprocessor, at least one full instruction decoder configured to decode a present instruction, and at least one subset instruction decoder configured to determine whether the present instruction potentially needs a register. A memory element is also included and is configured to hold data from a previous instruction. A selector is included and configured to output either the previous instruction or the decoded present instruction, based on the subset instruction decoder.
