Abstract: A microprocessor includes a logic circuit. A selection device is coupled to the logic circuit, and the selection device procides switching of on/off states of the logic circuit based on a stored logical value. A program instruction is included which sets the stored logical value control the on/o ff states of the logic circuit based on anticipated usage of the logical circui t in accordance with an instruction sequence of the microprocessor.

Abstract: A processor for processing a first instruction form and a second instruction form of an instruction set comprises execution units (301-305) connected to an instruction fetch unit (322) for the first instruction form and a sequencer (325) for the second instruction form. The processor comprises a decode unit (323) for decoding instructions of the first instruction form into control signals for the execution units (301-305), and buffers (306-310), proximate to the execution units (301-305), for storing predecoded instructions of the second instruction form.
