MICROPROCESSOR AND INFORMATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a microprocessor capable of reducing power consumption and of increasing speed.

SOLUTION: This microprocessor has: a detection means 1413 for detecting an instruction for operating respective calculation circuits in advance; and means 1435 and 1436 for activating one or more of the calculating circuits corresponding to the instruction detected by the detection means before calculation execution, and for inactivating the activated calculation circuit(s) after calculation termination. The microprocessor reads instructions of a quantity of (n) (n≥2) at the same time to decode them and executes calculation by using (n) pieces of the calculation circuits at the same time.
