Abstract
A technique for providing information about the relationship between circuits and the amounts of power consumed by the respective circuits to control a heat-sensitive circuit with higher accuracy is disclosed. A decoder (6a) causes an ALU power evaluation counter (7a) to count when a control code applied thereto is not an ALU control code. The ALU power evaluation counter (7a) counts the number of control codes which do not operate an ALU (5a). A multiplier (14) multiplies the output from the ALU power evaluation counter (7a) by a predetermined number to provide the result to an adder (10). The adder (10) adds the results from multipliers (14-16) together to store the result in a total power evaluation register (11). The smaller the value stored in the total power evaluation register (11), the greater the amount of heat generated. A DRAM refresh control circuit (12) shortens a refresh cycle so that a DRAM (13) is frequently refreshed.
