Power estimation of a microprocessor based on power consumption of memory

摘要

A power estimator calculates the total power consumption of a microprocessor having a CPU 5, a main memory 1 and a plurality of cache memories 2, 3 and 4 based on an assembler description of a program and calculates power consumption values when an instruction to be executed by the CPU 5 is read from a main memory 1 and when an instruction is read from the cache memories 2, 3 and 4, determines whether the instruction to be executed is read from a memory and then calculates the total power consumption for the microprocessor by using power consumption values for the memories based on the result and the power consumption value obtained for each memory.
