Multi-CPU system and scaling method for multi-CPU system

摘要

In an asymmetric multi-CPU system in which a plurality of types of CPUs having different data processing performance and power consumption are mounted for each type, the CPU is configured so that the overall data processing performance and the maximum power consumption are different in multiple stages. A plurality of forms of combinations of types and numbers are defined, and control is performed to assign data processing to the CPU specified by the form selected from the definition information in accordance with the data processing environment. According to a data processing environment such as a data processing load, wasteful power consumption is suppressed and necessary data processing performance is easily realized.
