Abstract

The invention relates the multinuclear processor electric power control unit and method. The electric power control unit comprises processor with at least two nucleuses, operating voltage and electric control part. The electric power control method comprises the following steps: basing the nucleus usage content, judging whether adjusting operating voltage; according the nucleus usage content, adjusting the operating voltage. The invention reduces the electric power waste, and makes the property of control processor best.

Description

technical field [0001] The present invention relates to a power supply control device and method for a multi-core processor, in particular to a power supply for a multi-core processor that can independently adjust the operating voltage of each core according to the usage of each core in a processor with multiple cores Control device and method thereof. Background technique [0002] Due to the increasing demand for high-speed processors, processors have evolved from single-core processors to multi-core processors. A multi-core processor is provided with multiple cores in one processor, and since the multiple cores share processing operations, processing performance can be improved. In addition, compared with the use of adding several processors, since parts other than the core can be shared, there are advantages of low manufacturing cost and miniaturization. [0003] The aforementioned multi-core processors are expected to consume more power than single-core processors. Ta...
