Abstract
The present invention relates to a processor capable of power consumption scaling, and more particularly, to a technique that variably controls the energy consumption of a processor according to the energy capacity being supplied by providing a pipeline register with a bypass function so as to control the operating frequency of the processor.
Claims7
A processor capable of power consumption scaling, the processor comprising:
- a plurality of functional units sequentially performing functions;
- a plurality of pipeline register sets provided between the plurality of functional units, storing calculation results of functional units corresponding to previous stages of a pipeline and having bypass functions;
- a system clock control unit supplying clock signals to the plurality of pipeline register sets;
- and
- a bypass control unit supplying a bypass signal to a pipeline register set selected according to predetermined conditions among the plurality of pipeline register sets.
