Abstract
Provided is an apparatus and method for controlling power to a reconfigurable array processor. The method may determine one or more function units (FUs) as activation function units (FUs) and deactivation FUs among a plurality of FUs included in the reconfigurable array processor. The processor may interrupt power supplied to the deactivation FUs.
Claims20
A power control method of a processor including a plurality of function units (FU), the method comprising:
- determining at least one activation FU and at least one deactivation FU, from among the plurality of FUs;
- calculating a performance of the plurality of FUs based on a compiling result of the at least one activation FU;
- and
- controlling the supply of power with respect to the plurality of FUs based on the calculated performance of the plurality of FUs.
A power control apparatus of a processor including a plurality of function units (FU), the apparatus comprising:
- a function unit (FU) determination unit to determine at least one activation FU and at least one deactivation FU, from among the plurality of FUs;
- a performance calculation unit to calculate a performance of the plurality of FUs based on a compiling result of the at least one activation FU;
- and
- a power control unit to control power supply with respect to the plurality of FUs based on the calculated performance of the plurality of FUs.
A processor comprising:
- a plurality of functional units configured to process instructions;
- and
- a power control unit configured to supply power to one or more of the plurality of functional units and to deactivate power to one or more of the remaining plurality of functional units, during a processing cycle, based on the processing performance of the plurality of functional units.
