Abstract
The present invention is directed to a power control circuit for reducing wasteful power consumption of an electronic apparatus such as a digital signal processor. More specifically, a preferred embodiment of the present invention includes a processing detecting device that detects occurrence of an index indicative of a start of execution of a process by the electronic apparatus, a processing termination detecting device for detecting a termination of the processes, and a power control device that responds to the detection of the termination of the process for reducing the power consumption by at least one circuit element of the electronic apparatus for a time period after the termination of the processing, and until the next occurrence of the index indicative of another start of execution of a process.
