Abstract:
A power control circuit for saving power consumption of an electronic apparatus having at least one circuit, said power control circuit comprising:a processing start detecting device that detects occurrence of an index indicative of start of execution of processing by said electronic apparatus; a processing termination detecting device that detects termination of the processing started to be executed by the occurrence of said index; and a power control device that is responsive to detection of the termination of the processing by said processing termination detecting device, for performing control of reducing power consumption of said at least one circuit of said electronic apparatus, for a time period after the termination of the processing and until next occurrence of said index is detected by said processing start detecting device, wherein said electronic apparatus performs the processing using slots changed by a slot timing signal having a predetermined frequency, said processing start detecting device detecting said index indicative of the start of execution of the processing by detecting generation of said slot timing signal.
