ABSTRACT:
An apparatus for suspending power of a processing system having a plurality of core blocks connected in series includes a system controller which receives input data and determines whether to suspend a supply of power to the processing system based on the input data. A converter converts a format of the input data, and a determining unit determines whether the converted input data is valid data. Valid data is data which will be processed by the plurality of core blocks. A series of controllers in the apparatus shift output from the determining unit through the series of controllers. Each controller temporarily stores the output from the determining unit prior to shifting the output from the determining unit to a next controller in the series of controllers. Also, each controller is associated with one of the plurality of core blocks, and controls a supply of power to the associated core block based on output from the system controller and the output from the determining unit temporarily stored therein.
