<p>PROBLEM TO BE SOLVED: To provide a reconfigurable LSI which reduces the time required for the start of operation of a reconfigured arithmetic system or in which malfunction is suppressed.SOLUTION: A configurable LSI includes a configuration memory in which configuration data is stored, a plurality of processor elements which have reconfigurable logic circuits respectively and are configured into desired arithmetic states on the basis of configuration data, a plurality of configuration registers which are provided correspondingly to the plurality of processor elements respectively and in which configuration data defining the arithmetic states of respective corresponding processor elements is stored, and a power control unit which controls supply/shutdown of power to the processor elements. The power control unit starts power supply to an operation object processor element to be configured into an arithmetic state on the basis of the configuration data, out of the plurality of processor elements, and then the operation object processor element starts operation.</p> |
