Abstract
A semiconductor integrated circuit is provided in which power consumption of each functional block can be determined. The semiconductor integrated circuit comprises: first through third signal processing circuits each operating in synchronization with first through third externally supplied clock signals; first through third counters each counting first through third clock signals; a bus interface circuit outputting a plurality of count values that the first through third counters counted; a clock enable signal generating circuit to generate first through third clock enable signals each controlling the supply of the first through third clock signals to the first through third signal processing circuits; and a counter control circuit supplying a plurality of counter reset signals and a plurality of counter enable signals for resetting and operating the first through third counters, respectively.
