With the increasing size and complexity of the today SoC systems,reduction of power consumption has become an important issue and an area of very active research. Clock gating (i.e. switching off the clock input of registers in cycles when they are not used) is one of techniques used in ASIC design to reduce dynamic power. Current FPGA devices contain multiple networks for distribution of clock signal and, in principal, allow for use of the clock gating technique. In this report, we present the results of power consumption measurements on design with and without clock gating technique on so called, which is a master-worker based multiprocessor architecture with MicroBlaze as master and a reprogrammable accelerator as worker. Since the worker may represent significant part of the overall design size, we have implemented the clock gating technique to reduce its power consumption in the IDLE time.
