One of the benefits of coarse grained dynamically re-configurable processor array(DRPA) is its low dynamic power consumption by operating a number of processing elements(PE) in parallel with low clock frequency. However, in the future advanced processes, leakage power will occupy a considerable part of the total power consumption, and it may degrade the advantage of DRPAs. In order to reduce the leakage power, a fine grained Power Gating(PG) is applied to a DRPA, MuCCRA-2.32b, and leakage power and area overhead are measured. We evaluated the effect of two control modes; Pair and Unit Individual based on layout design and real applications. It appears that by applying PG for ALUs and SMUs in PEs individually, 48% of leakage power can be reduced with 9.0% of area overhead.
