Abstract(in English) | In this paper, we propose a dynamic power optimization method by latch insertion for asynchronous RTL models. In data-paths of the asynchronous RTL model, the proposed method inserts latches before combinational circuits to prevent the unnecessary operations. We also study a latch insertion by considering critical path delays to satisfy latency constraint. In the experiment, we applied the proposed method for three benchmarks and evaluated the reduction effect of dynamic power consumption. Compared to synchronous circuits with traditional operand isolations, the proposed latch insertion method reduced the dynamic power consumption by 28.2% on the average. On the other hand, the latch insertion method by considering critical path delays reduced the dynamic power consumption by 11.5% on the average. |
