Comparative analysis of double-edge versus single-edge triggered clocked storage elements

We present a comparison of Double-Edge Triggered clocked Storage Elements (DETSE) with their single-edge triggered counterparts in terms of delay and power consumption. In general, Latch-Mux based DETSE perform better then their single-edge counterparts while double-edge triggered flip-flops exhibit performance degradation. Up to 15% improvement in Energy-Delay Product (EDP) of Latch-Mux designs is achieved when using DETSE. The presented results indicate that the use of DETSE is a good choice when low-power operation is required.
