Abstract
In this paper, we propose a RZ/HRZ mixture data transmission method for the asynchronous circuit design to reduce Power consumption. The dual-rail data with Rf decoding scheme is used to design asynchronous circuit, and it is easy to get a completion signal of the data validity from the native data as contrasted with sin91e-rail. However, the dual-rail scheme suffers from large chip area and increasing of Power consumption from all signals by the switching of the return-to-zero. We need to diminish number of circuit switching. The proposed RZ/HRZ data transmission reduces a switching activity to about 50% and it shows 23% lower power consumption than the conventional dual-rail coding with RZ's.
