Asynchronous Data Communication with Low Power for GLAS Systems

In this paper, we propose an asynchronous wrapper with new handshake circuits for the data communication in GALS systems. The handshake circuits include two data-ports and a local clock controller. we present two approaches for the implementation of dataports; one with pure standard cells and the other with Muller-C elements.The detailed design methodology is given and the circuits are validated with VHDL and circuits simulation in standard CMOS technology.
