Abstract :
System-on-chip technology raises challenges when smooth interfacing between different functional systems is required. This paper presents the design of an asynchronous interface between irregular sampling and asynchronous microprocessor. The target of this design is to interface an asynchronous microprocessor with front-end devices with high-speed and low-power operation modes depending on the sampling rate. We use GasP FIFOs, as well as several custom-designed modules to implement this interface. Simulation results in Hspice for a CMOSP18 technology shows stable operation of up to 3.1 giga data items/sec (GDI/s).
