Abstract :
We present a method for decomposing a high-level program description of a circuit into a system of concurrent modules that can each be implemented as asynchronous pre-charge half-buffer pipeline stages (the circuits used in the asynchronous R3000 MIPS microprocessor). We apply it to designing the instruction fetch of an asynchronous 8051 microcontroller, with promising results. We discuss new clustering algorithms that will improve the performance figures further.
