Asnchronous Wrapper for Heterogeneous Systems

  title={Asnchronous Wrapper for Heterogeneous Systems},
  author={David S. Bormann and Peter Y. K. Cheung},
This paper presents a low latency, high bandwidth and reliable interface between asynchronous and synchronous subsystems. The approach relies on stretching the clock to prevent metastability in the data flip-flops rather than simply waiting for the data flip-flops to resolve metastability. However, unlike existing clock stretching approaches, ours almost never needs to stretch the clock so the optimum clock frequency can be maintained. We assume a bundled data constraint for communication… CONTINUE READING
