抄録

VLSI-oriented dynamic data-driven processors Qv-x is constructed by a self-timed elastic superpipeline, which has inherent buffering capability of instantaneous fluctuations in packet-flow. Thus the pipeline can smooth the packet-flow in the processor, so that it is recognized as a very promising hardware implementation method for dynamic data-driven processors. Due to the structure of programs and/or the characteristics of input packet streams, however, excessive fluctuations in packet-flow may happen, which lead to the performance degradation. To eliminate ill effects of excess fluctuations, elastic queue-buffers are also incorporated in the Qv-x. This paper proposes an allocation method of queue buffers in the Qv-x to cope with different sources of the fluctuation and provides the quantitative evaluation of buffering capability of fluctuations through extensive simulation experiments. The simulation results show that, by an allocation method, large fluctuations can be absorbed and full performance of the processor can be achieved.
