| Abstract(in English) | This paper proposes an extension of distributed control, which enables efficient run-time scheduling of variable latency operations, to multiple dataflow graphs. Conventional high-level synthesis methods determine the execution schedule of operations statically assuming that their latencies are fixed. However, actual circuits contain so-called variable latency units whose execution cycles may vary depending on various run-time factors. Although Del Barrio, Pilato, and Yamashita have proposed distributed control methods which can efficiently control circuits with such units, they only handles a single dataflow graphs. Our method extends the Del Barrio's distributed control to handle multiple dataflow graphs. It enables dynamic scheduling of operations beyond the boundaries of dataflow graphs which results in fewer execution cycles than those by conventional centralized control with loop scheduling and trace scheduling. |
