Dependency-driven distribution of synchronous programs

Abstract

In this paper, we describe an automatic synthesis procedure that distributes synchronous programs on a set of desynchronized processing elements. Our distribution procedure consists of three steps: First, we translate the given synchronous program to synchronous guarded actions. Second, we analyze their data dependencies and represent them in a so-called action dependency graph (ADG). Third, the ADG is subsequently partitioned into of sub-graphs where cuts can be made horizontal (for a pipelined execution) or vertical (for a concurrent execution). Finally, we generate for each sub-graph a corresponding component and automatically synthesize a communication infrastructure between these components.
