Scheduling as Rule Composition

Scheduling as Rule Composition
Bluespec is a high-level hardware description language used for architectural exploration, hardware modeling and synthesis of semiconductor chips. In Bluespec, one views hardware as a collection of stateful elements (e.g., registers, memories) and describes its behavior using rules, or Guarded Atomic Actions which modify these elements. All legal behaviors of a Bluespec program can be explained in terms of rules being applied in some sequence. Scheduling is the process of selecting which rules to execute in parallel while maintaining this semantic invariant. The scheduling decision can have a large impact on critical design properties such as pipeline concurrency and clock frequency. What constitutes a good schedule often depends upon the application and requires the designer’s input. In this paper we introduce BTRS, the kernel language for Bluespec and use it to explore the task of scheduling. We view scheduling as the process of restricting a Bluespec design’s non-deterministic ...
