Center node: "Minimizing Register Requirements under Resource-Constrained Rate-Optimal Software Pipelining"
  Abstract: In this paper we address the following software pipelin-ing problem: given a loop and a machine architecture with a fixed number of processor resources (e.g. function units), how can one construct a software-pipelined schedule which runs on the given architecture at the maximum possible iteration rate (a la rate-optimal) while minimizing the number of registers? The main contributions of this paper are: * First, we demonstrate that such problem can be described by a simple mathematical formulation with precise optimization objectives under periodic linear scheduling framework. The mathematical formulation provides a clear picture which permits one to visualize the overall solution space (for rate-optimal schedules) under different sets of con straints. * Secondly, we show that a precise mathematical formulation and its solution does make a significant performance difference! We evaluated the performance of our method against three other leading contemporary heuristic methods: Huff 's Slack Scheduling [9], Wang, Eisenbeis, Jourdan and Su's FRLC [23], and Gasperoni and Schwiegelshohn's modified list scheduling [6]. Experimental results show that the method described in this paper performed significantly better than these methods.
