Abstract

Cluster assignment is a compiler optimization that plays an important role in performance of programs. However, the existing algorithms only work on straight-line program area, and is difficult to be optimal. Aiming at these problems, this paper proposed a unified cluster assignment and instruction scheduling method based on integer linear programming. This method used 0-1 decision variables to represent cluster assignment, local instruction scheduling and global scheduling of inter-cluster transfer instructions, and formulated dependency and processor resources competition between instructions into linear constraints, eventually got an integer linear programming model whose objective was to minimize the estimated execution time of the function. Experimental results show that the cluster assignment and scheduling scheme from solving the model significantly outperforms the existing algorithms on accelerating programs, and the time required to solve the model is acceptable.
