Abstract

A real-time control program for a turbojet engine has been implemented on a four-processor computer, achieving a speedup of 3.38 times the speed of a sequential version of the same program on a single processor. The concurrent program was produced from a sequential program by subjecting the sequential program to global, hierarchical interprocedural data-flow analysis and timing measurements. A static schedule for the constituent tasks of the control program on the four processors was determined using a heuristic algorithm based on the critical-path method. The approach should be applicable to a variety of control and related programs where iterative tasks with well-bounded execution times are computed in systems with hard real-time requirements.<>
