This paper presents a system for dynamic intelligent scheduling and control of reconfigurable parallel processors. The purpose of the system is to provide a rapid prototyping capability for computer vision/image processing tasks. The scheduler particularly addresses the problems of algorithms with execution times that depend on the image data and processing scenarios that vary dynamically based on the input image. Since conventional scheduling methods cannot produce schedules for most tasks of this type, a dynamic controller is used to schedule the task and reconfigure the machine “on the fly.” This dynamic scheduling system attempts to balance the overall processing scenario with the needs of the individual routines that make up the task. This paper discusses the implementation of the DISC (Dynamic Intelligent Scheduling and Control) system. Emphasis is on the scheduling heuristics as they apply to a reconfigurable parallel processor, the information in the system database, and the use of the system for prototyping computer vision/image processing tasks on a partitionable parallel system.
