Dynamic intelligent scheduling and control of reconfigurableparallel architectures for computer vision/image processing

摘要

A system for dynamic intelligent scheduling and control (DISC) ofreconfigurable parallel processors is presented. The purpose of thesystem is to provide a rapid prototyping capability for computervision/image processing tasks. The scheduler particularly addresses theproblems of algorithms with execution times that depend on the imagedata and processing scenarios that vary dynamically based on the inputimage. Since conventional scheduling methods cannot propose schedulesfor most masks of this type, a dynamic controller is used to schedulethe task and reconfigure the machine on the fly. This dynamic schedulingsystem attempts to balance the overall processing scenario with theneeds of the individual routines that make up the task. Theimplementation of this system is discussed, with emphasis on thescheduling heuristics and the use of the system for prototyping computervision/image processing tasks. Testing was done on a number of tasksthat exercised different aspects of the scheduling strategy
