Reconfigurable task processing system, scheduler and task scheduling method

The invention relates to a reconfigurable task processing system, a scheduler and a task scheduling method. The system comprises the scheduler, a layout and a resource manager, wherein the scheduler is used for extracting space-time attribute parameters of a received task, calculating the slackness of the task, generating a potential layout time table PPTL of a task layout, sending the PPTL to the layout, scheduling tasks in a queue to be scheduled according to a received layout result fed back by the layout, and sending resource state update information to the resource manager according to the scheduling result; the layout is used for performing a layout research on the resource provided by the resource manager according to each time in the PPTL after receiving the PPTL, obtaining a start time and a corresponding resource of the task and feeding back the layout result to the scheduler; and the resource manager is used for updating a resource state in a task layout area when receivingthe resource state update information sent by the scheduler, and providing a three-dimensional search space for the layout so as to improve the scheduling efficiency of the task.
