Abstract
An instruction scheduling method and an instruction scheduling system for a reconfigurable array processor. The method includes: determining whether a fan-out of a vertex in a data flow graph (DFG) is less than an actual interconnection number of a processing unit in a reconfigurable array; establishing a corresponding relationship between the vertex and a correlation operator of the processing unit; introducing a register to a directed edge, acquiring a retiming value of each vertex; arranging instructions in such a manner that retiming values of the instruction vertexes are in ascending order, and acquiring transmission time and scheduling order of the instructions; folding the DFG, placing an instruction to an instruction vertex; inserting a register and acquiring a current DFG; and acquiring a common maximum subset of the current DFG and the reconfigurable array by a maximum clique algorithm, and distributing the instructions.
