Abstract

The invention relates to an instruction list scheduling method and device, computer equipment and a storage medium. The method comprises the steps of analyzing a data dependency relationship of a to-be-scheduled instruction to obtain all selection nodes for performing instruction selection each time in an instruction scheduling process, and determining instructions of each order in a scheduled instruction list according to an evaluation result of the selection nodes corresponding to each order. The method can ensure that the selected instruction is the optimal result of the current state whenthe instruction is selected each time, the scheduled instruction list is obtained by using the optimal results, the arrangement among the instructions is more compact, and the execution time of the instruction sequence in the original instruction list can be shortened conveniently.

Description

technical field [0001] The present invention relates to the technical field of information technology and computer, in particular to an instruction list scheduling method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of computer technology, multi-core processor computing systems (Multi-core processor Computing System), heterogeneous computing systems (Heterogeneous Computing System) and other multi-processor systems including multiple processors have emerged. Computer system (Multi-processor Computing System). The multiple first processors in the above computer system can process different instructions in parallel according to the instruction lists corresponding to the multiple first processors, so as to improve the processing efficiency of the computer system. [0003] However, the order of instructions in the instruction lists corresponding to the multiple first processors of the computer system may not be reasona...
