TASK ALLOCATION METHOD, TASK ALLOCATION APPARATUS, AND NETWORK-ON-CHIP

摘要

A task allocation method, a chip are disclosed. The method includes: determining a number of threads included in a to-be-processed task; determining, in a network-on-chip formed by a multi-core processor, a continuous area formed by routers-on-chip corresponding to multiple continuous idle processor cores whose number is equal to the number of the threads; if the area is a non-rectangular area, determining a rectangular area extended from the area; and if predicted traffic of each router-on-chip that is connected to a non-idle processor core and in the extended rectangular area does not exceed a preset threshold, allocating the multiple threads of the to-be-processed task to the idle processor cores in the area. According to the task allocation method provided in the embodiments of the present invention, problems of large hardware overheads, a low network throughput, low system utilization are avoided.

主权项

1. A task allocation method, comprising:
determining a number of threads comprised in a to-be-processed task; determining, in a network-on-chip formed by a multi-core processor, multiple continuous idle processor cores whose number is equal to the number of the threads, wherein each of the idle processor cores is connected to a router-on-chip; searching for and determining, in the network-on-chip if an area formed by the determined routers-on-chip is a non-rectangular area, a rectangular area extended from the non-rectangular area; and allocating the threads in the to-be-processed task to the idle processor cores if predicted traffic of each router-on-chip in the extended rectangular area that is connected to a non-idle processor core does not exceed a preset threshold, wherein each of the idle processor cores is allocated one thread.
