Abstract

The invention provides a mapping scheme optimization method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining an initial first mapping scheme which is used for mapping a to-be-executed first neural network to a plurality of processing cores of a many-core system, each processing core is used for executing at least one neuron of the first neural network, and the first mapping scheme comprises inter-core connection among the processing cores; reconstructing the inter-core connection in the mapping scheme of the (n-1) th inter-core reconstruction to obtain a mapping scheme of the nth inter-core reconstruction; judging whether the nth inter-core reconstruction mapping scheme meets an inter-core optimization condition or not; and determining an optimized second mapping scheme according to the nth inter-core reconstruction mapping scheme under the condition that the nth inter-core reconstruction mapping scheme meets a preset inter-core optimization condition. According to the embodiment of the invention, data transmission between cores can be reduced, and the routing pressure of a many-core system is relieved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular, to a method and apparatus for optimizing a mapping scheme, an electronic device, and a readable storage medium. Background technique [0002] The popularity of intelligent applications makes neural network computing more and more important. However, it is difficult for general-purpose processors to meet the large amount of computation and storage required by neural networks. For this reason, related technicians have developed many-core systems with neural network acceleration architectures. When the many-core system executes the neural network, many neurons of the neural network are spatially distributed on different processing cores, that is, the mapping scheme is obtained. Since the data transfer between the processing cores is realized through the routing system (network-on-chip) of the many-core system, and the neural network itself has a large amo...
