Embodiment Construction

[0042] like figure 1 As shown, the on-chip network routing communication method for brain-inspired processors in this embodiment includes:

[0043] 1) Stage 1: The interaction of neurons input to the SNN model;

[0044] 2) Stage 2: According to the interaction of neurons in the SNN model, neurons with higher communication frequencies are divided into different sub-blocks, and then these sub-blocks are mapped to the brain-like processor based on the NoC structure;

[0045] 3) Stage 3: Multiple multicast paths are created for each neuron on the NoC structure of the brain-like processor, and these multicast paths are stored in the multicast path SRAM corresponding to the neuron;

[0046] 4) Stage 4: The brain-like processor imitates the behavior of the pulse neuron through the processing unit PE. When the neuron generates a pulse, the processing unit PE accesses the local multicast path SRAM to obtain the multicast path corresponding to the neuron, and sends The multicast data ...

Abstract

The invention discloses an on-chip network routing communication method and an on-chip network for brain-inspired processors. The method of the invention includes dividing neurons with higher communication frequencies into different sub-blocks according to the interaction of neurons in the SNN model Mapped to the brain-like processor; multiple multicast paths are created for each neuron on the NoC structure of the brain-like processor. The brain-like processor imitates the behavior of pulsed neurons through the processing unit PE. When the neuron generates a pulse , the processing unit PE accesses the local multicast path SRAM to obtain the multicast path corresponding to the neuron, and outputs the multicast data packet to the multicast path, and the multicast data packet is transmitted in the network on chip until the transmission of the multicast path is completed . The invention can effectively support the mass communication of brain-like processors based on NoC interconnection without bringing complicated design and storage overhead to NoC.

Description

technical field [0001] The invention relates to brain-inspired computing technology, in particular to an on-chip network routing communication method and on-chip network for a brain-inspired processor. Background technique [0002] Brain-like computing refers to the use of Very Large Scale Integrated (VLSI) systems to mimic the neurobiological architecture presented in the nervous system. The brain-inspired computing platform is the infrastructure of brain-inspired computing technology, which can realize the calculation and interconnection of sea neurons, and provide a running platform for brain-inspired computing algorithms. In recent years, many brain-like processors have been successfully developed at home and abroad, including TrueNorth from IBM, Loihi from Intel, DYNAPs from the Swiss Institute of Neural Information, SpiNNaker from the University of Manchester, and Tianji from Tsinghua University. [0003] Network-on-Chip (NoC) has the characteristics of flexibility, s...
