Description

technical field

[0001] The invention discloses a neural network acceleration method based on multi-block FPGA cooperative processing, and relates to the field of neural network optimization. Background technique

[0002] Neural network (Neural Networks, NN) is a complex network system formed by a large number of simple processing units (called neurons) that are widely connected to each other. It reflects many basic features of human brain function and is a highly complex network. Nonlinear dynamical learning systems. Neural network has large-scale parallelism, distributed storage and processing, self-organization, self-adaptation and self-learning capabilities, and is especially suitable for dealing with imprecise and fuzzy information processing problems that need to consider many factors and conditions at the same time. One layer of the existing neural network model cannot be perfectly implemented in parallel on one FPGA, so the processing performance of the neural networ...
