Research on the design and optimization method of CNN accelerator based on HLS tools
Abstract
Based on the idea of software and hardware co-design, this article uses HLS tools to design and implement a convolutional neural network accelerator on the PYNQ-Z2 platform, and uses the matrix cutting optimization method for convolution operations to balance resource consumption and computing resources , so that the performance of the accelerator is optimized. This article uses the MNIST data set to test the performance of the accelerator IP core. The experimental results show that: for a single image test, the accelerator achieves an acceleration effect of 5.785 compared with the ARM platform, and an acceleration of 9.72 for a 1000 image test. As a result, as the number of test images continues to increase, the performance of the accelerator will become better and better.
