本文介绍了基于HLS的YOLOv3在FPGA上的实现过程，选用了AX7350开发板进行网络加速。主要内容包括使用开源YOLOv3进行网络训练和量化，生成加速器IP核，搭建SOC硬件平台，导出bit流文件，以及使用Petalinux制作SD镜像启动文件。此外，还详细说明了如何通过SDK工具编写驱动生成.elf文件，并进行上板调试，确保软件和硬件输出一致。文章还提供了GitHub上的相关代码和资源链接，包括Petalinux代码、Vivado工程和量化代码，方便开发者直接使用或参考。 YOLOv3是一个高效、快速的目标检测算法，它能够在图像中实时识别多个对象。FPGA（Field-Programmable Gate Array）是一种可以重新配置的数字逻辑电路。将YOLOv3部署到FPGA上，可以实现网络加速，满足实时性要求高的应用场景。在本文中，作者详细描述了基于HLS（High-Level Synthesis）的YOLOv3在FPGA上的实现过程。 进行网络训练和量化是实现过程的第一步。YOLOv3模型的训练使用开源代码进行，量化过程则涉及将训练好的模型参数转化为整数形式，以减少FPGA实现过程中的计算复杂度。生成加速器IP核是将训练和量化后的模型部署到FPGA上的重要步骤，IP核是一种可以重复使用的模块化电路设计。 接下来，作者详细描述了如何搭建SOC（System on Chip）硬件平台。SOC是一种将计算机系统的主要部件集成到单个集成电路芯片上的技术。在本文中，SOC硬件平台的搭建需要导出bit流文件，这是一种用于描述FPGA硬件配置的文件格式。此外，作者还介绍了如何使用Petalinux制作SD镜像启动文件。Petalinux是基于Linux的嵌入式开发平台，SD镜像则是一种存储了操作系统和相关软件的存储卡映像文件。 软件和硬件的衔接部分也是本文的一个重点。作者说明了如何通过SDK（Software Development Kit）工具编写驱动生成.elf文件，并进行上板调试。.elf文件是可执行链接格式文件，用于在嵌入式系统上加载和运行程序。上板调试是指在实际硬件上测试程序的过程，以确保软件运行结果与硬件预期一致。 为了方便开发者使用和参考，作者还提供了GitHub上的相关代码和资源链接。这些资源包括Petalinux代码、Vivado工程和量化代码。Petalinux代码是用于制作Petalinux操作系统的源码，Vivado工程则是Xilinx公司推出的用于FPGA设计的软件工程。量化代码是用于模型量化处理的程序代码。 本文详细介绍了基于HLS的YOLOv3在FPGA上的实现过程，包括网络训练、量化、生成IP核、搭建硬件平台、制作启动文件以及驱动开发和调试等关键步骤。同时，提供了丰富的代码和资源链接，为开发者提供了便利的参考和使用途径。
