a Real-time image recognition project with RTL accelerator and ZYNQ Architecture
本项目实现了一个实时目标检测系统，采用纯FPGA的RTL逻辑实现yolov3tiny的神经网络加速器，并利用zynq构建了图像采集及显示回路。 本项目的加速器参考了项目https://github.com/adamgallas/fpga_accelerator_yolov3tiny ，本项目仅对zynq7000进行了针对性的重构，相关设计思路请参考源项目。
This project implements a real-time target detection system, using FPGA RTL logic to implement yolov3tiny's neural network accelerator, and using zynq to build an image acquisition and display loop.

若您采用的板卡架构不是zynq-7000，请检查DSP型号是否为DSPE1，若不是，则需要对卷积IP进行适配后再编译运行。 if your board is not zynq7000,Check whether the DSP model is DSPE1. If not, you need to adapt the convolutional IP before compiling and running.
copy all files under the YOLOV3TINY-ZYNQ/sd folder to your sd card.
Then insert the SD card into the zynq board.
Open vitis and set the folder VitisProject (path=YOLOV3TINY-ZYNQ/VitisProject) as your vitis workspace.
Then run the application named detection_displayloop
Run the project,the video stream will be ouput in HDMI_OUT port, connect it into any screen and you will see the result.The Running status parameters will be output in uart.
将YOLOV3TINY-ZYNQ/sd中的所有文件拷贝至sd卡中，并将sd卡插入到开发板上。
打开vitis并将 .\YOLOV3TINY-ZYNQ\VitisProject 文件夹设为工作空间。
然后运行名为 detection_displayloop的application。
程序烧录完成并开始自动运行后，视频流会从开发板的HDMI_OUT接口输出，连接视频接口到任意显示器即可观察到视频流的输出，连接UART口至PC，利用putty（波特率115200）也能观察到运行状态等参数输出。
