Application of Xilinx ZYNQ FPGA development board in artificial intelligence image processing

PYNQ-Z2 is a platform based on Xilinx ZYNQ-7000 FPGA. In addition to inheriting the powerful processing performance of the traditional ZYNQ platform, it is also compatible with the Arduino interface and the standard Raspberry Pi interface. This makes the PYNQ-Z2 extremely scalable and Open source. PYNQ is a new open-source framework that enables embedded programmers to give full play to the functions of Xilinx Zynq All Programmable SoC (APSoC) without designing programmable logic circuits. Different from the conventional method, through PYNQ-Z2, users can use Python to program APSoC, and the code can be developed and tested directly on PYNQ2. Through PYNQ-Z2, the programmable logic circuit will be imported as a hardware library and programmed through its API in basically the same way as importing and programming a software library.
