The PYNQ-Z1 board is designed to be used with PYNQ, a new open-source framework that enables embedded programmers to exploit the capabilities of Xilinx Zynq All Programmable SoCs (APSoCs) without having to design programmable logic circuits. Instead, the APSoC is programmed using Python and the code is developed and tested directly on the PYNQ-Z1. The programmable logic circuits are imported as hardware libraries and programmed through their APIs in essentially the same way that the software libraries are imported and programmed. The PYNQ-Z1 board is the hardware platform for the PYNQ open-source framework. The software running on the ARM A9 CPUs includes:Web server hosting the Jupyter Notebooks design environment The IPython kernel and packages Linux Base hardware library and API for the FPGA.
