Description

technical field [0001] The invention belongs to the field of computer applications, and in particular relates to a PCIe-based multi-FPGA dynamic configuration device and method. Background technique [0002] With the rapid development of computer application technology, the application scenarios are diversified, and the application requirements are also constantly changing. It is often necessary to adjust and upgrade the device functions according to the actual needs of the site. FPGA (Field Programmable Gate Array, Field Programmable Gate Array) chip is a programmable integrated circuit based on hardware description language, which can use special hardware description language to design logic circuits, and realize different logic functions according to the actual needs of the site. At present, FPGA chips are based on RAM (Random Access Memory) technology, and the FPGA program will be lost after power failure, so it is necessary to use a special memory chip to still be able ...
