Description

technical field [0001] The invention belongs to the field of computer application, in particular to a PCIe-based multi-FPGA dynamic configuration device and method. Background technique [0002] With the rapid development of computer application technology, application scenarios are diversified, and application requirements are constantly changing. It is often necessary to adjust and upgrade equipment functions according to the actual needs of the field. FPGA (FieldProgrammable Gate Array, Field Programmable Gate Array) chip is a programmable integrated circuit based on hardware description language. It can use a 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 all based on RAM (Random Access Memory, random access memory) technology, and the FPGA program will be lost after a power failure, so it is necessary to use a special memory chip that can still sav...
