Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing system based on FPGA (Field Programmable Logic Gate Array). Background technique [0002] At present, the data processing system in nuclear power plants is mainly based on the CPU (Central Processing Unit) for processing, which uses a serial description method, which needs to be decoded and executed by operating system instructions, and shared memory; and because the memory is shared, it is necessary to perform Access arbitration, and in order to take advantage of access limitations, the consistency of the cache components must be maintained, which will result in lower energy efficiency; and many codes of the operating system and application software of the CPU processor are not disclosed to the application, and can only be used for black-box testing , cannot do white box testing. In addition, the existing data processing systems in nuclear power plants...
