Signal-processing board

The invention provides a signal-processing board, which comprises a plurality of FPGA processing nodes, an FPGA main control module, a PCI interface module, a clock module and a power supply module, wherein the plurality of FPGA processing nodes are interconnected by an interconnection bus in a totally communicated topological structure and the interconnection bus is used for transmitting a high-speed data signal; the FPGA main control module is interconnected with the plurality of FPGA processing nodes through a shared bus which is used for transmitting a control signal; the PCI interface module is connected with the FPGA main control module through a local bus; the clock module is connected with the FPGA main control module, controlled by the main control module and used for supplying aworking clock to the signal-processing board; and the power supply module is used for supplying a voltage required by the signal-processing board. The topological structure of the plurality of FPGA processing nodes of the signal-processing board is flexible and the reconfiguration of the interconnection structure can be implemented according to specific application.
