The invention relates to a processing module capable of reconstructing signals based on a VPX bus, comprising a high-speed board card, a front panel, a radiating cover board, a module lifter, a positioning pin and a locking mechanism part. The high-speed board card comprises a VPX 6U standard high-speed printing board, a power supply circuit, an MPC7448 processor chip, an MV64460 bridging chip, a FPGA (Field Programmable Gate Array) chip, a DDR SDRAM (Digital Data Receiver Synchronous Dynamic Random Access) and FLASH, a high-speed high density electric connector, an opto-electrical converter and a kilomega Ethernet interface. The high-speed board card comprises four processing nodes, each processing node comprises one MPC7448 processor chip, one MV64460 bridging chip and the DDR SDRAM; the MV64460 bridging chip is respectively connected with the MPC7448 processor chip and a storage DDR SDRAMFPGA through a CPU interface, the DDR SDRAM interface and a Device interface.
