Abstract

The invention discloses a signal processing system with dual processing nodes based on Arria10 FPGA, which has the advantages of high processing density, large storage capacity, fast transmission rate, and flexible external interconnection. The signal processing system includes two identical processing nodes; Each processing node is composed of an FPGA chip and a cache DDR4 and QSFP optical module connected to the FPGA chip; the FPGA chips of the two processing nodes are connected through 8 pairs of high-speed XCVR buses; the signal processing system has 7 VPX connectors, respectively for: P 0 ,P 1 ,P 2 ,P 3 ,P 4 ,P 5 and P 6 ;The signal processing system is connected to the external main control board through the VPX connector, and the data transmission between the signal processing system and the external main control board and between the two processing nodes inside the signal processing system is realized through the exchange chip of the three major protocols. The switching chip refers to the serial fast input and output SRIO switching chip, the peripheral component interface PCI switching chip and the Ethernet switching chip.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a signal processing system based on Arria10 FPGA with dual processing nodes. Background technique [0002] Since the 20th century, with the rapid development of intelligent information technology and highly integrated chip technology, real-time signal processing technology has been iteratively updated, and has been widely used in various fields such as radar data processing, aerospace industry control, and artificial intelligence communication. The main functions of real-time signal processing technology include the acquisition, extraction, conversion, filtering, identification and other processing of digital and analog signals to obtain the signal form required by the project. However, the traditional signal processing platform has gradually been unable to meet the increasingly large processing requirements, and the real-time signal processing system architecture is in...
