Abstract

The invention relates to radar signal processing and relevant technical fields, in particular to a network and SRIO data exchanging plate based on a VPX bus and a control method for the network and SRIO data exchanging plate. The network and SRIO data exchanging plate based on the VPX bus comprises a power module, an FPGA (field programmable gate array) control module, a first SRIO exchanging module, a second SRIO exchanging module, a network exchanging module, a network interface module, an FLASH module, a debugging serial port module, an FPGA debugging port and an LED (light emitting diode) lamp display module. The problems that a data transmission mode of the existing signal processing system is inflexible, and the existing signal processing system does not have a system reconfigurable function are solved; an SRIO and network exchanging chip is adopted; a 12-channel SGMII (serial gigabit media independent interface) network and a 10-channel SRIO port can be exchanged; and the 10-channel SRIO port can be configured into an X4 or X1 SRIO exchanging port according to different application requirements. The data exchanging plate has the advantages that the data exchanging plate is high in integration level and real-time in exchanging and has abundant ports.

Description

technical field [0001] The invention relates to radar signal processing and related technical fields, in particular to a VPX bus-based network, an SRIO data exchange board and a control method. Background technique [0002] In the radar signal processing system, data needs to be frequently exchanged between multiple signal processing boards. At present, for the transmission of large amounts of data, most signal processing systems transmit data through external optical fiber or backplane interconnection, but these two connection methods are not flexible enough, and the same backplane cannot meet the connection topology requirements of multiple signal processing systems. The system does not support reconfigurability. For small data transmission, it is transmitted through a network switch, but this method requires additional equipment and too many external network cables. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the pres...
