Abstract

The invention discloses an adaptive variable redundancy 3U signal processing backboard based on a VPX bus. Through two paths of SRIO (Serial RapidIO)x4 and two paths of PCIe (Peripheral Component Interface Express)x1, the dual redundancy point-to-point interconnection of high-speed data is realized; through two paths of 1GE (1GB Ethernet)x1, the dual redundancy point-to-point interconnection of a control command is realized; and through two paths of SRIOx4 and two paths of 1GEx1, data interaction between two master control switching boards is realized so as to realize the hot backup of the whole system. The whole signal processing backboard topology framework can expand the amount and the type of board cards supported by the backboard according to a current signal processing task, and therefore, the backboard exhibits good expansibility and flexibility, and can adapt to the tendency of current aerospace field development.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and more specifically relates to an adaptive variable redundancy 3U signal processing backplane based on a VPX bus. Background technique [0002] With the rapid development of digital signal processing technology and embedded computer technology, in the field of aerospace, the structure form (especially the bus structure), processing performance, data throughput rate, miniaturization and robustness of the aircraft information system load platform And output power, etc. put forward more stringent requirements, requiring the load platform to have higher reliability performance, wider bus bandwidth and more flexible data interaction capabilities. [0003] A variety of backplane bus topologies including CAN, CPCI and VME are applied to the payload platform of the aircraft information system to realize comprehensive information processing under the condition that the payload carrying...
