Abstract

The invention discloses an OpenVPX framework-based high-speed backboard. The backboard comprises a bus interface circuit and a support module realized by adopting an SOC hardware circuit, wherein thebus interface circuit comprises an exchange board slot position, three signal processing board slot positions, a collection board slot position, an interface conversion board slot position and a powerboard slot position. Through the support module, configuration management of load board cards carried by the slot positions is realized, which comprises the processes of receiving a synchronous signal and a reset signal provided by the exchange board slot position, transmitting the signals to other slot positions, and setting a state of an I / O pin during initialization to configure function states of the slot positions; and the OpenVPX framework-based high-speed backboard provided by the invention solves the problems of complex design and poor flexibility and expansibility of an existing 3U VPX bus communication circuit.

Description

technical field [0001] The invention belongs to the technical field of high-performance embedded real-time processing circuits, and in particular relates to a high-speed backplane based on the OpenVPX architecture. Background technique [0002] The main function of the high-speed communication interconnection backplane is to realize high-speed signal interconnection between modules on the backplane. The current high-speed communication interconnection backplane is often designed according to the actual system application, the topology and hierarchical division are not obvious, the modules on the backplane are not universal, the circuit design is complicated, and the flexibility and scalability of the circuit are poor. [0003] The OpenVPX standard is a high-reliability computer standard issued by the VITA organization for military, aerospace, national defense and other fields to solve the compatibility and interoperability problems between devices from different manufacturer...
