Problems solved by technology

However, at present, most VPX bus-based signal processing boards have only one set of external high-speed data buses with the same function, without considering the redundant backup of high-speed data buses, which makes it difficult to guarantee their working reliability under extremely harsh environmental conditions.

Abstract

The invention discloses a reconfigurable/dual redundancy VPX3U signal processing carrier board based on Soc, under VPX control surface 1GEx1 signalization, a carrier board Soc controller can perform control command dynamic loading and logical function on-line reorganization on a high-performance reconfigurable FPGA (Field Programmable Gate Array), and board-level power and timer management and condition monitoring are completed; a reconfigurable FPGA chip is in interaction with front-end received signals through a standard FMC interface, and multi-function real-time digital signal processing is realized according to a loading program. Meanwhile, a dual-redundancy data bus interface is designed in a VPX connector, and a signal processing carrier board can be in data interaction with other board cards such as a master control switch card, an adjacent board card and the like in the system by a VPX dual redundancy data bus interface.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and more specifically relates to a Soc-based reconfigurable / double redundant VPX3U signal processing carrier board. Background technique [0002] The signal processing carrier board with FPGA as the core, as a digital front-end high-speed signal processing module, is widely used in airborne / shipborne information load systems, measurement and control / communication / navigation equipment, signal test and analysis instruments and other fields. Traditional FPGA signal processing carrier boards are usually only designed for a single function, and only focus on the improvement of a single performance. They cannot dynamically configure circuit functions according to actual needs, and their flexibility, versatility, and scalability are poor. [0003] VPX is a next-generation advanced embedded platform bus standard formulated by VITA to meet the requirements of high reliability and high ba...
