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 Soc-based reconfigurable / double redundant VPX3U signal processing carrier board. Under the action of the VPX control plane 1GEx1 signal, the onboard Soc controller dynamically loads control commands and logic for high-performance reconfigurable FPGAs. The function is reconfigured online, and board-level power supply, clock management and status monitoring are completed; the reconfigurable FPGA chip interacts with the front-end receiving signal through the standard FMC interface, and realizes multi-functional real-time digital signal processing according to the loading program. At the same time, a dual redundant data bus interface is designed in the VPX connector, and the signal processing carrier board can exchange data with other boards in the system, such as the main control switching board and adjacent boards, through the VPX dual redundant 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...
