Integrated circuit-based reconfigurable framework and implementation method

Abstract

The invention discloses an integrated circuit-based reconfigurable framework and an implementation method. The framework comprises an upper-level monitoring circuit located in the first layer, a two-level triple-redundant circuit located in the second layer, and a gate circuit and an output circuit located in the bottom layer; the upper-level monitoring circuit is used for fault diagnosis, control, deployment and reconstruction of a system; the two-level triple-redundant circuit includes circuit-level and module-level triple-redundant design and is used for processing high-speed computation, communication, and measurement and control; the gate circuit is controlled by a gating signal of the upper-level monitoring circuit, and the output of the gate in the current working is the amount sentto the output circuit. The framework adopts a pyramid-shaped architecture, the structural design is studied to improve the system ability to resist the single event effect, the two-level triple-redundant design is combined, and the framework is especially suitable for aerospace application. Compared with the prior art, the framework adopts the pyramid-shaped architecture, so that the reliabilityis high; the ability to resist the single event effect is greatly improved; the hardware and software two-level redundancy design is adopted; the framework has reconfigurability.

Description

technical field [0001] The invention relates to the technical field of power supply controllers, in particular to a reconfigurable architecture based on integrated circuits and an implementation method. Background technique [0002] Field Programmable Gate Array (Field Programmable Gate Array, FPGA), Digital Signal Processor (Digital Signal Processor, DSP) and other VLSIs have rich input and output ports, advanced control methods, and can meet the system multi-channel sampling independent input, multi-channel Features such as PWM independent output are conducive to the integration and performance optimization of aerospace power supplies. But at the same time, VLSIs such as FPGAs are susceptible to various radiations in the universe, such as the probability of single event effects is greatly increased, and the higher the integration of devices, the more significant the impact of single event effects, which seriously restricts digital power supply. Applications in aerospace. ...
