an arrow computer

Abstract

The invention discloses an arrow-borne computer, comprising: a core processor including a quad-core ARM application processor and a dual-core ARM real-time processor, wherein the quad-core ARM application processor is used to process information of an arrow-borne sensor and control parameters. Computing, the dual-core ARM real-time processor is used for real-time management of external interfaces and real-time information interaction; peripheral interface, which adopts Zynq UltraScale+XCZU28DR processor to integrate and design peripheral interface circuit, including multiple interfaces for connecting external equipment; Computer software, It includes VxWorks real-time operating system, which is used for real-time operation management and control of multiple tasks and input and output management of interface data. The invention can greatly increase the processing capability of the computer system, simplify the circuit structure, effectively reduce the cost and improve the reliability.

Description

technical field [0001] The invention relates to the field of aerospace electronic computers, in particular to an arrow-mounted computer. Background technique [0002] With the rapid development of civil aerospace, higher and higher requirements have been placed on rocket launch services. The volume and weight of the launch vehicle directly determine the cost, so the electronic systems on the rocket are required to have strong computing performance, strong real-time performance, small size, light weight, and reliability. [0003] Traditional rocket computers mostly use FPGA+DSP architecture. In order to adapt to different peripherals such as navigation systems, steering gear systems, remote control telemetry systems, surveillance cameras, etc., different external interfaces are designed. The entire rocket electronics system requires multiple processors or The controller has complex structure, heavy weight, large cost and volume, and at the same time, the reliability is reduc...

Problems solved by technology

[0003] The traditional rocket-borne computer mostly adopts the FPGA+DSP architecture. In order to adapt to different peripherals such as navigation systems, steering gear systems, remote control telemetry systems, and surveillance cameras, different external interfaces are designed. The entire rocket electronics system requires multiple processors or The controller has complex structure, heavy weight, large cost volume, etc., and the reliability is reduced, which is increasingly unable to meet the development needs of low-cost civil and commercial aerospace in the future.
