Design And Implementation Of Airborne/Satellite Large Image Parallel Processing Platform

The airborne/satellite task platform is oriented to key information acquisition,and there are huge data and request real-time information extraction.Such image data processing and conventional information processing platforms have the following differences: 1)There are various kinds of airborne/satellite sensors,which need real-time monitoring of airborne/satellite;2)Rich type of airborne/satellite data and high energy efficiency requirements for data processing;3)The airborne/satellite task platform is designed for multiple applications,requiring real-time analysis of large amounts of data and extracting key information to meet the actual needs.This paper according to the diversity of airborne sensors/satellite mission platform,Large data of airborne/satellite image parallel processing algorithm hardware requirements were analyzed and the building in conformity with the general requirements of airborne/satellite data parallel processing platform.This paper puts forward a basic airborne/satellite image parallel structure model,in airborne/satellite data parallel processing platform of project implementation to the practice of the basic framework.Secondly,according to the parallel structure model,the basic scheme of the hardware engineering design of airborne/satellite big data parallelization processing is given and the key technologies are studied.In particular,a lot of early engineering verifications is carried out on power supply,clock,interface,core processing unit and other key problems.And then combined the actual project requirements,carried out airborne/satellite data parallel processing hardware design,validation,airborne/satellite respectively for a image data parallel processing main function verification,and the key performance such as signal integrity test,function verification and performance test results are given.This article focuses on airborne/satellite mission platform image data parallel processing algorithm for hardware requirements.At the same time to build a kind of airborne/satellite image data parallel structure model,and combined with the actual engineering project,through the design,function verification,key performance test,a preliminary inspection of the design of environmental adaptability,and applied in the actual project.
