This paper discussed several key issues of real - time cluster parallel system and the applying to real - time information processing and controlling of multi sources , on the b - asis of research on the first real - time cluster computer system in our country 本文結合作者在課題設計期間參與研究與開發(fā)的國內(nèi)首套實時集群計算機系統(tǒng)項目(該項目獲國家科技部2001年度創(chuàng)新基金01c26226111003資助) ,首次較全面地論述了實時集群計算機系統(tǒng)的關鍵技術及其在實時多源信息處理與控制方面的應用。
As we analyze the international progress direction of high reliability system , which usually composed by parallel system and tolerance system , for example , on aviation , on industry control , on spaceflight and other aim of military , we need to develop a highly reliable system according to the theory of embedded system , parallel dispose and real time system 分析當前國內(nèi)外的環(huán)境,某些特殊領域需要高可靠性的系統(tǒng),高可靠性體現(xiàn)在數(shù)據(jù)容錯處理,容錯處理等方面,典型應用領域包括航空航天,軍事領域,工業(yè)控制等方面。因此本課題將結合嵌入式系統(tǒng),容錯處理技術,實時系統(tǒng)原理,闡述如何開發(fā)高可靠性的容錯實時系統(tǒng),并提出一套完整的解決方案作為示例。
Consisted of adsp21060 - sharc parallel 32 - bit floating point dsp , distributed parallel system and shared bus parallel system will satisfy signal processing tasks in sar application fields . this paper discusses range - doppler ( rd ) algorithm and two - dimension detachable algorithm in the side - looking model in synthetic aperture radar ( sar ) respectively , then studies the realization on multi - chips adsp21060 sharc dsp system 以美國ad公司的adsp21060 - sharc (超級哈佛結構計算機)系列并行32位浮點dsp構成的分布式并行系統(tǒng)和共享總線式并行系統(tǒng),可以滿足綜合孔徑雷達( sar )應用領域的信號處理任務。
