The both can not run without parallel processing technique 這兩個方面都離不開并行處理技術。
Consequently , we can develop the parallel arithmetic technique in image processing or image compression . parallel processing technique deals with many aspects 并行算法和軟件的許多研究方面尚處于探索階段,技術上還不成熟。
At the same time , the unlimitedly demand for the performance of computers lead to the appearance and great developments of parallel processing technique 另一方面,在高尖端科技領域內,并行處理技術的出現和蓬勃發展,使得該技術成為現代高性能計算機中最關鍵技術之一。
( 7 ) mathematical morphology is one of the new subjects studying the structural feature of digital image morphology and fast parallel processing technique . the structural analysis and feature extraction is made by morphological transformation in object image 7 、數學形態學是研究數字影像形態結構特征與快速并行處理方法的理論,是通過對目標影像的形態變換實現結構分析和特征提取的。
Parallel processing technique deals with many aspects . it includes hardware technique , parallel architectures , parallel operating system , parallel languages , parallel compiler , parallel software , parallel algorithm , etc . but the current international situation is that the development of parallel algorithm is far more behind other architectures . the most dominating appearances are the lacks of corresponding software , the rational distributing of tasks , the communications and the synchronization 雖然使用范圍很廣,但目前國內外的并行算法應用研究明顯地滯后于其體系結構的發展,許多方面尚處于探索階段,技術上還不是很成熟,其中最主要的表現就是配套軟件的欠缺,任務合理分配的問題和通信與同步的問題。
