The results indicate that the serial and parallel optimization for fft , phase compensation and matrix transpose has the most significance for sar imaging performance 分析结果认为,对sar成像处理的优化,主要是对fft 、相位补偿运算和矩阵转角运算等3类典型运算的串行优化和并行优化。
The fast dct algorithm not only can reduce the multiplication number , but also can combine the post - scaling and matrix transpose needed for fast dct with the quantization and scan processes , so as to speed up the whole mpeg encoder . in addition , the table - lookup fast quantization algorithm can further speed up the encoding process 本章提出的快速dct算法不仅减少了所需乘法的次数,而且变换后的后置乘法和矩阵转置过程可与量化和扫描相结合,进一步加速浙江大学博士学位论文整个mpeg编码过程。
Also , the relactions between the best block size for matrix transpose and the size and associativity of the processor ' s cache is formulized . for parallel optimization , several programming models available on a numa system , such as lightweight processes ( sproc ) , posix threads , openmp and mpi , are compared , and their speedup and coding complexity are analyzed 对于sar成像处理的并行优化,本文对比了在numa架构上可用的几种并行编程模型:轻量级进程、 posix线程、 openmp和mpi ,针对numa架构和sar成像处理的特点从加速比、编程复杂度等多个方面进行了讨论。
