The Memory Management and Optimization of PCI Driver

摘要：

Various memory allocation methods provided by PCI driver are analyzed and compared, the factors that affect the driver transmission performance are found and effective optimization program for the DMA transmission is made. In hardware configuration, please use the disk array to write to improve the computers disk speed. In programming, please use multi-thread approach, set ping-pong buffer, combined with multi-core thread parallel processing technology to improve the efficiency of PC machines. These measures have been used successfully in data acquisition system, and then a good DMA transmission performance is obtained.
