摘要
在相关跟踪处理器的研制中,利用PCI主设备的直接内存存取(DMA)传输高速图像数 据到内存,采用PCI从设备方式将板上的I/O映射为主机I/O,使系统的I/O性能达到16MB/s,满足相关跟踪处理器对I/O性能的要求。
In development of correlation tracking processor, transmitting high-speed image data to memory with direct memory access for PCI master equipment and mapping on-board I/O as master computer I/O with PCI slave, thus the I/O performance of the system can attain 16-Mbit/s and the demands of the correlation tracking processor for I/O performance can be fulfilled.
