DMA(Direct Memory Access) technology is one of the best solutions which could meet the requirements of real-time and accuracy for information processing.
在此前提下,采用高速数据传输技术成为必然,DMA(直接存储器访问)技术就是较理想的解决方案之一,能够满足信息处理实时性和准确性的要求。
In order to meet the real-time processing requirement for the infrared sequential image processing and some algorithms such as image de-noising,non-uniformity correction,image adaptive dissection,image measurement and mathematic model resolving in a specific infrared imaging position system,an effective scheme for transferring and exchanging infrared image data by DSP DMA is proposed.
针对某红外成像定位系统对红外序列图像处理和诸如图像去噪、非均匀性校正、图像自适应分割、图像测量、数模解算等算法的实时性能要求,提出采用DSP DMA(存储器直接访问)方式处理系统中的转移和大量交换高效方案。
At last,a controlling system based on VRS51L3074 is presented,the output circuit is optimized,and the "Direct Memory Access(DMA)" output mode of display data is realized.
实现了显示数据以"直接存储器访问(DMA)"方式输出。
