【摘要】 介绍了用于某型号产品的多通道高速同步数据采集及快速图形显示技术。该技术的核心是以一块卡的内触发信号为基准,启动其余卡的触发信号,在设计中每一个通道均配置了独立并行的前置处理、A/D转换及大容量的RAM。而图形显示的优化算法确保了显示效果和显示速度均可达到令人满意的程度。更多还原

【Abstract】 This paper introduces the technique of synchronized high-speed data gather for multi-channels and fast gra-phics display of the gathered data,which has applied into practice.The core of this technique is using the internal trig-ger signal of one card as the benchmark to startup the trigger signal of other cards.Every channel has been configured its own independent parallel preprocessor,A/D converter and bulky RAM in the design.The optimized algorithm of graphics display of the gathered data insured the effect and speed of display could be perfect.更多还原
