摘要
使用BF531 DSP芯片提供的单组并行数据口(PPI接口)进行分时复用,实现在单PPI接口条件下的数字图像采集、处理与实时显示的设计方法,并对系统性能进行了分析。分析结果表明,使用时分复用单组并行数据口,可在保证图像处理实时性的前提下,有效降低系统硬件成本,简化了系统硬件结构。
The realization of a digital image acquisition processing and its real-time display sys- tem is describes, which has only one PPI in the DSP processor. The performance of the system is analyzed. The result indicates that sharing the only PPI in time division multiplexing way can reduce the cost of system hardware, and simplify the structure of system hardware without slowing down the system at the same time. It may be used as the basis and reference for the hardware design of embedded system.
