UHF读写器设计中的FM0解码技术
<DD> 针对UHF读写器设计中，在符合EPC Gen2标准的情况下，对标签返回的高速数据进行正确解码以达到正确读取标签的要求，提出了一种新的在ARM平台下采用边沿捕获统计定时器数判断数据的方法，并对FM0编码进行解码。与传统的使用定时器定时采样高低电平的FM0解码方法相比，该解码方法可以减少定时器定时误差累积的影响；可以将捕获定时器数中断与数据判断解码相对分隔开，使得中断
基于DSP与FPGA的多视频通道的切换控制
为了扩大监控范围，提高资源利用率，降低系统成本，提出了一种多通道视频切换的解决方案。首先从视频信号分离出行场信号，然后根据行场信号由DSP和FPGA产生控制信号，控制多路视频通道之间的切换，从而实现让一个视频处理器同时监控不同场景。实验结果表明，该方案可以在视频监控告警系统中稳定、可靠地实现视频通道的切换。
