无线通信 UHF读写器设计中的FM0解码技术

   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 ...

ARM ARM手机MID平板方案详解

ARM核心是主控SOC中的重要部分,系统的日常应用都由ARM核心来完成,因此ARM核心的效能很大程度上跟用户体验有关。ARM公司一般用DMIPS/MHz来标称ARM核心的性能。DMIPS是Dhrystone Million Instructions executed Per Second的缩写,反映核心的整数计算能力。但Dhrystone算法代码本身比较叫,可以完全放到Cache中执行,因此 ...

可编程逻辑 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...
