学术论文  基于FPGA的PCI总线接口控制器的设计

为了满足外围设备之间、外围设备与主机之间高速数据传输，Intel公司于1991年提出PCI(Peripheral Component Interconnect)总线的概念，即周边器件互连。因为PCI总线具有极高的数据传输率，所以在数字图形、图像和语音处理以及高速数据采集和处理等方面得到了广泛的应用。本论文首先对PCI总线协议做了比较深刻的分析，从设计 ...

PCB相关  PCB被动组件的隐藏特性解析

PCB 被动组件的隐藏特性解析传统上，EMC一直被视为「黑色魔术（black magic）」。其实，EMC是可以藉由数学公式来理解的。不过，纵使有数学分析方法可以利用，但那些数学方程式对实际的EMC电路设计而言，仍然太过复杂了。幸运的是，在大多数的实务工作中，工程师并不需要完全理解那些复杂的数学公式和存在于EMC规范中的学理 ...
