本文讨论的四种常用FPGA/CPLD 设计思想与技巧：乒乓操作、串并转换、流水线操作、数据接口同步化，都是FPGA/CPLD 逻辑设计的内在规律的体现，合理地采用这些设计思想能在FPGA/CPLD 设计工作种取得事半功倍的效果。-This article discusses the four commonly used FPGA/CPLD design ideas and techniques: ping-pong operation, strings, and conversion, pipelined, data synchronization interfaces, are FPGA/CPLD logic design of the internal laws of the embodiment of rational use of these design concepts can be FPGA/CPLD design of the kinds of achieving a multiplier effect.
