从总线时间比的角度出发分析了总线时序实现的难易程度。通过对时间方程的分析 ,讨论了严格同步的时钟系统、固定相移的同步时钟系统、动态调节的同步时钟系统的总线时序 ,并设计出一种时钟相位可调总线时序。在此基础上实现了一种基于GTL逻辑的高速同步总线测试系统 ,并通过实际测试证明了对三种同步时钟系统总线时序分析的正确性 ,结论为各种实际高速同步总线的时序设计提供了很好的参考价值 From the aspect of bus time ratio, it analyzes the difficulty of bus timing realization. By analyzing the time equations, the strict synchronization clock system, the synchronous clock system with fixed phase shift and the bus timing of the dynamically adjusted synchronous clock system are discussed, and a bus clock sequence with adjustable clock phase is designed. Based on this, a high-speed synchronous bus test system based on GTL logic is realized, and the correctness of bus timing analysis of the three kinds of synchronous clock systems is proved through actual tests. The conclusion provides the timing design of various high-speed synchronous buses Very good reference value
