摘　　要：为了方便不同的IP(intellectual property)核的连接,针对AHB与WISHBONE这两种总线的广泛性,提出了一种双向AHB-WISHBONE总线桥的设计方法。介绍了这两种总线协议的特点和结构,阐述了AHB-WISHBONE总线桥的设计结构和实现方法。该方法难点在于AHB总线突发传输的实现,且支持多个AHB设备与多个WISHBONE设备之间的相互访问。使用Verilog语言在modelsim工具下进行了验证,仿真结果表明总线桥的设计符合要求。To make the connection convenient among different IP （intellectual property） cores, design of the bidirectional bus bridge is proposed in view of the universality of AHB and WISHBONE bus. Firstly, the characteristic and structure of the two buses is described, and then a conclusion of the designing and implementing technique of the bidirectional bus bridge is reached based on it. The special difficulties lie in the implementation of the burst transmission of the AHB bus, and the supporting of the mutual access between multiple AHB and multiple WISHBONE. Finally validation is implemented utilizing Verilog languadge under the environment of modelsim. Simulation result shows that design of this bus bridge conform to the requirements.
