| 摘 要： | 介绍了一种应用于PDA系统中的可支持多种类型MCU的接口的设计与实现。采用对不同MCU信号总线使用独立处理通道的设计思想，设计接口支持多达八大类的MCU，同时达到其高速的要求(最高100M)。着重介绍了Motorola的MC68K2接口，它具有一定的共性。对所设计的电路进行了仿真，得到了很好的仿真结果，并通过了FPGA的验证。

| Abstract: | A multi-MCU supporting MCU interface which is applied mainly in personal digital assistant(PDA)system is presented in the paper.The strategy of design of this interface circuit is that the independent signals process channels will be setup for different MCUs.The interface will be designed to support eight types of MCUs and work at a high clock(Maximum is 100M).Only two kinds of interfaces are described detailedly,MC68K2 interface and Indirect interface,the previous one has some common characteristics with other interfaces,the latter one is a very particular interface using a few amount of lines.The circuit has been simulated and a desirable result is achieved.The design has been implemented on a FPGA. |
