摘　　要：通过外部总线口扩展外部存储器和接口是构成ADSP2106X应用系统时最基本、最重要的设计。在深入分析ADSP2106X外部总线口功能特点和相应信号作用的基础上,详细讨论了在给ADSP2106X扩展片外存储器和接口时应考虑的地址分配和地址译码方法等问题,并给出了具体设计方法实例。实验表明,提出的设计方法正确灵活,可扩展性好。这些方法对设计ADSP2106X应用系统以及其他DSP应用系统都具有很好的参考价值。It＇s the fundamental and foremost design for constituting an ADSP2106X application system to expand external memories and interfaces by the external bus port of ADSP2106X. On the basis of analyse in depth the function characteristics and corresponding signal actions of external bus port of ADSP2106X, this paper discussed the problems such as address distribute and address coding needed to be considered as expanding external memories and interfaces for ADSP2106X, and presents the concrete design examples. By experiments, it has been showed that these methods are right and flexible, and have good expansibility. These methods have good reference value for designing ADSP2106X application systems and other DSP application systems.
