| 摘 要： | ADSP2106X无法与采用地址/数据总线复用形式的接口芯片直接连接。本文在介绍ADSP2106X外部总线口功能特点和相应信号作用的基础上,以地址/数据总线复用形式的可编程并行接口芯片8155H为例,设计了与ADSP2106X的接口电路,详细说明了该接口电路的组成原理与工作过程。这一方法对设计其它采用地址/数据总线复用形式的芯片与DSP的接口也具有很好的实用价值。

| Abstract: | ADSP2106X can not be connected direct to the interface chips that adopt address and data multiplex mode bus.On the basis of briefing the function characteristics and corresponding signal actions of external bus port of ADSP2106X,taking the 8155H chip that is a programmable parallel interface adopting address and data multiplex mode bus as an example,an interface circuit between the 8155H and ADSP2106X is designed,and the composing principle and work process of this circuit are explicated. This method has good reference value for designing the interface circuits between other chips adopting address and data multiplex mode bus and DSP. |
