摘　　要：在基于IP复用的SOC设计中,片上总线作为SOC系统集成的互连结构,负责各种移植IP之间的正常通信。片上总线作为各设计模块通信的桥梁,成为了SOC设计中的关键问题。基于AMBA Rev2.0 AHB-L ite总线协议,通过在存储控制器与AHB总线之间设计AMBA接口,实现系统专用网络据数处理引擎PE与嵌入式通用处理器ARM共享存储控制器对片外存储设备进行正常访问。On-chip bus works as the interconnection of integrated system in SOC design based on IP reuse technology,it is in charge of the normal communication between various portable IP cores.As a bridge of communication between various modules,on-chip bus becomes a key issue in SOC design.This paper,based on AMBA Rev2.0 AHB-Lite bus protocol,introduces a method of designing an AMBA interface between memory controller and AHB bus.As a result,both of system-specific network Processor Engine（PE）and general purpose embedded processor（ARM）can access to off-chip external memory by sharing this memory controller.
