AMBA总线技术在片上系统(SOC)集成设计中的应用

Design of SOC System Structure Based on AMBA Bus

在SOC设计中,AMBA总线得到广泛的应用。AMBA总线由高速总线AHB/ASB(Advanced H igh-performance Bus)和低速总线APB(Advance Peripher-al Bus)2种总线机制组成,实现R ISC处理器、IP核和外设集成。本文介绍了AMBA总线在SOC设计中的集成设计,并通过16C550串口通讯IP核集成设计例子,展示如何利用AMBA总线的APB总线接口集成IP核,搭建一个SOC系统。

With the development of SOC design technology, AMBA bus is widely applied. The AMBA bus consists of AHB/ASB （Advanced High-performance Bus） and APB （Advance Peripheral Bus）. RISC processor,IP and peripheral apparatus are integrated by AMBA bus. The design of system integration using AMBA bus, the IP integrated design method based on APB bus are introduced, and then through the example of 16C550 communication IP integrated design, how to build a SOC system using AMBA bus is demonstrated as well.
