基于SOPC的外设器件共享总线方法的研究

Research on the Method for the Peripheral Devices Shared Bus Based on SOPC

介绍了Altera公司的可编程片上系统(SOPC)以及Avalon总线的概念,研究了基于SOPC系统的片内总线型外设共用Avalon总线的设计方法,实现了外设共享Avalon总线的电路设计,并对所设计的总线接口的功能进行了验证。验证结果表明Avalon总线功能强大,为用户提供了非常友好的接口,使得系统搭建中的一些细节问题得到屏蔽,大大减轻了系统搭建的工作量。

This paper introduces Altera＇s SOPC and the concept of Avalon bus, studies the design method for peripherals of bus type on-chip based on SOPC shared Avalon bus, realizes the circuit design of peripherals to share Avalon bus, and verifies the interface functions of the designed bus. The results show that the Avalon bus is powerful; it provides a very friendly interface for users, shields some of the details during the system setting up, and greatly reduces the workload of setting up the system.
