基于国产SoPC平台的外部总线的设计与实现

可重构的SoC(system-on-a-chip)是嵌入式系统发展的一个重要方向,它不仅可以达到较高的性能而且更加的灵活.介绍了一种国产的SoPC(System on a Programmable Chip)平台,并基于此平台提出了一种用于重构计算的外部总线结构.通过该总线,可以通过改变不同的IP(intellectual property)核来组成新的系统.同时回顾总结了部分动态可重构的步骤并完成了一个完整的系统,最后给出了可重构系统的测试结果.

Design and Implementation of the Peripheral Bus Based on Reconfigurable Platform

Reconfiguration system-on-a-chip(SoC) is an important trend of embedded system.It is not only to achieve the higher performance but also flexible enough.In this paper,a SoPC(System on a Programmable Chip) platform is introduced and a new kind of peripheral bus used for reconfigurable computing is proposed.Using this peripheral bus,we can form a new embedded system easily by changing different intellectual property(IP) cores in a short time.This paper also overviews the process of partial dynamic reconfiguration and accomplishes a reconfigurable system.Finally,we give a result of the reconfiguration time in embedded systems.
