基于差异和模块重构技术的动态可重构设计
A Dynamic Reconfiguration Method Based on Difference and Model Structure
-
摘要: 传统的动态重构方案分为基于差异的部分重构和基于模块的动态重构,两种方案存在各自的应用范围.提出了一种将两种方案的优势结合的设计理念,既提高了重构速度又为系统的升级提供了可扩展平台.具体设计了一个由4种不同的超前进位加法器构成的动态可重构系统,通过对系统的布局仿真,对得到的数据进行分析得到了重构速度和系统的资源利用率.Abstract: The traditional dynamic reconfiguration schemes are divided into the Difference-based method and the Model-based method, both of which are limited into specific situation. This paper introduces a combination of the above two methods and successes in speeding up the reconfiguration process and allowing for extendibility. A series of CLAs(Carry Look-ahead Adder) based on this new method were designed to test and verify the speed and resource utilization.
