摘要摘要 摘要 摘要 近年来，一种新的系统实现方式一可重构系统受到学术界的关注。它采用 动态电路重构技术，在运行时根据需要动态改变系统的电路结构，从而使系统 既有采用硬件优化所能达到的高速度和高效率，又能像软件那样灵活可变、易 于升级。随着FPGA的一些改进，可重构系统投入实际应用成为可能。在很多对 运算速度和灵活性都有很高要求的应用得到广泛的采用。 动态部分重构技术充分地利用了FPGA芯片提供的可重构功能，更好地推动 了可重构计算的发展，正成为当前国内外的研究热点。它减小了配置位流下载、 重构FPGA芯片的时间，节省硬件资源，有效地提高了系统的整体性能。 本文对基于模块和基于差异两种动态部分可重构实现技术作了剖析，搭建 了硬件开发平台，针对ISE用于开发动态部分可重构系统中存在的不足，设计并 实现了动态部分可重构系统框架自动生成工具，最后应用这个工具在硬件开发 平台上设计并实现了可应用于CRC／IP分组首部校验的动态部分可重构系统，并 对实现的结果作了分析。 关键词：FPGA，Virtcx-II，可重构计算，动态部分可重构 AbstractAbstract Abstract Abstract In the recent years，the reconfigurable system，a new method of system implementation，is widely noticed by the academic．It adopts the technology of reconfiguratinn of circuitry at runtime．When it is rtmning，the structure of the circuitry call be dynamically modified on demand．It has not only the high speed and the high efficiency as the optimized hardware systems．The reconfigurable system has much attractive prospects of applicafion on those situations where both the speed and flexibility are important．As the development ofthe technology ofthe programmable logic devices and some improvements on the circuitry-design methodology,nOW it is possible to utilize the reconfigurable system to the practical applications． Partially Run-Time Reconfiguration(Partially RTR)is becoming concerned filed，domestically and abroad．It takes advantage of the Partial reconfigurable characteristics in FPGA devices and promotes the development of reconfigurable computing．It solves the problem of taking too much time to configure the FPGAs． The Partially RTR saves hardware resources as well as improving the system performance． This dissertation analyzes two flows for partial reconfiguration：module based and difference based．As to the shortcomings of ISE，we have developed mainframe-generator for Partially Run-time Reconfigurable System as well as the hardware development platform，on which Partially Run·time Reconfiguration System for CRC／IP checking has been achieved by using the tools．After that，th
