摘　　要：基于现场可编程门阵列(FPGA)动态可重构系统可以实时重构硬件,提高计算的灵活性、自适应能力以及自优化能力。使用局部动态重构不仅能够保证重构过程中主系统的正常实时运行,而且可以减少重构过程的时间。然而,现有的基于FPGA的平台往往受到各种物理限制使得局部动态重构实施过程变得困难。文章介绍了目前FPGA动态局部重构技术面临的各种问题和解决方案,并对该技术的发展趋势给出了展望。Dynamically reconfigurable FPGA-based systems offer a new kind of flexibility such as ondemand computing, self-adaptation and self-optimization capabilities by restructuring the hardware at run-time. Using partial dynamic reconfiguration allows the main system to run uninterrupted during the reeonfiguration process in addition to the reduced time for the reconfiguration process. However, existing FPGA-based platforms are hampered by physical restrictions limiting the practicability of partial reconfiguration. This paper gives a detailed introduction to the problems and solutions of FPGA-based partial reeonfiguration technology and future work in the research field is also pointed out.
