系统可重构技术是满足电子系统实时性和灵活性要求的先进技术。通过对FPGA结构和重构方式的分析,说明可重配置FPGA器件是可重构系统的良好载体,并提出准动态重构的概念。根据现有应用,提出了基于FPGA的可重构系统面向中低端应用的通用微处理器+FPGA型和面向高端应用的处理器集成型即可编程片上系统两种基本结构模式,并对其应用加以展望。
System reconfigurability technology is advanced technology that meets the real-time and flexibility requirements of electronic systems. Through the analysis of the FPGA structure and reconstruction mode, it shows that the reconfigurable FPGA device is a good carrier of reconfigurable system and proposes the concept of quasi-dynamic reconfiguration. According to the existing applications, the FPGA-based reconfigurable system for general-purpose low-end applications for the microprocessor + FPGA and high-end applications for the processor-based programmable system-on-chip architecture of the two basic structure, and its Application to look forward.
