基于FPGA电路重构技术的电子系统设计

Electronic System Design Based on Technology of FPGA Circuit Reconfiguration

文中通过应用实例详细地介绍FPGA电路重构技术。在充分了解FPGA的PS配置模式时序的基础上,用单片机AT89C51模拟实现PS配置时序,从而实现FPGA电路重构技术。文中给出了详细的系统硬件电路图和单片机程序流程图。为了说明电路重构技术,通过开关可以选择系统的两种不同的系统结构,分别是数字显示电子钟和18路电子抢答器,因而实现了系统硬件电路的重构。

Using applied example,the technology of FPGA circuit reconfiguration was introduced in detail in this paper. According to fully understanding PS configuration timing,AT89C51 simulates and realizes PS configuration timing,and the system realizes the technology of FPGA circuit reconfiguration. Detailed system hardward circuit diagrams and MCU program flow chart are provided in this paper. To show the technology of circuit reconfigurafion, via two switches, we can seleet two different system architectures of the system, which are digital-displaying electronics clock and 18-channels electronics snagging-answer device for intelligence contesting respectively,as a result, the system realizes reconfiguration of hardware of the system.
