【摘要】 针对传统的定位终端系统结构和设计上的缺陷,利用Nios软核处理器集成度高、配置灵活等特点,结合GPS和GSM模块,提出了一种基于SOPC技术的双定位终端系统设计方案。该方案通过SOPC Builder开发工具将Nios处理器、存储器和接口等组件快速地嵌入到高密度FPGA中,采用单个控制芯片完成了人机交互模块、控制模块和通信模块等功能,实现了高精度的实时定位功能。实践表明:该系统具有极好的灵活性、扩展性和通用性,且系统结构紧凑、功耗较低。更多还原

【Abstract】 Aiming at the shortcoming of design and architecture of the traditional positioning terminal system, a design scheme of dual positioning terminal system based on SOPC was proposed, which was integrated with GSM and GPS and made use of the advantages of high integration rate and flexible configuration of Nios soft CPU core. Nios soft CPU core, memory and all kinds of interface were embedded in a high density FPGA by SOPC Builder. The scheme accomplished man-machine interactive function, control and com-munication by using single control chip, and realized high precision real-time positioning function. The experimental result indicates that the system has the characteristics of well flexibility, extensibility and generality, compact conformation and low power.更多还原
