摘要
随着CPU性能的大幅提升,嵌入式系统的设计已经进入了更广泛的领域。在单一芯片上采用更合理的设计工艺、集成更多逻辑功能的SOC(片上系统)设计方式,已经成为了一个技术发展的趋势。其中SOPC(片上可编程系统)因为它的软件可编程的特性,更为许多嵌入式系统开发人员所青睐。本文介绍了一套基于ALTERA公司的NIOSII嵌入式CPU开发的GPRS商品信息查询系统。该系统根据SOPC的设计思想,采用ALTERA公司的NIOSII软核处理器、Telit公司的GSM模块、Atmel公司的射频基站芯片集成设计实现了GPRS无线数据通信、非接触式IC卡读写、商品信息查询显示等功能。论文从硬件设计与软件设计两个方面介绍了系统的开发流程。
With the great growth of the processor＇ s performance, the Embedded system design comes into a wider field. SO（2 design has become a technology development trend of Embedded System that is using more reasonable design - technics and integrating more logical functions on a programmable chip. And many designers prefer the SOPC, because of SOPC＇s programmable characteristic. This paper introduced a GPRS CommodityInformation Query System, which is based on NIOS Ⅱ processor of Altera corporation. The system comprise Altera＇s NIOS Ⅱ processor, Telit＇ s GSM module and Atrnel＇ s RF base - station chip. Integrating the aboved realized the following founctions： GPRS wirless - communication, IC card＇ s reading and writing, commodity information＇ s querying and displaying, etc. This paper introduced the design flow from two aspects： software and hardware.
