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范的领域,在单一芯片上采用更合理的设计工艺、集成更多的逻辑功能,已经成为技术发展趋势。介绍了一套基于Altera公司的NIOS嵌入式CPU开发的多路电话计费系统。该系统充分体现了SOPC(System On Programmable Chip)的设计理念,采用Altera公司的Cyclone芯片实现了多路电话的计费、管理等功能,获得了最优的性价比。从硬件设计与软件设计2个方面介绍了系统的开发流程,尤其是对片内资源的配置部分做了详细地说明。With the great growth of the CPU performance,the design of embedded system comes into a wider field.It has became a development trend of embedded technology that is using more reasonable designtechnics and integrating more logical functions on a programmable chip.This paper introduces a multichannel phonebillingsystem,which based on the NIOS embedded CPU in Altera Corporation.This system appeares the SOPC′s design idea, accomolishes the functions including multichannel phone′s bill and manage with single Altera Cyclone chip, achieves the best propotion between performance and price.This paper introduces the development flow from two aspects:software and hardware,especially introduces detailedly the configuration option of onchip resource.
