摘要
宽带无线接入(BWA)是当今通信信息产业中最为先进和发展最快的技术,它可以满足下一代通信系统中人们对于语音、数据、多媒体三重业务的需要。在提出了一种基于ADI高性能双核DSP Blackfin561架构的宽带无线接入系统终端硬件设计方案后,对硬件设计思想进行了阐述,随后详细介绍了基于以太网控制器Lan9115的以太网接口设计及其驱动,同时给出了CPLD中串并转换时序逻辑仿真图。该设计方案在实际的样机应用中表现出了良好的性能,各项指标均满足系统设计要求,达到了预期的效果。
BroadBand Wireless Access （BWA） is the most Advanced and fast developed technology in current communication industry, it can meet people＇s needs of triple play： Speech. Data. Multimedia in the next generation communication system. In this paper, present a hardware design scheme for BWA system terminal based on ADI high performance DSP--Blackfin561, and mainly focuses on the Ethernet interface design based on the Ethernet controller--Lan9115, corresponding to software driver and CPLD timing sequence control in the system. At same time, present the CPLD--based simulation results of data parallel--to--series and series--to--parallel transformation. After being measured, the system depending on our scheme exhibits perfect performance, and all specifications satisfy the design requirements.
