| 摘 要： | 针对DOCSIS上行发射器的高功耗问题,通过建立DOCSIS上行信道多电缆调制解调器(CM) 突发传输和功耗模型,提出了一种基于时分多路接入(TDMA)方式接入自适应休眠的低功耗上行发射器的设计方法.典型网络环境下的实验结果表明,所提出方法能使DOCSIS上行发射器降低51.37%的功耗.该低功耗DOCSIS上行发射器已经成功应用于符合EuroDOCSIS1.1 规范的支持双向有线电视点播的CM SOC平台中,并表现出优良的低功耗性.

| Abstract: | To reduce the high power consumption of DOCSIS upstream transmitters,the burst transmission and the power con- sumption for multi-cable modem(CM)systems were modeled.Based on the proposed models,an adaptive sleep low pow- er VLSI architecttLre for DOCSIS upstream transmitters was designed.The test results show that 51.73 % of the power of a upstream transmitter will be reduced by the proposed architecture under the typical network environment.The proposed low power transmitter was successfully integrated in... |
