项目摘要

PROPOSAL NO: 0429979INSTITUTION: University of Minnesota-Twin CitiesPRINCIPAL INVESTIGATOR: Parhi, KeshabTITLE: Design of High-Speed DSPTransceivers for Ethernet over CopperAbstract:The server speed should always be an order of magnitude higher than the desktop speed. Growing use of gigabit ethernet on desktops and laptops requires availability of 10-gigabit over copper in data centers. These must exploit use of existing or new copper cables, and must be cheaper than their fiber based competitors. This project will address architectural design aspects and VLSI implementation aspects of the digital signal processing components of a 10-gigabit per second ethernet transceiver over copper. The challenges in design of these systems are many. At the system level, to achieve the required speed, what should be the baud rate and modulation scheme? Should one use precoding at the transmitter or equalization at the receiver? Should one use low-density parity check codes? How can one implement a 7000-tap based receiver, necessary for cancelling near end cross talk and echo for the cables, with lower power consumption? What receiver architectures are more suitable for meeting the speed requirements? What are the best solutions for implementing low-density parity check codes at 10 gigabits per second? Answers to these questions will be sought. Novel modulation schemes will be studied by hardware codesign techniques and the best architecture of a system with least area and power consumption will be sought. Availability of 10-gigabit per second data at data centers and desktops will significantly reduce the cost of deployment and increase the speed of internet access.

提案编号：0429979INCINANTITITION：明尼苏达大学 - 两国大学城市调查员：Parhi，Keshabtitle：高速dsptransceivers for copperabstract上的高速dsptransceivers的设计：服务器速度应始终比桌面速度高。在台式机和笔记本电脑上使用千兆以太网的使用日益增加，需要在数据中心的铜上使用10 gigabit。这些必须利用现有或新铜电缆的使用，并且必须比基于纤维的竞争对手便宜。该项目将解决数字信号处理组件的架构设计方面和VLSI实现方面，即铜上10 gbabit的每秒以太网收发器。这些系统设计的挑战很多。在系统级别，为了达到所需的速度，波特率和调制方案应该是什么？应该在发射器上使用预编码或接收器的均衡吗？应该使用低密度平价检查代码吗？一个人如何实现基于7000-TAP的接收器，这对于取消较低功耗的电缆近端交叉谈话和回声是必需的？哪些接收器架构更适合满足速度要求？以每秒10千兆位实施低密度平价检查代码的最佳解决方案是什么？将寻求这些问题的答案。新颖的调制方案将通过硬件代码设计技术研究，并且将寻求面积最少和功耗的系统的最佳体系结构。在数据中心和台式机上每秒10 gabit的可用性将显着降低部署成本并提高互联网访问的速度。
