  • 板级光互连协议研究与FPGA实现

    随着集成电路频率的提高和多核时代的到来,传统的高速电互连技术面临着越来越严重的瓶颈问题,而高速下的光互连具有电互连无法比拟的优势,成为未来电互连的理想替代者,也成为科学研究的热点问题。目前,由OIF(Optical Intemetworking Forum,光网络论坛)论坛提出的甚短距离光互连协议,主要面向主干网,其延迟、功耗、兼容性等都不能满足板间、芯片间光互连的需要,因此,研究定制一种适用于板级、芯片级的光互连协议具有非常重要的研究意义。 本论文将协议功能分为数据链路层和物理层来设计,链路层功能包括了协议原语设计,数据帧格式和数据传输流程设计,流量控制机制设计,协议通道初始化设计,错误检测机制设计和空闲字符产生、时钟补偿方式设计;物理层功能包含了数据的串化和解串功能,多通道情况下的绑定功能,数据编解码功能等。 然后,文章采用FPGA(Field Programmable Gate Array,现场可编程门阵列)技术实现了定制协议的单通道模式。重点是数据链路层的实现,物理层采用定制具备其功能的IP(intellectual Property,知识产权)——RocketIO来实现。实现的过程中,采用了Xilinx公司的ISE(Integrated System Environment,集成开发环境)开发流程,使用的设计工具包括:ISE,ModelSim,Synplify Pro,ChipScope等。 最后,本文对实现的协议进行了软件仿真和上扳测试,访真和测试结果表明,实现的单通道模式,支持的最高串行频率达到3.5GHz,完全满足了光互连验证系统初期的要求,同时由RocketIO的高速串行差分口得到的眼图质量良好,表明对物理层IP的定制是成功的。

  • 射频集成电路设计John Rogers(Radio Freq

    Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign radio frequency (RF) communications integrated circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The circuits usually used have evolved through experience, without asatisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

  • wp379 AXI4即插即用IP

    In the past decade, the size and complexity of manyFPGA designs exceeds the time and resourcesavailable to most design teams, making the use andreuse of intellectual Property (IP) imperative.However, integrating numerous IP blocks acquiredfrom both internal and external sources can be adaunting challenge that often extends, rather thanshortens, design time. As today's designs integrateincreasing amounts of functionality, it is vital thatdesigners have access to proven, up-to-date IP fromreliable sources.

  • PLD对FPGA数据加密

    SRAM-based FPGAs are non-volatile devices. Upon powerup, They are required to be programmed from an external source. This procedure allows anyone to easily monitor the bit-stream, and clone the device. The problem then becomes how can you effectively protect your intellectual property from others in an architecture where the part is externally programmed?
