H.264/AVC是国际电信联盟与国际标准化组织/国际电工委员会联合推出的活动图像编码标准，简称H.264。作为最新的国际视频编码标准，H.264/AVC与MPEG-4、H.263等视频编码标准相比，性能有了很大的提高，并已在流媒体、数字电视、电话会议、视频存储等诸多领域得到广泛的应用。 本论文的研究课题是基于H.264/AVC视频编码标准的CAVLC(CONTEXT-based Adaptive Variable Length Coding，基于上下文的自适应可变长编码)编码算法研究及FPGA实现。对于变换后的熵编码，H.264/AVC支持两种编码模式：基于上下文的可变长编码(CAVLC)和基于上下文的自适应算术编码(CABAC，CONTEXT-based Adaptive BinaryArithmetic Coding)。在H.264/AVC中，尽管CAVLC算法也是采用了VLC编码，但是同以往标准不同，它所有的编码都是基于上下文进行。这种方法比传统的查单一表的方法提高了编码效率，但也增加了设计上的困难。 作者在全面学习H.264/AVC协议和深入研究CAVLC编码算法的基础上，确定了并行编码的CAVLC编码器结构框图，并总结出了影响CAVLC编码器实现的瓶颈。针对这些瓶颈，对CAVLC编码器中的各个功能模块进行了优化设计，这些优化设计包括多参考块的表格预测法、快速查找表法、算术消除法等。最后，用Verilog硬件描述语言对所设计的CAVLC编码器进行了描述，用EDA软件对其主要功能模块进行了仿真，并在Cyclone II系列EP2C20F484的FPGA上验证了它们的功能。结果表明，该CAVLC编码器各编码单元的编码速度得到了显著提高且均能满足实时通信要求，为整个CAVLC编码器的实时通信提供了良好的基础。

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.

FeaturesThe following standard features are provided.• Choice of RTOS scheduling policy1. Pre-emptive:Always runs the highest available task. Tasks of identical priorityshare CPU time (fully pre-emptive with round robin time slicing).2. Cooperative:CONTEXT switches only occur if a task blocks, or explicitly callstaskYIELD().• Co-routines (light weight tasks that utilise very little RAM).• Message queues• Semaphores [via macros]• Trace visualisation ability (requires more RAM)• Majority of source code common to all supported development tools• Wide range of ports and examples

ICA is used to classify text in extension to the latent semantic indexing framework. ICA show to align the CONTEXT grouping structure well in a human sense [1], thus can be used for unsupervised classification. The demonstration shows this on medical abstracts (MED dataset), that uses BIC to estimate the number of classes and produces keywords for each class. The icaML algorithm is used.

Draak is a multi-language, macro compiler, meaning all syntax and code generation is defined in a single file. Draak is a single binary that is able to compile any CONTEXT free language (like C, Pascal, Java) for any platform with only 1 file. Draak Compiler是一个多语言，宏编译器，可以在一个单独的文件中定义所有的语法和代码生成。Draak 是一个单独的二进制文件，可以在任意平台上只使用一个文件来编译任何上下文无关的语言（类似 C, Pascal, Java）。
