H.264/AVC是國際電信聯盟與國際標準化組織/國際電工委員會聯合推出的活動圖像編碼標準,簡稱H.264。作為最新的國際視頻編碼標準,H.264/AVC與MPEG-4、H.263等視頻編碼標準相比,性能有了很大的提高,并已在流媒體、數字電視、電話會議、視頻存儲等諸多領域得到廣泛的應用。 本論文的研究課題是基于H.264/AVC視頻編碼標準的CAVLC(CONTEXT-based Adaptive Variable Length Coding,基于上下文的自適應可變長編碼)編碼算法研究及FPGA實現。對于變換后的熵編碼,H.264/AVC支持兩種編碼模式:基于上下文的可變長編碼(CAVLC)和基于上下文的自適應算術編碼(CABAC,CONTEXT-based Adaptive BinaryArithmetic Coding)。在H.264/AVC中,盡管CAVLC算法也是采用了VLC編碼,但是同以往標準不同,它所有的編碼都是基于上下文進行。這種方法比傳統的查單一表的方法提高了編碼效率,但也增加了設計上的困難。 作者在全面學習H.264/AVC協議和深入研究CAVLC編碼算法的基礎上,確定了并行編碼的CAVLC編碼器結構框圖,并總結出了影響CAVLC編碼器實現的瓶頸。針對這些瓶頸,對CAVLC編碼器中的各個功能模塊進行了優化設計,這些優化設計包括多參考塊的表格預測法、快速查找表法、算術消除法等。最后,用Verilog硬件描述語言對所設計的CAVLC編碼器進行了描述,用EDA軟件對其主要功能模塊進行了仿真,并在Cyclone II系列EP2C20F484的FPGA上驗證了它們的功能。結果表明,該CAVLC編碼器各編碼單元的編碼速度得到了顯著提高且均能滿足實時通信要求,為整個CAVLC編碼器的實時通信提供了良好的基礎。

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是一個多語言,宏編譯器,可以在一個單獨的文件中定義所有的語法和代碼生成。Draak 是一個單獨的二進制文件,可以在任意平臺上只使用一個文件來編譯任何上下文無關的語言(類似 C, Pascal, Java)。
