汇编器在微处理器的验证和应用中举足轻重，如何设计通用的汇编器一直是研究的热点之一。本文提出了一种开放式的汇编器系统设计思想，在汇编语言与机器语言间插入中间代码CMDL（code mapping description language）语言，打破汇编语言与机器语言的直接映射关系，由此建立起一套描述汇编语言与机器语言的开放式映射体系。基于此开放式映射体系开发了一套汇编器系统，具有较高层次上的通用性和可移植性。【关键词】指令集，CMDL，汇编器，开放式 Design of Retargetable Assembler System Liu Ling Feng Wen Nan Wang Ying Chun Jiang An Ping Ji Li Jiu IME of Peking University, 100871【摘要】An assembler plays a very important role in the field of microprocessor verifications and applications, thus how to build a retargetable assembler system has been a hotspot in this field for long time. This paper presents a new method about the retargetable assembler system design.It provides a kind of language CMDL, code mapping description language. During the process of assembling, assembler languages are firstly translated to CMDL, and then mapped to the machine codes. In an other word, CMDL is inserted between assembler languages and machine codes during the TranslATion procedure. As a medium code, CMDL has a lot of features, such as high extraction, strong descript capabilities. It can describe almost all attributes of assembler languages. By breaking the direct mapping relationship between assembler languages and machine codes, the complexities of machine codes are hided to the users, therefore, the new retargetable assembler system has higher retargetable level by converting the mapping from assembler languages and machine codes to assembler languages and CMDL, and implementationof it becomes easier. Based on the new mapping system structure, a retargetable assemblersystem is developed. It proved the whole system has good retargetability and implantability.【关键词】instruction set, symbol table, assembler, lexical analysis, retargetability

ADOM+设计篇意在测试com+的事务处理能否正确执行。 将组件安装后，在组件服务中该com+组件的属性设置中将“激活”页的“启用对象池”选项选中，执行客户端程序调用上面这个方法，发现com+的事务机制不能正确执行，数据会写入数据库中。如果不选中“启用对象池”，则一切正常，数据并不会写到数据库中。 说明：TranslATion DataModule的设置，事务属性：requires a transaction,允许object pooling，pooled设为true,无论将AutoComplete设为True或False都会出现上述情况。 该问题最先由ytwxw (wxw) 提出，至今尚未有结论，我也发现类似问题。我俩探讨后无法解决，特在此再开一贴。请各路com+高手帮忙解答!

ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. Ordinary usage: [R, T] = icp(model,data) INPUT: model - matrix with model points, data - matrix with data points, OUTPUT: R - rotation matrix and T - TranslATion vector accordingly so newdata = R*data + T . newdata are transformed data points to fit model see help icp for more information

JaNet: Java Neural Network Toolkit resume: A well documented toolkit for designing and training, and a java library for inclusion in third party programs. description: jaNet package is a java neural network toolkit, which you can use to design, test, train and optimize an ideal Neural Network for your private application. You can then include your saved network in your program using the jaNet.backprop package. The consequent documentation is only in french for the moment, but an english TranslATion is planned. The java source code is released under GPL, and can be compiled with JDK, Symantec Cafe or MS Visual J

This book code procedure according to the chapter arrangement, the 1st chapter of example under "1" the table of contents, the 2nd chapter of example under "2" the table of contents, to the order analogizes. Under corresponding table of contents including Java source code document and by it correspondence TranslATion class document. The reader may use software and so on the text editor opens the Java source code document, examines this book the detailed code. 13th chapter the code defers to the project project laying aside. May directly use NetBeans to open the project document to carry on the code examination.

DSR-UU is a DSR implementation that runs in Linux and in the ns-2 network simulator. DSR-UU implements most of the basic DSR features specified in the DSR draft (version 10). One big exception is flow extensions. DSR-UU does NOT use ARP, so do not be surprised if you do not see ARP traffic. DSR-UU instead uses its own neighbor table that sets up the MAC-to-IP TranslATion during route discovery.

This book has been written to support a practically oriented course in programming language TranslATion for senior undergraduates in Computer Science. More specifically, it is aimed at students who are probably quite competent in the art of imperative programming (for example, in C++, Pascal, or Modula-2), but whose mathematics may be a little weak students who require only a solid introduction to the subject, so as to provide them with insight into areas of language design and implementation, rather than a deluge of theory which they will probably never use again students who will enjoy fairly extensive case studies of translators for the sorts of languages with which they are most familiar students who need to be made aware of compiler writing tools, and to come to appreciate and know how to use them. It will hopefully also appeal to a certain class of hobbyist who wishes to know more about how translators work.
