This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder Described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent
and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3.

this a pack include source code for quartus 2.
It is an implementation of the LC2. The LC-2 computer is Described in Introduction to Computing Systems from Bits & Gates to C & Beyond by Yale Patt and Sanjay Patel, McGraw Hill, 2001. The LC2 model can be run as a simulation or downloaded to the UP3 in a larger model, TOP_LC2 that adds video output. Push buttons reset and single step the processor and a video output display of registers is generated. This state machine VHDL-based model of the LC-2 includes all source files. Currently compiled for a Cyclone EP1C6Q240 FPGA.
The Tremor Vorbis I stream and file decoder provides an embeddable, integer-only library [libvorbisidec] intended for decoding all current and future Vorbis I compliant streams. The Tremor libvorbisidec library exposes an API intended to be as similar as possible to the familiar vorbisfile library included with the open source Vorbis reference libraries distributed for free by Xiph.org.
Tremor can be used along with any ANSI compliant stdio implementation for file/stream access, or use custom stream i/o routines provided by the embedded environment. Both uses are Described in detail in this documentation.

Hidden_Markov_model_for_automatic_speech_recognition
This code implements in C++ a basic left-right hidden Markov model
and corresponding Baum-Welch (ML) training algorithm. It is meant as
an example of the HMM algorithms Described by L.Rabiner (1) and
others. Serious students are directed to the sources listed below for
a theoretical description of the algorithm. KF Lee (2) offers an
especially good tutorial of how to build a speech recognition system
using hidden Markov models.
FIST可堆疊文件系統，linux文件系統修改相關的開源軟件，使得對linux文件系統功能的改進很簡單了
The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be Described once. FiST s code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2％. These benefits are achieved, as well as portability, without changing existing operating systems or file system.
Traveling Salesman Problem (TSP) has been an interesting problem for a long
time in classical optimization techniques which are based on linear and nonlinear
programming. TSP can be Described as follows: Given a number of cities to visit
and their distances from all other cities know, an optimal travel route has to be
found so that each city is visited one and only once with the least possible distance
traveled. This is a simple problem with handful of cities but becomes complicated
as the number increases.
μC/OS-II Goals
Probably the most important goal of μC/OS-II was to make it backward compatible with μC/OS (at least from an
application’s standpoint). A μC/OS port might need to be modified to work with μC/OS-II but at least, the application
code should require only minor changes (if any). Also, because μC/OS-II is based on the same core as μC/OS, it is just
as reliable. I added conditional compilation to allow you to further reduce the amount of RAM (i.e. data space) needed
by μC/OS-II. This is especially useful when you have resource limited products. I also added the feature Described in
the previous section and cleaned up the code.
Where the book is concerned, I wanted to clarify some of the concepts Described in the first edition and provide
additional explanations about how μC/OS-II works. I had numerous requests about doing a chapter on how to port
μC/OS and thus, such a chapter has been included in this book for μC/OS-II.
DESIGN PATTERNS JAVA COMPANION
Design patterns began to be recognized more formally in the early
1990s by Helm (1990) and Erich Gamma (1992), who Described patterns
incorporated in the GUI application framework, ET++. The culmination of
these discussions and a number of technical meetings was the publication of
the parent book in this series, Design Patterns -- Elements of Reusable
Software, by Gamma, Helm, Johnson and Vlissides.(1995). This book,
commonly referred to as the Gang of Four or “GoF” book, has had a powerful
impact on those seeking to understand how to use design patterns and has
become an all-time best seller. We will refer to this groundbreaking book as
Design Patterns, throughout this book and The Design Patterns Smalltalk
Companion (Alpert, Brown and Woolf, 1998) as the Smalltalk Companion.
This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems. The first three editions of Programming the Finite Element Method established themselves as an authority in this area. This fully revised 4th edition includes completely rewritten programmes with a unique description and list of parallel versions of programmes in Fortran 90. The Fortran programmes and subroutines Described in the text will be made available on the Internet via anonymous ftp, further adding to the value of this title.
