If you re like me, you re excited by what people do with template metaprogramming (TMP) but are frustrated at the lack of clear guidance and powerful tools. Well, this is the book we ve been waiting for. With help from the excellent Boost Metaprogramming Library, David and Aleksey take TMP from the laboratory to the workplace with readable prose and practical examples, showing that "compile-time STL" is as able as its runtime counterpart. Serving as a tutorial as well as a handbook for experts, this is the book on C++ template metaprogramming."Chuck Allison, Editor, The C++ Source

數(shù)字語音通信是當前信息產業(yè)中發(fā)展最快、普及面最廣的業(yè)務。語音信號壓縮編碼是數(shù)字語音信號處理的一個方面，它和通信領域聯(lián)系最為密切。在現(xiàn)有的語音編碼中，美國聯(lián)邦標準混合激勵線性預測（MELP—Mixed excited Linear Prediction）算法在2．4kb/s的碼率下取得了較好的語音質量，具有廣闊的應用前景。 FPGA作為一種快速、高效的硬件平臺在數(shù)字信號處理和通信領域具有著獨特的優(yōu)勢。現(xiàn)代大容量、高速度的FPGA一般都內嵌有可配置的高速RAM、PLL、LVDS、LVTTL以及硬件乘法累加器等DSP模塊。用FPGA來實現(xiàn)數(shù)字信號處理可以很好地解決并行性和速度問題，而且其靈活的可配置特性，使得FPGA構成的DSP系統(tǒng)非常易于修改、測試及硬件升級。 本論文闡述了一種基于FPGA的混合激勵線性預測聲碼器的研究與設計。首先介紹了語音編碼研究的發(fā)展狀況以及低速率語音編碼研究的意義，接著在對MELP算法進行深入分析的基礎上，提出了利用DSP Builder在Matlab中建模的思路及實現(xiàn)過程，最后本文把重點放在MELP聲碼器的編解碼器設計上，利用DSP Builder、QuartusⅡ分別設計了其中的濾波器、分幀加窗處理、線性預測分析等關鍵模塊。 在Simulink環(huán)境下運用SignalCompiler對編解碼系統(tǒng)進行功能仿真，為了便于仿真，系統(tǒng)中沒有設計的模塊在Simulink中用數(shù)學模型代替，仿真結果表明，合成語音信號與原始信號很好的擬合，系統(tǒng)編解碼后語音質量基本良好。

The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You ll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development.

Fun. We (your authors) wanted a word to describe our ultimate goal for this book, as well as a word we hope you (our reader) will use to describe it, and that’s the one we chose. There are others goals, of course, but in the end, when you’ve finished the book, we’re hoping you’ll have enjoyed the activities described in these pages. Many books use the Introduction to explain exactly what the book is about, what the reader will learn, what the reader needs (a skill or maybe an item or piece of software), and what the reader will be left with when that last page is completed. And this Introduction will do those things, but … hopefully it’ll make you excited to get started.
