Mobile phones are constantly decreasing in size, thereby complicating the acoustical functionality. Signal processing methods can be used to partially mitigate this problem. In this paper we suggest a method which uses multiple spectral subtraction functions and two microphones, introducing only a short signal delay.

The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the coding (compression) of natural video images. The new standard [1] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding: Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC). This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic Coding is assumed.

從結(jié)構(gòu)上來說，實(shí)時(shí)多任務(wù)操作系統(tǒng)包括兩部分，一部分為操作系統(tǒng)內(nèi)核(kernel)，即實(shí)時(shí)執(zhí)行程序(Real Time Executive:RTX)，另一部分是輸入輸出部分(I/O)(注意開發(fā)系統(tǒng)不屬于操作系統(tǒng)的范疇)；嵌入式系統(tǒng)對I/O的需求通常比較小(無文件系統(tǒng)需求)，因此很多實(shí)時(shí)多任務(wù)操作系統(tǒng)本質(zhì)上就是一個(gè)實(shí)時(shí)執(zhí)行程序，如AMX(Kadak)，VRTX(Microtec)，iRMX(Intel)等(這里的X即:eXecutive)，如果純粹從kernel的角度來考察目前流行的各種實(shí)時(shí)多任務(wù)操作系統(tǒng)的性能，它們的效率差別都不大。 在市面上可以得到一些RTX的源代碼(有用C實(shí)現(xiàn)的，有用匯編實(shí)現(xiàn)的，還有用PL/M語言實(shí)現(xiàn)的)，從internet上也可以蕩一些下來(我介紹一個(gè)站點(diǎn)www.eg3.com，堪稱世界電子工程師資源寶庫)，下面我要介紹的一個(gè)RTX版本(我命名為SRTX:short RTX)，可以說是RTX中的元老級產(chǎn)品了，來自某研究所，九十年代初他們到美國考察，從美國某公司購得。五年以前，SRTX在國內(nèi)有售，許多搞工控的研究所利用SRTX開發(fā)了一些大型或小型的產(chǎn)品,這里介紹的SRTX我作了一些簡化和改動.

This book shows how to design and implement C++ software that is more effective: more likely to behave correctly more robust in the face of exceptions more efficient more portable makes better use of language features adapts to change more gracefully works better in a mixed-language environment is easier to use correctly is harder to use incorrectly. In short, software that s just better.
