linux內核開發的經典書籍之一
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.

Introduction

The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs
new Cortex family. With high performance and power efficiency, it targets a wide
variety of mobile and consumer applications including mobile phones, set-top boxes,
gaming consoles and automotive navigation/entertainment systems. The Cortex-A8
processor spans a range of performance points depending on the implementation,
delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding
consumer applications and consuming less than 300mW for low-power mobile devices.
This translates into a large increase in processing capability while staying with the
power levels of previous generations of mobile devices. Consumer applications will
benefit from the reduced heat dissipation and resulting lower packaging and integration
costs.
Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network.
Toolbox contains also scripts for defining network structures (random networks, user defined networks) and traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for traffic matrix creation).
This article discusses some issues that a typical Windows C++ programmer will encounter when approaching
Symbian OS for the first time. Our experience in developing for three successive versions of Symbian OS has
given us considerable perspective on what can be difficult when working in this otherwise rich and stable
environment. While one reason for Symbian s success may be the desire of many mobile phone manufacturers not
to be tied to Microsoft, the other reason is that Symbian has put together a lightweight, elegant system that
succeeds in providing a very impressive range of functionality. Here are some pointers to help ease the transition to
successful Symbian OS application development.
The Kalman filter is an efficient recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements. It is used in a wide range of engineering applications from radar to computer vision, and is an important topic in control theory and control systems engineering. Together with the linear-quadratic regulator (LQR), the Kalman filter solves the linear-quadratic-Gaussian control problem (LQG). The Kalman filter, the linear-quadratic regulator and the linear-quadratic-Gaussian controller are solutions to what probably are the most fundamental problems in control theory.
For developers who design and program devices that use the USB interface. Introduce the USB
and help to get your devices and communicating as quickly and easily as possible.The USB is versatile enough for a wide range of peripheral devices. Standard peripherals that use USB include mice, keyboards, drives, printers,
and audio/video devices. USB is also suitable for data-acquisition units, control
systems, and other devices with specialized functions, including one-of-a-kind designs.
This document explains the pulse compression technique. Why it is required and how can it be used effectively. The pulse compression technique helps to increase the maximum range without sacrificing the range resolution and still the power requirement remains low.
