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.
Steganography is the art of communicating a message by embedding it into multimedia data. It is desired to maximize the
amount of hidden information (embedding rate) while preserving security against detection by unauthorized parties. An appropriate
information-theoretic model for steganography has been proposed by Cachin
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.
RS_latch using vhdl,
When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q.
Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.
Mastering the Requirements Process, Second Edition, sets out an industry-proven process for gathering and verifying requirements with an eye toward today s agile development environments. In this total update of the bestselling guide, the authors show how to discover precisely what the customer wants and needs while doing the minimum requirements work according to the project s level of agility.
This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. while the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.
What happens with your machine when you need to move away from the computer for 10 or more minutes? How secure is your data? Can someone sit on your chair while you are at a coworkers office and play with your data?
Maybe you need a computer locking tool that is small and easy to use yet powerful enough to make sure your machine is locked when you need to go out for a break.
A few years ago I became interested in first person shooter games and in particular how the world levels are created and rendered in real time. At the same time I found myself in between jobs and so I embarked on an effort to learn about 3D rendering with the goal of creating my own 3D rendering engine. Since I am a developer and not an artist I didn’t have the skills to create my own models, levels, and textures. So I decided to attempt to write a rendering engine that would render existing game levels. I mainly used information and articles I found on the web about Quake 2, Half Life, WAD and BSP files. In particular I found the Michael Abrash articles that he wrote for Dr. Dobbs magazine while working at Id to be very illuminating.
These are precompiled demonstration programs of the Onix toolkit. They do not include the Onix toolkit but are examples of very simple applications written with the toolkit. They are designed to show both how Onix works and also to show how easy it is to integrate the Onix toolkit into a project. while they show many of the features of the Onix toolkit, they don t show all of them. Please consult our documentation, available at our website, to see many of the features Onix gives you. We have included online the full documentation for the Onix toolkit.
If you are a C++ programmer who desires a fuller understanding of what is going on "under the hood," then Inside the C++ Object Model is for you!
Inside the C++ Object Model focuses on the underlying mechanisms that support object-oriented programming within C++: constructor semantics, temporary generation, support for encapsulation, inheritance, and "the virtuals"-virtual functions and virtual inheritance. This book shows how your understanding the underlying implementation models can help you code more efficiently and with greater confidence. Lippman dispells the misinformation and myths about the overhead and complexity associated with C++, while pointing out areas in which costs and trade offs, sometimes hidden, do exist. He then explains how the various implementation models arose, points out areas in which they are likely to evolve, and why they are what they are. He covers the semantic implications of the C++ object model and how that model affects your programs.
