Montavista Linux Carrier Grade Edition
MontaVista Linux Carrier Grade Edition WHITE PAPER ABSTRACT: Communications networks are very different from other kinds of computing applications. Networks require both very high reliability and very high performance. Not only must they process large volumes of data at high speed, but they must do so while limiting their downtime to minutes per year. Network failures can have huge economic consequences and can even result in the loss of life. Additionally, in this post-9/11 world, failure also has a national security dimension. This technical whitepaper introduces MontaVista Linux Carrier Grade Edition— what it is, how it evolved, and how it provides a foundation for developing and deploying carrier-grade applications like those described above.

OM-Cube Project
OM-Cube project V. Hiribarren, N. Marchand, N. Talfer [email protected] - [email protected] - [email protected] Abstract. The OM-Cube project is composed of several components like a minimal operating system, a multi- media player, a LCD display and an infra-red controller. They should be chosen to fit the hardware of an em- bedded system. Several other similar projects can provide information on the software that can be chosen. This paper aims to examine the different available tools to build the OM-Multimedia machine. The main purpose is to explore different ways to build an embedded system that fits the hardware and fulfills the project. 1 A Minimal Operating System The operating system is the core of the embedded system, and therefore should be chosen with care. Because of its popu- larity, a Linux based system seems the best choice, but other open systems exist and should be considered. After having elected a system, all unnecessary components may be removed to get a minimal operating system. 1.1 A Linux Operating System Using a Linux kernel has several advantages. As it’s a popular kernel, many drivers and documentation are available. Linux is an open source kernel; therefore it enables anyone to modify its sources and to recompile it. Using Linux in an embedded system requires adapting the kernel to the hardware and to the system needs. A simple method for building a Linux embed- ded system is to create a partition on a development host and to mount it on a temporary mount point. This partition is filled as one goes along and then, the final distribution is put on the target host [Fich02] [LFS]. -

R.China Abstract The SSRF (Shanghai Synchrotron Radiation Facility) control system takes the Ethernet as backbone. All kinds PROTOTYPE OF SERIAL DEVICE of serial devices such as vacuum pumps are connected to CONTROLS AT SSRF Linux IOCs via a kind of Ethernet/serial box made by Moxa company. In the pre-research stage of SSRF, the old Nport5610 model of this Ethernet/serial box was only a simple Ethernet/serial protocol converter which was functioned In the pre-research stage of SSRF, Nport5610, which is by firmware. Aim to this, we have developed several a commercial Ethernet/serial box made by Moxa kinds of EPICS device drivers based on NetDev for our company [4] was chosen. It is composed of an arm9 CPU, serial devices. a small lcd screen, buttons, 8/16 serial ports and two Recently, Moxa company has upgraded the converter 10/100M Ethernet ports. Each Nport5610 has an IP by replacing old arm9 CPU with a more powerful Intel address on the Ethernet. Users are allowed to modify its Xscale CPU. It supports MontaVista Linux as its IP address and serial port parameters basically through embedded OS, also cross-compiler is provided to make telent/http or on the panel. Data flow from Ethernet is further development available. Since we have decided to forward to each serial devices in the way of "IP:PORT". use the new model of converter in our facility finally, we For example, to access serial device on port 4001, the manage to port EPICS IOC core on MontaVista Linux socket program will address "IP:4001". -

Of Computer and Information Science at Linköpings universitet Abstract The KreaTV Application Development Kit (ADK) product of Motorola en- ables application developers to create high level applications and browser plugins for the IPSTB system. As a result, customers will reduce develop- ment time, cost and supplier dependency. The main goal of this thesis was to port this platform to a standard Linux PC to make it easy to trace the bugs and debug the code. This work has been done by implementing a hardware abstraction layer(HAL)for Linux Operating System. HAL encapsulates the hardware dependent code and HAL APIs provide an abstraction of underlying architecture to the oper- ating system and to application software. So, the embedded platform can be emulated on a standard Linux PC by implementing a HAL for it. We have successfully built the basic building blocks of HAL with some performance degradation. -

Programmable Image-Based Light Capture for Previsualization
ii Abstract Previsualization is a class of techniques for creating approximate previews of a movie sequence in order to visualize a scene prior to shooting it on the set. Often these techniques are used to convey the artistic direction of the story in terms of cinematic elements, such as camera movement, angle, lighting, dialogue, and char- acter motion. Essentially, a movie director uses previsualization (previs) to convey movie visuals as he sees them in his ”minds-eye”. Traditional methods for previs include hand-drawn sketches, Storyboards, scaled models, and photographs, which are created by artists to convey how a scene or character might look or move. A recent trend has been to use 3D graphics applications such as video game engines to perform previs, which is called 3D previs. This type of previs is generally used prior to shooting a scene in order to choreograph camera or character movements. To visualize a scene while being recorded on-set, directors and cinematographers use a technique called On-set previs, which provides a real-time view with little to no processing. Other types of previs, such as Technical previs, emphasize accurately capturing scene properties but lack any interactive manipulation and are usually employed by visual effects crews and not for cinematographers or directors. This dissertation’s focus is on creating a new method for interactive visualization that will automatically capture the on-set lighting and provide interactive manipulation of cinematic elements to facilitate the movie maker’s artistic expression, validate cine- matic choices, and provide guidance to production crews. Our method will overcome the drawbacks of the all previous previs methods by combining photorealistic ren- dering with accurately captured scene details, which is interactively displayed on a mobile capture and rendering platform. -
The Growth of Android in Embedded Systems
THE GROWTH OF ANDROID IN EMBEDDED SYstEMS THE LINUX FOUNDATION TRAINING PUBLICATION Written by Benjamin Zores OVERVIEW Linux has continuously grown in the embedded systems market for over a decade, gaining market share from proprietary operating systems. The proliferation of embedded devices, the explosion of open source development, the inherent hardware support, the incredible networking capabilities and the royalty-free economic model have all helped propel use of the Linux kernel into one of the best choices for the design of new embedded systems. While the success of Linux in the embedded market can not be denied, its notoriety was once confined to mostly technical professionals. That changed in 2008 with Google’s release of the Android mobile phone operating system, based on the Linux kernel. Thus began the tremendous growth of Linux in the consumer world, with over one million Android devices being activated every day in 2012 and predictions of total Android devices shipped reaching one billion in 2013. THE GROWTH OF ANDROID 1 IN EMBEDDED SYstEMS of Android in THE GROWTH Embedded Systems In a recent The Android Operating System survey, 34% Android’s success was no accident and was the result of a long-term strategy and loads of investment from Google. The early development of the OS came from within Android Inc. of embedded in the early 2000’s; it was purchased by Google in 2005. The original system relied on a Java framework for its application layer and was not based on the Linux kernel. Only after engineers are several years of development at Google labs, and after an architecture revamping, the first Android-based smart-phone (the HTC G1) was released and based on the very first version considering of the Android software development kit (SDK). -
