Release Notes for X11R6.8.2 the X.Orgfoundation the Xfree86 Project, Inc
Release Notes for X11R6.8.2 The X.OrgFoundation The XFree86 Project, Inc. 9February 2005 Abstract These release notes contains information about features and their status in the X.Org Foundation X11R6.8.2 release. It is based on the XFree86 4.4RC2 RELNOTES docu- ment published by The XFree86™ Project, Inc. Thereare significant updates and dif- ferences in the X.Orgrelease as noted below. 1. Introduction to the X11R6.8.2 Release The release numbering is based on the original MIT X numbering system. X11refers to the ver- sion of the network protocol that the X Window system is based on: Version 11was first released in 1988 and has been stable for 15 years, with only upwardcompatible additions to the coreX protocol, a recordofstability envied in computing. Formal releases of X started with X version 9 from MIT;the first commercial X products werebased on X version 10. The MIT X Consortium and its successors, the X Consortium, the Open Group X Project Team, and the X.OrgGroup released versions X11R3 through X11R6.6, beforethe founding of the X.OrgFoundation. Therewill be futuremaintenance releases in the X11R6.8.x series. However,efforts arewell underway to split the X distribution into its modular components to allow for easier maintenance and independent updates. We expect a transitional period while both X11R6.8 releases arebeing fielded and the modular release completed and deployed while both will be available as different consumers of X technology have different constraints on deployment. Wehave not yet decided how the modular X releases will be numbered. We encourage you to submit bug fixes and enhancements to bugzilla.freedesktop.orgusing the xorgproduct, and discussions on this server take place on <[email protected]>. -

Comparative Study of Various Systems on Chips Embedded in Mobile Devices
Innovative Systems Design and Engineering www.iiste.org ISSN 2222-1727 (Paper) ISSN 2222-2871 (Online) Vol.4, No.7, 2013 - National Conference on Emerging Trends in Electrical, Instrumentation & Communication Engineering Comparative Study of Various Systems on Chips Embedded in Mobile Devices Deepti Bansal(Assistant Professor) BVCOE, New Delhi Tel N: +919711341624 Email: [email protected] ABSTRACT Systems-on-chips (SoCs) are the latest incarnation of very large scale integration (VLSI) technology. A single integrated circuit can contain over 100 million transistors. Harnessing all this computing power requires designers to move beyond logic design into computer architecture, meet real-time deadlines, ensure low-power operation, and so on. These opportunities and challenges make SoC design an important field of research. So in the paper we will try to focus on the various aspects of SOC and the applications offered by it. Also the different parameters to be checked for functional verification like integration and complexity are described in brief. We will focus mainly on the applications of system on chip in mobile devices and then we will compare various mobile vendors in terms of different parameters like cost, memory, features, weight, and battery life, audio and video applications. A brief discussion on the upcoming technologies in SoC used in smart phones as announced by Intel, Microsoft, Texas etc. is also taken up. Keywords: System on Chip, Core Frame Architecture, Arm Processors, Smartphone. 1. Introduction: What Is SoC? We first need to define system-on-chip (SoC). A SoC is a complex integrated circuit that implements most or all of the functions of a complete electronic system. -

Innovative AMD Handheld Technology – the Ultimate Visual Experience™ Anywhere –
MEDIA BACKGROUNDER Innovative AMD Handheld Technology – The Ultimate Visual Experience™ Anywhere – AMD Vision AMD has a vision of a new era of mobile entertainment, bringing all the capabilities of a camera, camcorder, music player and 3D gaming console to mobile phones, smart phones and tomorrow’s converged portable devices. This vision is quickly becoming reality. Mass adoption of image and video sharing sites like YouTube, as well as the growing popularity of camera phones and personalized media services, are several trends that demonstrate ever-increasing consumer demand for “always connected” multimedia. And consumers have demonstrated a willingness to pay for sophisticated devices and services that deliver immersive, media-rich experiences. This increasing appetite for mobile multimedia makes it more important than ever for device manufacturers to quickly deliver the latest multimedia features – without significantly increasing design and manufacturing costs. AMD in Mobile Multimedia With the acquisition of ATI Technologies in 2006, AMD expanded beyond its traditional realm of PC computing to become a powerhouse in multimedia processing technologies. Building on more than 20 years of graphics and multimedia expertise, AMD is a leading supplier of media processors to the handheld market with nearly 250 million AMD Imageon™ media processors shipped to date. Furthermore, AMD is a significant source of mobile intellectual property (IP), licensing graphics technology to semiconductor suppliers. AMD provides customers with a top-to-bottom family of cutting-edge audio, video, imaging, graphics and mobile TV products. The scalable AMD technology platforms are based on open industry standards, and are designed for maximum performance with low power consumption. -

Accelerating Augmented Reality Video Processing with Fpgas
Accelerating Augmented Reality Video Processing with FPGAs A Major Qualifying Project Submitted to the Faculty of Worcester Polytechnic Institute in partial fulfillment of the requirements for the Degree of Bachelor of Science 4/27/2016 Anthony Dresser, Lukas Hunker, Andrew Weiler Advisors: Professor James Duckworth, Professor Michael Ciaraldi This report represents work of WPI undergraduate students submitted to the faculty as evidence of a degree requirement. WPI routinely publishes these reports on its web site without editorial or peer review. For more information about the projects program at WPI, see http://www.wpi.edu/Academics/Projects. Abstract This project implemented a system for performing Augmented Reality on a Xilinx Zync FPGA. Augmented and virtual reality is a growing field currently dominated by desktop computer based solutions, and FPGAs offer unique advantages in latency, performance, bandwidth, and portability over more traditional solutions. The parallel nature of FPGAs also create a favorable platform for common types of video processing and machine vision algorithms. The project uses two OV7670 cameras mounted on the front of an Oculus Rift DK2. A video pipeline is designed around an Avnet ZedBoard, which has a Zynq 7020 SoC/FPGA. The system aimed to highlight moving objects in front of the user. Executive Summary Virtual and augmented reality are quickly growing fields, with many companies bringing unique hard- ware and software solutions to market each quarter. Presently, these solutions generally rely on a desktop computing platform to perform their video processing and video rendering. While it is easy to develop on these platforms due to their abundant performance, several issues arise that are generally discounted: cost, portability, power consumption, real time performance, and latency. -
