ART Vs. NDK Vs. GPU Acceleration: a Study of Performance of Image Processing Algorithms on Android
DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2017 ART vs. NDK vs. GPU acceleration: A study of performance of image processing algorithms on Android ANDREAS PÅLSSON KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF COMPUTER SCIENCE AND COMMUNICATION ART vs. NDK vs. GPU acceleration: A study of performance of image processing algorithms on Android ANDREAS PÅLSSON Master in Computer Science Date: June 26, 2017 Supervisor: Cyrille Artho Examiner: Johan Håstad Swedish title: ART, NDK eller GPU acceleration: En prestandastudie av bildbehandlingsalgoritmer på Android School of Computer Science and Communication iii Abstract The Android ecosystem contains three major platforms for execution suit- able for different purposes. Android applications are normally written in the Java programming language, but computationally intensive parts of An- droid applications can be sped up by choosing to use a native language or by utilising the parallel architecture found in graphics processing units (GPUs). The experiments conducted in this thesis measure the performance benefits by switching from Java to C++ or RenderScript, Google’s GPU acceleration framework. The experiments consist of often-done tasks in image processing. For some of these tasks, optimized libraries and implementations already exist. The performance of the implementations provided by third parties are compared to our own. Our results show that for advanced image processing on large images, the benefits are large enough to warrant C++ or RenderScript usage instead of Java in modern smartphones. However, if the image processing is conducted on very small images (e.g. thumbnails) or the image processing task contains few calculations, moving to a native language or RenderScript is not worth the added development time and static complexity. -

Apollo Twin USB Hardware Manual
Apollo Twin USB Hardware Manual Manual Version 210429 www.uaudio.com A Letter from Bill Putnam Jr. Thank you for deciding to make the Apollo Twin High-Resolution Interface part of your music making experience. We know that any new piece of gear requires an investment of time and money — and our goal is to make your investment pay off. The fact that we get to play a part in your creative process is what makes our efforts meaningful, and we thank you for this. In many ways, the Apollo family of audio interface products represent the best examples of what Universal Audio has stood for over its long history; from UA’s original founding in the 1950s by my father, through our current vision of delivering the best of both analog and digital audio technologies. Starting with its high-quality analog I/O, Apollo Twin’s superior sonic performance serves as its foundation. This is just the beginning however, as Apollo Twin is the only desktop audio interface that allows you to run UAD plug-ins in real time. Want to monitor yourself through a Neve® console channel strip while tracking bass through a classic Fairchild or LA-2A compressor? Or how about tracking vocals through a Studer® tape machine with some added Lexicon® reverb?* With our growing library of more than 90 UAD plug-ins, the choices are limitless. At UA, we are dedicated to the idea that this powerful technology should ultimately serve the creative process — not be a barrier. These are the very ideals my father embodied as he invented audio equipment to solve problems in the studio. -

Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Code ofoading is a popular technique for extending the natural capabilities of mobile devices by migrating processor-intensive tasks to resource-rich surrogates. Despite multiple platforms for ofoading being available in academia, these frameworks have yet to permeate the industry. One of the primary reasons for this is limited experimentation in practical settings and lack of reliability, scalability, and options for distribution. Tis paper introduces MobiCOP, a new code ofoading framework designed from the ground up with these requirements in mind. It features a novel design fully self-contained in a library and ofers compatibility with most stock Android devices available today. Compared to local task executions, MobiCOP ofers performance improvements of up to 17x and increased battery efciency of up to 25x, shows minimum performance degradation in environments with unstable networks, and features an autoscaling module that allows its server counterpart to scale to an arbitrary number of ofoading requests. -

This study examines the efficiency of certain software tasks in applications developed using three frameworks for the Android system: Android SDK, Qt and AppInventor. The results obtained using the Android SDK provided the benchmark for comparison with other frameworks. Three test applications were implemented. Each of them had the same functionality. Performance in the following aspects was tested: sorting a list of items using recursion by means of the Quicksort algorithm, access time to a location from a GPS sensor, duration time for reading the entire list of phone contacts, saving large and small files, reading large and small files, image conversion to greyscale, playback time of a music file, including the preparation time. The results of the Android SDK are good. Unexpectedly, it is not the fastest tool, but the time for performing most operations can be considered satisfactory. The Qt framework is overall about 34% faster than the Android SDK. The worst in terms of overall performance is the AppInventor: it is, on average, over 626 times slower than Android SDK. 1 Introduction The third part presents the results, which are then analysed. According to a recent study [1], the number of As already mentioned, currently the most popular smartphone users is forecasted to grow from 2.1 billion system for mobile devices is Android. -

Configuring the Information Environment of Microcomputers with the Microsoft Windows 10 Operating System
Configuring the Information Environment of Microcomputers with the Microsoft Windows 10 Operating System Felix Kasparinsky[0000-0002-1048-9212] MASTER-MULTIMEDIA Ltd, Entuziastov Shosse 98-3-274, Moscow 111531, Russia [email protected] Abstract. Since 2015, microcomputers have appeared in the information envi- ronment, which are a compact system unit with minimal functionality without peripherals. The article published the results of the analysis of the use of 6 dif- ferent microcomputers in various fields of activity. The purpose of the study is to determine the limiting factors affecting the efficiency of the targeted use of microcomputers. It has been established that for scientific and educational presentations, office and trading activities, it is cur-rently advisable to use fan- less microcomputers with a perforated case and an internal WiFi antenna, at least 4 GB of operational and 64 GB of permanent memory, and a microSD (TF) memory card slot, at least 128 GB, NTFS file system), Intel HD Graphics, USB3.0 and HDMI interfaces. Based on comparative experiments, methodolog- ical recommendations were created on optimizing the configuration of the hardware-software environment of microcomputers in stationary and mobile conditions. The problems of major updates to Windows 10, as well as the com- patibility of Microsoft Store software and third-party manufacturers, are ana- lyzed. It is recommended to specialize individual microcomputers for working with 32-bit applications; accounting and cryptographic programs; as well as conducting presentations with their video. Options for optimal configuration of the Start menu of the Windows 10 desktop are suggested. It is concluded that specialization in the hardware-software configuration of modern microcomput- ers allows you to increase the efficiency of using single de-vices and their paired systems in accordance with BYOD (Bring Your Own Device). -
