Multiprocessing in Mobile Platforms: the Marketing and the Reality
Multiprocessing in Mobile Platforms: the Marketing and the Reality Marco Cornero, Andreas Anyuru ST-Ericsson Introduction During the last few years the mobile platforms industry has aggressively introduced multiprocessing in response to the ever increasing performance demanded by the market. Given the highly competitive nature of the mobile industry, multiprocessing has been adopted as a marketing tool. This highly visible, differentiating feature is used to pass the oversimplified message that more processors mean better platforms and performance. The reality is much more complex, because several interdependent factors are at play in determining the efficiency of multiprocessing platforms (such as the effective impact on software performance, chip frequency, area and power consumption) with the number of processors impacting only partially the overall balance, and with contrasting effects linked to the underlying silicon technologies. In this article we illustrate and compare the main technological options available in multiprocessing for mobile platforms, highlighting the synergies between multiprocessing and the disruptive FD-SOI silicon technology used in the upcoming ST-Ericsson products. We will show that compared to personal computers (PCs), the performance of single-processors in mobile platforms is still growing and how, from a software performance perspective, it is more profitable today to focus on faster dual-core rather than slower quad-core processors. We will also demonstrate how FD-SOI benefits dual-core processors even more by providing higher frequency for the same power consumption, together with a wider range of energy efficient operating modes. All of this results in a simpler, cheaper and more effective solution than competing homogeneous and heterogeneous quad-processors. -

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. -
