Benefits of GPU compute in Mobile and Use cases



Akshay Agarwal has been in the semiconductor space with focus on software development, ecosystem and marketing roles. At ARM, Akshay is responsible for the Mali Ecosystem activities in the North America and works with a broad variety of partners including OS, Gaming, Browser and UI and partners


Imaging using ARM GPU

We present our work on using ARM T6xx GPU to implement a software image signal processor (ISP) that takes images captured by a camera sensor and reconstructs them for display and storage. We focus on non-standard imaging pipelines i.e. where input images are not in the standard Bayer pattern and thus where a typical hardware ISP would fail reconstruction. We will present video HDR pipeline using Aptina's interleaved HDR sensors.



Mikaël Bourges-Sévenier is Director of High-Performance Imaging at Aptina, a company making CMOS imaging sensors and image signal processors (ISP) for various markets such as mobile phones, automotive, and surveillance. He focuses on heterogenous imaging solutions using CPU, GPU, DSP, and ISP. Prior to Aptina, Mikaël was the Motorola’s Technical Lead for their Android Multimedia Applications. Before that he worked on multimedia applications using MPEG-4 for various companies such as France Telecom, iVAST, Sun, Dolby, Adobe. He has contributed to various MPEG specifications and is currently involved with Khronos Group on OpenCL, EGL, WebCL and is recently chairing the Camera Working Group.

    Can someone give me a link to more information on Micron's new RAM that includes search electronics? I forgot what it is called.

    Is the Mali frame compression lossy? Is so, how much does it affect image quality? Can/Has Mali be/been used for anything other than images?

      We don't use texture compression in our work as this would slow down frame rate.

      With 7,194,808,524 people now, Santa sure could use an upgrade from his 9 reindeer core.
