Document Number: IMAGNATIONCOFS REV 1 cc ImaginationImagination T Technologiesechnologies presentspresents thethe Freescale i.MX31 Applications Processor Freescale i.MX31 Applications Processor The Freescale i.MX31 applications processor offers 2D/3D graphics acceleration through the inclusion of the PowerVR MBX Lite IP core designed by Imagination Technologies. The MBX Lite graphics processor is an IP core specifically developed to meet the growing multimedia needs of ultra-low power, cost-sensitive system-on-chip (SoC) applications such as mainstream mobile phones, PDAs and handheld gaming devices. When used with embedded microprocessor cores, MBX Lite enables the migration of complex 2D/3D graphics and video content to such platforms. MBX Lite has all the inherent benefits of the PowerVR architecture, including low memory bandwidth, advanced image quality and low power demands. 3D Features • Tile-based rendering - enables efficient on-chip processing of hidden-surface removal and pixel blending, and enables deferred texturing, eliminating all unnecessary accesses to off-chip memory. • Dynamic Scene ManagementTM - seamless scene complexity management to support arbitrarily complex scenes in limited memory footprints. • ITCTM - PowerVR Internal True Colour. Colour operations are performed on-chip at 32-bpp for superior colour precision and highest image quality. • PVR-TCTM - PowerVR texture compression for small memory footprints. All key 3D features are enabled, including: flat and Gouraud shading; perspective texturing; specular highlights; two-layer multitexturing; 32-bit Z support; full tile blend buffer; effective fill rates that increase with 3D scene complexity; per-vertex fog; 16-bit textures; 32-bit textures; YUV video textures; point, bilinear, trilinear and anisotropic filtering; full range of blend modes; alpha test; and full-scene anti-aliasing. PowerVR MBX Lite is fully compatible with all industry standard graphics APIs including OpenGL® ES 1.0, 1.1 and Direct3D Mobile. Start Developing Now! PowerVR Developer Relations offers various hardware-specific Software Development Kits (SDKs) and a general PC emulation SDK. These SDKs are freely available for download from www.pvrdev.com. These SDKs give access to the full specifications of PowerVR MBX-specific OpenGL® ES extensions, include free tools (PowerVR Texture compressor and compression library, 3D Studio Max exporter, VGP Vertex Program compiler including detailed performance information, etc.), and are supplied with an extensive tools library (fixed point math, matrix & vertex math, tangent space calculation, geometry import, etc.) and a large number of demonstration applications with full source code (dynamic reflections, different texture filter modes, projected shadow textures, polybump technology, spherical harmonics lighting with VGP, physics-based particle effects, cellshading, multiple differently coloured spotlights, morphing in combination with multi-texturing, matrix skinned characters with DOT3 per pixel lighting, etc.). www.powervr.com www.freescale.com [email protected] [email protected] A division of Imagination Technologies Ltd..

  • (GPU) Computing
    Graphics Processing Unit (GPU) computing This section describes the graphics processing unit (GPU) computing feature of OptiSystem. Note: The GPU computing feature is only configurable with OptiSystem Version 11 (or higher) What is GPU computing? GPU computing or GPGPU takes advantage of a computer’s grahics processing card to augment the speed of general purpose scientific and engineering computing tasks. Compute Unified Device Architecture (CUDA) implementation for OptiSystem NVIDIA revolutionized the GPGPU and accelerated computing when it introduced a new parallel computing architecture: Compute Unified Device Architecture (CUDA). CUDA is both a hardware and software architecture for issuing and managing computations within the GPU, thus allowing it to operate as a generic data-parallel computing device. CUDA allows the programmer to take advantage of the parallel computing power of an NVIDIA graphics card to perform general purpose computations. OptiSystem CUDA implementation The OptiSystem model for GPU computing involves using a central processing unit (CPU) and GPU together in a heterogeneous co-processing computing model. The sequential part of the application runs on the CPU and the computationally-intensive part is accelerated by the GPU. In the OptiSystem GPU programming model, the application has been modified to map the compute-intensive kernels to the GPU. The remainder of the application remains within the CPU. CUDA parallel computing architecture The NVIDIA CUDA parallel computing architecture is enabled on GeForce®, Quadro®, and Tesla™ products. Whereas GeForce and Quadro are designed for consumer graphics and professional visualization respectively, the Tesla product family is designed ground-up for parallel computing and offers exclusive computing 3 GRAPHICS PROCESSING UNIT (GPU) COMPUTING features, and is the recommended choice for the OptiSystem GPU.

My name is Shayne Hodge. This is July 29, 2013 at the afternoon in the Computer History Museum. We have with us today the founders of 3dfx, a graphics company from the 1990s of considerable influence. From left to right on the camera-- I'll let you guys introduce yourselves. Gary Tarolli: I'm Gary Tarolli. Scott Sellers: I'm Scott Sellers. Ross Smith: Ross Smith. Gordon Campbell: And Gordon Campbell. Hodge: And so why don't each of you take about a minute or two and describe your lives roughly up to the point where you need to say 3dfx to continue describing them. Tarolli: All right. Where do you want us to start? Hodge: Birth. Tarolli: Birth. Oh, born in New York, grew up in rural New York. Had a pretty uneventful childhood, but excelled at math and science. So I went to school for math at RPI [Rensselaer Polytechnic Institute] in Troy, New York. And there is where I met my first computer, a good old IBM mainframe that we were just talking about before [this taping], with punch cards. So I wrote my first computer program there and sort of fell in love with computer. So I became a computer scientist really. So I took all their computer science courses, went on to Caltech for VLSI engineering, which is where I met some people that influenced my career life afterwards.
