Spring 2011 Prof. Hyesoon Kim• Game programming • Game architecture • Graphics programming • Computer architecture • Computer architecture case studies Game consoles • Emerging architecture • Graphics processor hardware • CUDA/OpenCL programming • Embedded processor programming (Nintendo DS programming)• CPU• GPU• If you want to develop – Xbox 720 Xbox 1440? – Playstation 4,5,6 ? • If you want to program efficiently using those hardware. – ARM Processors, Nintendo DS, PSP• Background – CS2200• http://www.cc.gatech.edu/~hyesoon/spr11/index.html• Nintendo DS programming (ARM) programming • More material on ARM, less material on computer architecture background • More Lab oriented. • Final Project• Leading the industry • Game processors are used for other applications– GPGPU:– Medical image processing – Scientific applications • Movie industries• Time constrain • Lots of Data • Heavy use of graphics• Both Integer/floating point operations are important • Floating point low precision• Stream applications • Embedded systems • Various I/O devices • No comparability issues (no reason to support legacy code)• All the platform is stable:• Platform optimizations• Every Friday • Lectures on CUDA Programming (first half of the semester)• Nintendo DS programming (the second half of the semester)• No TA– Help each other! – Use newsgroup to post and ask questions • Newsgroup activity is counted as class participation points. • [email protected]• Form a team (2 members) and choose a target game console/consoles • Game architectures/programming/available information • Examples – iPad, wii, PSP, iPhone, Android Phones, etc. – 3D game future?• Typically game programming • Using GPUs • Nintendo DS Programming • Using Tegra 2 Platform– Potentially provide full Tablet features – Dev development kit will be provided – No lab assignments• Still graphics is the major performance bottlenecks • Previous research: emphasis on graphics – 2D/3D graphics tests• Example: 3DMark Vantage – CPU and GPU tests – visual and game-play effects – CPU side: Physics Simulation and AI – Rendering tests (both CPU and GPU)• Several genres of video games– First Person Shooter• Fast-paced, graphically enhanced• Focus of this presentation– Role-Playing Games• Lower graphics and slower play– Board Games• Just plain boringEventPhysicsCollisionDetectionParticleAIRendering DisplayComputing• Current game design principles:– higher frame rates imply the better game quality• Recent study on frame rates [Claypool et al. MMCN 2006]– very high frame rates are not necessary, very low frame rates impact the game quality severelySnapshots of animation [Davis et al.
