  1. GPU – Graphic Processing Unit Hao Yu Computer Architecture and Design

  2. Content • Instruction • History • Different types of GPUs • Recent Development

  3. Instruction • GPU (graphics processing unit ) is a RISC specialized processor that offloads 3D graphics rendering from microprocessor.

  4. Instruction • GPUs are mainly used in embedded systems, mobile phones, personal computers, workstations and game consoles.

  5. History • 1970s: ANTIC and CTIA chips provided for hardware control of mixed graphics and text modes, sprite positioning and display, and other operations based on Atari 8-bit computers. • 1980s: IBM Professional Graphics Controller was one of the very first 2D/3D graphics accelerators available for the IBM PC, released in 1984. But it was expensive, slow and lack of compatibility.

  6. History • 1990s: S3 Graphics introduced the first single-chip 2D accelerator (S3 86C911); in mid-1990s, PlayStation and Nintendo 64 developed hardware-accelerated 3D graphics for the requirement of game market. • 2000s: NVIDIA was first to produce a chip capable of programmable shading, GeForce 3 (NV20); Oct. 2002, ATI Radeon 9700 (R300), was introduced as the world’s first Direct3D 9.0 accelerator.

  8. Different types of GPUs • Dedicated Graphics Card • Integrated Graphics • Hybrid Graphics

  9. Recent Development – Larrabee

  10. Recent Development – Larrabee • Differences from other GPUs 1. Larrabee will use the x86 instruction set with Larrabee-specific extensions; 2. Larrabee will feature cache coherency across all its cores; 3. Larrabee will include little specialized graphics hardware, by using a tile-based rendering way. • More flexible
