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 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.

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
