Acceleration Features; Motion Video Acceleration Features - AMD RS690M Technical Reference Manual

•
Support for GDI extensions in Windows XP and Windows Vista: Alpha BLT, Transparent BLT, Gradient Fill.
•
Hardware cursor (up to 64x64x32bpp), with alpha channel for direct support of Windows XP and Windows Vista
alpha cursor.
1.5.7 3D Acceleration Features
•
Multi-texturing via one texture blending unit per pixel pipes, allowing up to 512 texel reads per pixel in a single pass.
•
3D texture support, including projective 3D textures.
•
Comprehensive support for bump mapping: emboss, dot-product, and environment bump maps.
•
Improved precision in anisotropic filtering and bilinear filtering.
•
Complete 3D primitive support: points, lines, triangles, lists, strips and quadrilaterals and BLTs with Z compare.
•
Improved texture compositing.
•
Hidden surface removal using 16, 24, or 32-bit Z-buffering (maximum Z-buffer depth is 24 bits when stencil buffer
enabled) and Early Z hardware.
•
8-bit stencil buffer.
•
Bilinear and trilinear texture filtering.
•
Full support of Direct3D
•
Dithering support in 16bpp for near 24bpp quality in less memory.
•
Extensive 3D mode support.
•
Anti-aliasing using multi-sampling algorithm with support for 2, 4, and 6 samples.
•
Optimized for full performance in true color triple buffered 32bpp acceleration modes.
•
New generation rendering engine provides top 3D performance.
•
Support for OpenGL format for Indirect Vertices in Vertex Walker.
•
Full DirectX 9.0 support (Vertex Shader version 2.0 and Pixel Shader version 2.0):
•
Full precision floating point pixel pipeline.
•
Support for up to 4 MRTs (Multiple-Render-Targets).
•
Support for writing all texture formats from render pipe in floating points (including cube mapes and 3D
textures).
•
Support for up to 512bpp formats (4 color case).
•
Advanced setup engine, capable of processing 1 polygon (lit and textured) per cycle.
1.5.8

Motion Video Acceleration Features

•
Enhanced MPEG-2 hardware decode acceleration (SD contents only), including support for:
•
Integrated general purpose iDCT engine for MPEG2 and DV decode acceleration.
•
Integrated MPEG motion compensation engine for decode acceleration.
•
Parallel operation of the iDCT and MC and high processing rates with minimal software overhead.
•
Supports Microsoft DirectX Video Acceleration (DirectX VA) 2.0 (for SD contents only).
•
Provides dramatically reduced CPU utilization without incurring the cost of a full MPEG-2 decoder.
•
MPEG-4 simple profile support.
•
Supports top quality DVD with low CPU usage.
•
Hardware-based adaptive de-interlacing filter and scaler provide high quality full-screen and full-speed video
playback. Minimizes the aliasing artifacts along edges usually caused by a conventional deinterlacer/scaler.
