Features; 3D Accelerator; Video Accelerator/Video Capture - BCM Advanced Research IN440EX User Manual

(AGP). With AGP data the throughput between host and 3D RAGE PRO has greatly
increased. The result is even faster 2D and 3D performance and enhancements to motion
video support (e.g. MPEG-2 motion compensation).

FEATURES

3D Accelerator

• Complete 3D primitive support: points, lines, triangles, lists, strips and
Quadrilaterals
• Triangle Setup Engine with floating point to integer parameter conversion
4K on-chip Texture Cache
•
• Destination Alpha
• Gouraud shading
• Alpha blending and alpha interpolation
• 16-bit Z buffer
Fogging and fog interpolation
•
• Dithering support in 16 bpp for near 24 bpp quality
Perspectively correct mip-mapped texture mapping hardware, supporting:
•
• Palletized CI4 and CI8 texture expansion
• Texture filtering models including tri-linear mip mapping
• Texture lighting modes
• Ability to use YUV format textures
Alpha in texture map
•
• Texture maps up to 1024 x 1024
Non square texture maps
•
Software driver support for Direct 3D, QuickDraw 3D RAVE and OpenGL interfaces,
as well as others.

Video Accelerator/Video Capture

• Back end scaling
• Color interpolation during scaling for improved high resolution video quality
• Integrated 768 pixel wide dual video line buffers support filtered video scaling
4 tap horizontal and 2 tap vertical scalers for high-quality, full-screen video
•
playback with MPEG-2 (720x480) sources
YUV to ROB color space conversion with support for both packed and planar
•
YUV formats as follows:
• YUV422, YUV410 (YUV9), YUV420 (YUV12)
• RGB32, RGB16/15
• Built-in continuous brightness and gamma correction to correct 'dark' images
Chroma keying for effective overlay of video on graphics
•
• Overlay true color video regardless of the current graphics mode
New buffer and frame synchronization modes to reduce display tearing
