RS780E Features
•
2x/4x/8x/16x modes
•
Up to 128-tap texture filtering.
•
Adaptive algorithm with performance (bi-linear) and quality (tri-linear) options.
•
Improved quality mode due to improved subpixel precision, higher precision LOD computations, and
rotationally invariant LOD computations.
•
Advanced Texture Compression (3Dc+™ ):
•
High quality 4:1 compression for normal maps and luminance maps.
•
Works with any single-channel or two-channel data format.
•
HW support to overcome "Small batch" issues in CPU limited applications.
•
3D resources virtualized to a 32-bit addressing space, for support of large numbers of render targets and textures.
•
New vertex cache and vertex fetch design, to increase vertex throughput from previous generations.
•
Full support of 64-bit and 128-bit textures and surfaces, which can be 4x to 8x faster than previous generation of HW.
•
Up to 8K x 8K textures, including 128 bpp texture are supported.
•
New multi-level texture cache to give optimal performance, greater than 8x the previous designs.
•
High efficiency ring bus memory controller:
•
Programmable arbitration logic maximizes memory efficiency, software upgradeable.
•
Fully associative texture, color, and Z cache design.
•
New hierarchical Z and stencil buffers with early Z Test.
•
New lossless Z-buffer compression for both Z and stencil.
•
Fast Z-Buffer Clear.
•
Z cache optimized for real-time shadow rendering.
•
Z and color compression resources virtualized to a 32-bit addressing space, for support of multiple render targets
and textures simultaneously.
1.2.8
Motion Video Acceleration Features
•
Video scaling and fully programmable YCrCb to RGB color space conversion for full-speed video playback and fully
adjustable color controls.
•
Adaptive de-interlacing eliminates video artifacts caused by displaying interlaced video on non-interlaced displays,
and by analyzing image and using optimal de-interlacing function on a per-pixel basis.
•
Motion video acceleration for HD DVD/Blu-ray technology.
•
Dedicated UVD (Unified Video Decoder) hardware for H.264,VC-1, and MPEG-2 decode:
•
H.264 implementation is based on the ISO/IEC 14496-10 spec.
•
VC-1 implementation is based on the SMPTE 421M spec.
1.2.9
Multiple Display Features
