•
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.
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.
•
H.264 implementation is based on the ISO/IEC 14496-10 spec.
•
VC-1 implementation is based on the SMPTE 421M spec.
•
For the RS880MC: MPEG-2 decode acceleration for SD
contents:
•
Hardware motion compensation.
•
Hardware Inverse Discrete Cosine Transform.
•
Multiple Display Features
General
•
Resolution, refresh rates, and display data can be completely
independent for the two display paths.
•
¡E Each display controller supports true 30 bits per pixel
throughout the display pipe.
•
¡E Each display path supports VGA and accelerated modes,
video overlay, hardware cursor, hardware icon, and palette
gamma correction.
•
Supports both interlaced and non-interlaced displays.
•
Full ratiometric expansion ability is supported for source desktop
modes up to 1920 pixels/line.
•
Maximum DAC frequency of 400 MHz.
•
Supports 8, 16, 32, and 64-bpp depths for the main graphics
layer:
•
For 32-bpp depth, supports xRGB 8:8:8:8, xRGB 2:10:10:10,
sCrYCb 8:8:8:8, and xCrYCb 2:10:10:10 data formats.
•
For 64-bpp depth, supports xRGB 16:16:16:16 data format.
•
Independent gamma, color conversion and correction controls
for main graphics layer.
•
Support for DDC1 and DDC2B+ for plug and play monitors.
•
8-bit alpha blending of graphics and video overlay.
