Description

The CL-GD546X is the Laguna^TM family of pin-compatible, Rambus â-based 2D/3D graphics accelerators. The CL-GD5462, the first family member, provides multi-window video and graphics acceleration with greater-than-VRAM performance at lowerthan- VRAM cost. The follow-on product, the CL-GD5464, offers 3D graphics capability in addition to maintaining the same high level of 2D performance offered by the CL-GD5462.

The 64-bit graphics engine of the CL-GD546X features standard GUI acceleration hardware as well as advanced features such as stretch BLT and video playback scaling. Color-key and chroma-key operations are supported to enable graphics and video to be combined in an efficient manner. The CL-GD546X integrates a 24-bpp palette DAC, clock generators, a full-feature VGA controller, and V-Port^TM bus for easy expandability.
