The CL-GD546X is the Laguna TM family of pin-compatible, Rambus-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 b e c o m b i n e d i n a n e f fi c i e n t m a n n e r.
