The CL-GD546X is the Laguna
patible, Rambus -based 2D/3D graphics accelera-
tors. The CL-GD5462, the first family member,
provides multi-window video and graphics accelera-
tion with greater-than-VRAM performance at lower-
than-VRAM cost. The follow-on product, the
CL-GD5464, offers 3D graphics capability in addi-
tion to maintaining the same high level of 2D perfor-
mance offered by the CL-GD5462.
The 64-bit graphics engine of the CL-GD546X fea-
tures standard GUI acceleration hardware as well as
advanced features such as stretch BLT and video
playback scaling. Color-key and chroma-key opera-
tions 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. T h e
CL-GD546X integrates a 24-bpp palette DAC, clock
generators, a full-feature VGA controller, and

... The CL-GD5465 also supports Intel’s AGP (acceler- ated graphics port) for higher bandwidth between the system memory and the graphics subsystem. Both the CL-GD5462 and CL-GD5464 are one- channel devices with bandwidth up to 600 Mbytes per second. While maintaining the same pin layout, future Laguna family members will use two Rambus channels to increase the bandwidth to 1 ...
