(cont.)

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

V-Port
