W9971CF
DESCRIPTION
Winbond s W9971CF is a highly-integrated VLSI providing high performance graphics acceleration and TV-quality full screen motion video acceleration for IBM PCs or patibles. The W9971CF integrates an NTSC/PAL TV encoder with S-Video or posite video for flicker-free and glueless TV output. An on-chip RAMDAC and a dual programmable clock synthesizer with a 170 MHz pixel data rate are also integrated into the chip to simplify system design and reduce cost. The W9971CF is a high-performance graphics accelerator specially designed for Microsoft Windows, Mac OS, IBM OS/2, and DOS-based applications. In addition to 100% IBM VGA registerlevel patibility, the W9971CF incorporates a 64-bit graphics engine (GE) to accelerate drawing functions such as bit block transfer (Bit BLT), line drawing, clipping, and hardware cursor manipulation. The W9971CF s integrated video accelerator (VA) features high-quality video filtering, bilinear interpolating scaling along both the X and Y axes,...
