| CL-GD5480 Advance Product Bulletin FEATURES s 64-bit high-bandwidth synchronous DRAM interface -- 800 Mbytes/sec. peak memory bandwidth -- Supports modes up to 1600 x 1200, 64K colors at 60 Hz and 1280 x 1024, 16.8M colors at 75 Hz -- Provides significant additional memory bandwidth for BitBLT (bit boundary block transfer) and video window operations, even in high-resolution/color-depth graphics and video modes 64-Bit SGRAM GUI Accelerator OVERVIEW The CL-GD5480 is the latest member of the Cirrus Logic Alpine TM family and interfaces to a high-speed SGRAM (synchronous graphics RAM) frame buffer. This device delivers a high-performance combination of graphics, animation, betterthan-TV quality full-screen video, and software 3D acceleration in an integrated single-chip device. Packaged in a 208-pin PQFP and using the industry-standard VPort TM to interface directly to various video input devices, the CL-GD5480 offers a highly cost-effective and flexible VisualMediaTM solution. The V-Port, GPIO, and I2C bus interfaces provide a glueless connection to external devices to play back disk-based video files (including MPEG), and to provide TV-in-a-window, closed captioning, Intercast TM, and video conferencing. The CL-GD5480 has many features designed specifically to optimize Microsoft(R) DirectDraw TM performance. Hardware support for Microsoft Direct3DTM software also enables a costeffective 3D visual system. The CL-GD5480 is software-compatible with the Cirrus Logic Alpine family, featuring the industry's most stable software drivers, most extensive software QA process, and best language localization support. The VPMTM (video port manager) interface, an industry-standard driver API created by Cirrus Logic for Windows(R) 3.1x and Windows(R) 95, provides an easy path for V-Port peripheral application software development. s Microsoft(R) PC97-compliant -- -- -- -- Direct access to frame buffer independent of BitBLT Relocated VGA and BitBLT registers Subsystem, subsystem vendor ID Low-resolution modes for Direct3D TM s Video conferencing advantages -- Glueless digital camera interface with direct support of CCIR (ITR-U, International Radio Consultive Committee) 6:5:6 format -- Dual-hardware video window for local and remote viewing -- Optional PCI bus master conversion to YUV 4:2:0 for offloading CPU during local view transmission -- Remote and local view mirror image and vertical flip options -- Continuous XY filtered downscaling for video conference display size s Intel(R) Intercast TM support -- Luminance-only video capture mode for efficient VBI (vertical blanking interval) data processing -- Simultaneous capture and transfer of VBI data to system memory while TV picture is displayed in the video window -- PCI bus master write operation for fast transfer of VBI data to system memory without CPU intervention s MPEG playback assist -- Playback support for native MPEG format of planar YUV 4:2:0, freeing CPU of conversion burden s 3 x 8 palette LUT with independent RGB addressing for color adjustment (such as gamma correction) in 15-, 16-, and 24-bpp modes System Block Diagram OPTIONAL PERIPHERALS DVD MPEG DECODER GPIO V-Port TM TV TUNER TV DECODER I2C SGRAM 1, 2, 4 MBYTE 5 4 3 Block Diagram CL-GD5480 208-Pin PQFP 2 1 0 Video Conf Text Video Conf Text DIGITAL CAMERA PCI BUS CD-ROM HARD DRIVE MODEM POTS FOR VIDEO CONFERENCE October 1996 CL-GD5480 64-bit SGRAM GUI Accelerator ADVANTAGES Outstanding VisualMedia TM Acceleration s BitBLT command list in off-screen memory BENEFITS I Enhances graphics performance, especially for text.
