INFORMATION RELEASE TSENG ET400/W32 CHIP Date: Sep 4, 1992 Tseng Labs Inc. (PA. USA) has started sampling it's ET4000/W32 Multi- processing, Multi-tasking SVGA chips. At the Microsoft Window Hardware conference Sept 1 '92, the ET4000/W32 showed a Winmark of 28 million pixels/sec - over 60% faster than any other DRAM or VRAM Windows accelerator cards shown at the conference. The figure will be further improved with newer software drivers. Windows' performance is not TSENG ET4000/W32's only strength, it offers other important advantages : * Compatibility The ET4000/W32 is hardware and software compatible with approximately 5,000,000 ET4000 installations. This compatibility protects users' old investments on software/ hardware and offers a very powerful growth path. * 16-bit/32-bit bus with Video Cache ET4000 has been widely recognized for its excellent Local Bus performance due to its video cache technology. The ET4000/W32 has a 2nd generation video cache technology which offers better performance and an architecture for future products such as the ET4000/W64. * Windows acceleration ET4000 is designed for improvement of Windows performance and multimedia applications instead of cloning IBM 8514/A or XGA. It out-performs and out functions 8514/A and XGA. * Imaging Port and hardware Window The ET4000/W32 offers an Imaging Port to accept imaging data and can display the image on a hardware window. Hardware Zoom and Video functions will be available on early 1993 with a small ASIC chip complimentary to ET4000/W32. * Simultaneous multi-processing The ET4000/W32's Windows accelerator, CRTC and Imaging Port can operate simultaneously. Most other Windows accelerators can only do one task at the time (Example : When CPU writes to display memory, Windows accelerator has to stop or vice versa). It's multi-processing capability will be able to take advantage of multi-thread capability of new operating systems such as Windows NT. * High color and True color ET4000/W32 supports 800x600 in 24-bit true color, and 1280x1024 in 16-bit color. * Low-cost DRAM The ET4000/W32 requires only 80ns ot 70ns DRAM to provide high performance and multi-processing capability. Tseng is now delivering 1st-iteration chips which contains some minor bugs. "We fully acknowledge and document these bugs. We know the errors and their solutions. The 2nd iteration will be available to customers at early Oct. 92 and will correct all those bugs. For such a powerful and sophisticated chip the achievement of 1st iteration chips of ET4000/W32 proves Tseng's technological excellence" said Jack Huang, President of TsengLabs International Co., Ltd. at Taipei. With about 5 million ET4000 chips installations and the new ET4000/W32 chip, Tseng positions to continue to set standard and paces of PC graphics display technology.
