I'll take a daughtercard. Siemens reveals scan converter chip with embedded DRAM for PC-TV.................. techweb.cmp.com Siemens embeds DRAM on scan-converter IC By David Lammers YOKOHAMA, Japan -- Siemens Semiconductor came to an international forum on multifunction TVs here with something that none of the Asian memory powerhouses has yet to accomplish: a scan-rate converter IC with embedded DRAM. Higher performance scan-rate converters are required as more televisions display Web pages and computer functions. Herwig Benning, a marketing manager, said that the driving force behind the company's Scarabaeus device was the need to merge TV and PC applications on a television. What Siemens calls "megavision" progressive-scan technology can be applied to display graphic, text and still pictures on a television, turning the TV into a PC monitor. Also, large-area flickering is reduced in TV applications with greater than 60 Hz operation. Scarabaeus is more than a chip. It incorporates extensive algorithmic work, done at Siemens and cooperating research institutes. These algorithms differ from the traditional line-doubling progressive-scan mode algorithms used thus far, he said. Though he declined to provide details, Benning said 0.35-micron Scarabaeus includes 5.2 Mbits of embedded DRAM, with 192 kbits of that reserved for the line memory function and the remaining 5 Mbits as picture memories. The device performs 100/120-Hz interlaced scan conversion, or 50/60-Hz progressive-scan conversion. Motion-adaptive spatial and temporal noise reduction, and automatic measurement of the noise level, are performed on-chip. When combined with a picture-in-picture device, Scarabaeus supports up to nine multiple picture displays. The Siemens presentation was part of a one-day forum on "Next Generation Multi-Function TV and Multimedia" sponsored by the Japan chapter of the Semiconductor Industry Association; and by the Semiconductor User's Committee of the Electronic Industries Association of Japan; by the European Electronic Components Association; by the Korean Semiconductor Industry Association; and by Insec, Japan's semiconductor promotion organization. About 285 Japanese engineers came to listen to the presentations of 11 U.S. and European companies. The television forum, and a similar seminar on automotive electronics held earlier this fall, marked the first time that European companies participated in the import promotion forums, said Roger Mathus, Japan representative of the SIA.
