San Jose, Calif.--Oct. 22, 1997--Silicon Motion, Inc. (SMI), a chipmaker addressing mobile computing and entertainment appliance markets, has added the "LynxE" graphics accelerator IC to its family of "Lynx" multimedia controllers. The device is revolutionary in its capabilities to offer maximum performance with a 192-bit architecture while minimizing power consumption by utilizing dynamic power management. Portable PC OEMs also gain manufacturing benefits with its 2 megabytes of embedded memory and newly-added logic functions on a single chip.
Like its pin-compatible predecessor device, The LynxE features SMI'spatented VirtualRefresh architecture and advanced display managementtechnology. These unique characteristics allow simultaneous dual applications on two displays (combinations of LCDs, TVs, or CRTs) with different refresh rates, different resolutions, and different images. The newer LynxE device also enables independent full screen videos on separate displays (local/remote views), making it ideal forvideoconferencing. Desktop publishing applications and handheld devices also benefit by the new screen rotation feature. This new feature allows for on-the-fly switching from landscape to portrait display modes.
The LynxE's dual applications on dual display capabilities deliver end-user viewable and scaleable features to portable PC users who nowdon't have to wait for Windows98. Silicon Motion currently offers these features on operating systems such as Windows95, WindowsNT, as well as Windows98.
SMI estimates that less than half a watt is all that's needed for normal LCD-only operation mode under SMI's VirtualRefresh architecture. VirtualRefresh and dynamic power management results inlower power consumption, which means longer battery life for notebookusers.
Multimedia features of the LynxE include 2-D graphics, 3-D animation, MPEG2/DVD video playback, and video capture, among others. The Lynx family of controllers can display game action on TV and scores/controls on the LCD for games; can show full-screen motion video on TV; features an application user interface for Karaoke; and is TV-ready for presentations, games, motion video, Karaoke, and videoconferencing.
The LynxE incorporates a 135MHz Multimedia RAMDAC operating at 3.3 V;multiple clock synthesizers with extended PLL, concurrent video processor, 2-D/3-D drawing engine, video capture unit, memory controller, VGA core, PCI host interface unit, LCD backend controller, and power down control unit with dynamic power management.
To meet the high-performance, low-cost objectives of its LynxE chip,SMI employs 0.35-(m technology and advanced VLSI front-end and back-end design. The LynxE was implemented with modular logic design, while its hierarchical layout for physical design achieves optimal die size, timing control, and floor plan.
The LynxE (SM810) will be available in production quantities by Q1 1998 at a price of $42 each in quantities of 1,000. The device is available in a 256-pin BGA package.
