First Mobile 3D Chip With a 128-Bit Engine.

SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 29, 1998--

First to Bring 128-bit 2D & 3D Engines to the Mobile Market

Low Power Hi-End Mobile Solution

Desktop Equivalent 3D

Single Chip DVD Solution

Silicon Motion(R), Inc. (SMI), a chipmaker addressing mobile computing and LCD display, today announced Lynx3D a new power managed, desktop equivalent display controller for notebook PCs.

The Lynx3D integrates the complete notebook computer graphics sub-system into a single chip utilizing a 192-bit architecture. Equal to desktop 3D performance, the Lynx3D, enables games/business 3D applications, provides all the components necessary for DVD playback, and embeds 2.5 Mbytes of DRAM while permitting 3 sets of independent outputs for LCD, CRT, and TV.

As the third product in Silicon Motion's Lynx line of display controllers, Lynx3D significantly highlights Silicon Motion's continuing effort to bring desktop equivalent capability to the mainstream and premium mobile markets.

"User's continues to drive growth and demand that mobile PC's match the performance and features of desktop PCs. The Lynx3D allows us to deliver a best-of-class graphics and video solution, and still offer a savings in power, which is vital in the mobile market," stated Wallace Kou, CEO for Silicon Motion.

High Performance Dual Memory Interface

The Lynx3D supports 2.5MB of embedded memory, and an external 64-bit SGRAM memory bus provides an additional 2MB or 4MB of memory. A unique two-memory controller architecture permits the embedded memory and external memory to run in parallel. This allows up to 192-bit memory architecture and up to 2.4GBytes of memory bandwidth.

For high performance 3D solutions, the 2.5MB of memory can be used as a dedicated texture cache, while front and back display buffers may be placed in external memory.

Full Featured 128-Bit 3D

The Lynx3D provides desktop level 3D performance within the power budget of a notebook system, and incorporates a 200MFlop IEEE Floating-Point Setup engine in addition to a full-featured 3D rendering engine. The setup engine is designed to balance with the triangle delivery capabilities of high-end notebook processors.

The rendering engine supports key features such as Mip Mapping, Bilinear/Trilinear Filtering, Alpha Blend, Anti-Aliasing, Specular Highlights, and Fog. Combined with the independent dual memory architecture, Lynx3D can achieve non-interrupted single cycle rendering.

DVD Playback

The Lynx3D provides the components necessary to display DVD content on any display type integrating Motion Compensation hardware for accelerating the decoding function.

Also integrated is a Video Processor that handles translations of different video formats, and alpha blends the sub-title onto the screen. Best of all, Lynx3D contains the output components needed to directly attach the LCD, CRT, or TV. Not only does Lynx3D contain all the DACs for the common CRT, but also a separate Macrovsion enabled Digital Encoder and 10-bit Y/C DAC for TV.

Fundamentals -- 2D GUI Performance

The Lynx3D did not forget the basics; the major function is still 2D GUI acceleration bringing the highest level performance for a notebook computer by being first with a 128-bit 2D GUI engine. Synchronized perfectly with the embedded DRAM, this engine can process 1.6 Gbytes of data in one second.

Pricing and Availability

The Lynx3D currently has samples available at a price of $49.50 each in quantities of one thousand. The device is available in a 272-pin or 316-pin BGA package.
