Trident CyberBLADE XP Family Achieves Best Desktop 3D for AGP 4X Notebook

Leapfrog quality and performance for mainstream desktop

Santa Clara, California. April 19, 2000:

Trident Microsystems, Inc. (NASDAQ: TRID) today introduced the BLADE XP™ family of 256-bit graphics processors for next-generation, mainstream 3D/2D PC desktop graphics and digital media applications. The new mainstream desktop product family consists of the 200MHz BLADE XP tailored for maximum performance and the 150MHz BLADE XP optimized for lowest system cost.

"The 150 MHz BLADE XP graphics processor has been meticulously optimized by our design team to achieve the best balance possible between 3D graphics performance, advanced feature set and excellent image quality while minimizing total system cost for mainstream desktop applications," said Mr. Le T. Nguyen, senior director of desktop graphics marketing at Trident Microsystems. "The 200 MHz BLADE XP represents a major breakthrough in clock rate for mainstream 3D graphics processors while only consuming 2.8 watts, a mere fraction of competitive devices at a comparable performance level."

The BLADE XP family brings forth seven major technical advances in video/graphics capability to mainstream desktop PCs: DirectX 7.0 Cubic Mapping, 256-bit pixel processing, dual memory bus architecture, AGP-4X bus interface, state-of-the-art video de-interlacing, high-resolution flat panel and only 2.8watt power consumption at a blazing 200MHz clock rate.

The Cubic Mapping feature in the latest DirectX 7.0 graphics standard from Microsoft was based on Trident's BLADE XP original work, which enables highly accurate real-time modeling of reflection and refraction of multiple light sources, and marks a new era in photo-realistic 3D rendering in mainstream desktop PCs.

The 256-bit Dual Pixel pipeline hardware in BLADE XP provides single-pass processing of advanced DirectX 7.0 features such as multi-texture rendering, per-pixel Phong-quality lighting, bump mapping, texture compression, Z and W depth cueing, etc.. The BLADE XP's innovative dual memory bus architecture solves the classical problem of inefficient memory bus utilization by minimizing SGRAM/SDRAM page misses due to interleaved color and Z memory accesses.

With a peak data transfer rate of over 1 GB/sec, the AGP-4X host interface in BLADE XP doubles the communication bandwidth of the earlier generation AGP-2X bus and allows much faster access of texture memory providing most of the richness in 3D graphics applications.

The BLADE XP's trail-blazing video de-interlacing function marks the first of its kind for digital media applications, and represents the state-of-the-art in displaying interlaced TV video sources on VGA monitors at a level of quality not found in any other high-end desktop PCs. Besides supporting the CRT with a 350MHz RAMDAC, BLADE XP also supports a simultaneous flat panel which interfaces to a 12-bit, 170MHz data bus with a standard external TMDS driver enabling up to the UXGA resolution (1600x1280), another first for mainstream desktop PCs. Additionally, the ultra low power consumption of 2.1 watts at 150 MHz (or 2.8 watts at 200 MHz) is the result of combining advanced power management technology with a cost-effective 0.18um CMOS process.

Trident's industry-pioneering DVD solution previously integrated the playback software with on-chip motion compensation and is now further improved with additional on-chip Inverse Discrete Cosine Transform (IDCT) hardware, which reduces host CPU processing requirement to below 15%, and would enable a real-time playback of the emerging high-resolution HDTV video content.

The BLADE XP can support up to 32MB of local frame buffer using high-performance 512Kx32, 1Mx32 or 2Mx32 SGRAM memory. Alternatively, low-cost SDRAM memory is also supported in multiple configurations, including 1Mx16, 4Mx16, 1Mx32 and 2Mx32.

The BLADE XP comes in a 457-pin Ball Grid Array (BGA) package, and is sampling now, with mass production in Q3 2000. In 10,000 unit quantities, the 150 MHz BLADE XP and 200 MHz BLADE XP are priced at $27 and $32 each, respectively.
