:OAKT), a provider of multimedia semiconductors and related software, today announced at World PC Expo A trade show for resellers, corporate managers and technical professionals from CMP Media LLC, a subsidiary of United Business Media. First held in New York in 1983 with 120 exhibitors and 9,600 attendees, the show grew from the personal computer's early years to 550 vendors and more than  (booth No. 7212) that its 3D graphics and audio chip solutions will become the main building blocks for forthcoming multimedia offerings from SANYO Technosound Co., Ltd.

A subsidiary of SANYO Electric Co., Ltd., SANYO Technosound will make its debut into the PC peripherals marketplace using Oak's WARP 5 3D graphics and Audia3D audio solutions.

The WARP 5 has received significant industry attention since its launch in July for the rich and unique feature set that it provides. By integrating several innovative rendering techniques, the WARP 5 delivers flight simulator-level 3D capabilities to mainstream PCs.

Oak's Audia3D was chosen by SANYO Technosound based upon its RAM-based DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive  and support of Microsoft's DirectSound, AC '97 compliance, and HRTF HRTF Head Related Transfer Function (3D Audio)  (Head-Related Transfer Function The head-related transfer function HRTF, also called the anatomical transfer function ATF, describes how a given sound wave input (parameterized as frequency and source location) is filtered by the diffraction and reflection properties of the head, pinna, ) 3D positional sound See 3D positional sound.  capability.

"For a successful debut into the PC peripherals market, it was imperative for us to partner with a company that offered expertise in both 3D graphics and PCI (1) (Payment Card Industry) See PCI DSS.

 audio," said Mr. Masahiko Kurosaki, president of SANYO Technosound. "Oak's WARP 5 and Audia3D solutions give SANYO Technosound the competitive edge we need to make our initial offerings compelling for the PC consumer."

In April of this year, SANYO's audio division was revamped and reorganized as SANYO Technosound Co., Ltd., a subsidiary of SANYO Electric Co., Ltd. With this new division, the company plans to expand its business interests into the multimedia PC peripherals market.

"SANYO's years of investment in consumer technologies combined with Oak's multimedia design expertise provides a win-win situation for both companies, and ultimately, the markets in which these solutions will be sold," said David Tsang, president of Oak Technology. "We are pleased to partner with this recognized leader in consumer electronics as they prepare to enter the PC marketplace."

Three-Dimensional Multimedia at its Best

3D technology is redefining expectations of what constitutes a rich audio and visual experience on the PC, especially in game applications. Oak has introduced products supporting both 3D graphics and 3D positional audio this year in an attempt to become a key enabler of 3D multimedia on the PC.

Oak's WARP 5 is a full-featured 3D graphics accelerator A display adapter that performs a specialized set of graphics functions to render an image on screen. Today, all display adapters provide basic rendering functions in hardware, but many have graphics processing units (GPUs) that are sophisticated computers.  that implements several advanced rendering techniques to deliver immersive 3D to the mainstream PC. The chip is highly integrated, combining a high-performance 2D GUI accelerator See graphics accelerator. , video, dual-clock generator and RAMDAC (Random Access Memory Digital to Analog Converter) The VGA controller chip that maintains the color palette and converts data from memory into analog signals for the monitor.

The WARP 5's innovative architecture minimizes memory bandwidth and capacity requirements, and reduces the subsystem cost, which is a key advantage for PC OEMs targeting the price-sensitive PC consumer.

Audia3D, Oak Technology's audio solution chosen by SANYO Technosound, brings the benefits of PCI, including higher bandwidth, reduced latency and more efficient resource usage to the PC sound card market. For end-users, this translates into a significant improvement in performance and enhanced audio realism.

Additionally, Oak's support for HRTF enables 3D positional multi-channel sound. The Audia3D also supports a variety of multimedia sound standards, including General MIDI compliant wavetable synthesis, multi-channel digital audio mixing, DirectInput, SoundBlaster Pro software emulation, Windows Sound System A sound card from Microsoft for Windows PCs. The card was not widely used, but certain characteristics of the card are built into Sound Blaster and other sound cards for compatibility with the Windows 3.1 drivers that were created at that time.  and the MPU-401 MIDI interface.
