Rosun Launches Industry's Most Versatile Line of MP3 Chips
Single, Programmable 2.5V DSP Chip Replaces Multiple Chip Solutions and can be Customized to Fit a Wide Variety of Internet Appliances
FREMONT, Calif., Aug. 15 /PRNewswire/ -- Rosun(TM) Technologies today announced the debut of its new family of MP3 decoder chips, created for next-generation Internet appliances and designed to be the most versatile MP3 chips ever made. Rosun's MP3 decoders are based on a single DSP chip design that can be programmed to support a wide-variety of applications without recasting a new chip-enabling it to replace competing multiple chip solutions with a single chip.
The versatility of the Rosun chips enables them to be customized to support specific applications and devices. For instance, if a new audio format were to emerge as a standard for downloadable audio, Rosun would simply reprogram the firmware of its MP3 decoder chips to fully support the new standard -- competing companies would need to create a new chip to offer the same support. Similarly, once a consumer purchases a device powered by Rosun, it can be upgraded with additional functionality through the Web, eliminating the need to buy new devices to support new technologies. Rosun's MP3 decoder chips also boast a superior architecture allowing it to consume less power, an important attribute for portable and Internet devices. Rosun's chips are also smaller than competing chips, further making them a more cost-effective alternative.
``High integration, high performance and low power are the hallmarks of Rosun's chips,'' said Bruce Sun, president and co-founder of Rosun. ``Our new line of MP3 decoder chips meet those standards and can be customized quickly and easily to give Internet appliances the ability to play a variety of audio formats in 3D sound.''
Why MP3?
MP3 is an audio compression format that enables CD quality sound at 1/10 the file size, making it easily distributed across the Web. Currently, MP3 is the second most common search term on the Internet and has further been popularized by such file-sharing applications as Napster, Gnutella, Freenet and others. A new generation of electronics -- or Internet appliances -- are being created that can access the Internet and take advantage of the popularity of MP3s. One category of these devices is appliances that can play high quality CD, MP3 and Internet music. Most of these Internet appliances use 3 to 8 chips to enable the multiple audio formats and applications. The Rosun single chip solution enables the use of multiple media formats for various MP3 devices and applications in this dynamic and growing market.
Rosun's proprietary MP3 decoder chips are designed to play MP3 CDs and Internet audio in 3D sound. The functionality of its design enables it to be used in wide variety of ways -- Internet appliances, next-generation electronics, toys, portable MP3 players, CD-R and CD-R/W. The entire family of chips is designed to interface with both the Intel 8051 and Motorola 68H11, the most popular micro controllers in the industry, meaning Rosun's MP3 chips are compatible with most current computing devices.
