SiTel Offers uClinux on Its High-End CAT-IQ Baseband ICs


Open-source OS on a powerful 16-bit platform reduces development costs and time-to-market for high-performance telephony applications

Hertogenbosch, The Netherlands, February 19, 2008 - SiTel Semiconductor today announced that it has ported the uClinux open-source operating system to run natively on its 240 MIPS SC14450 CAT-iq baseband processor. The move makes SiTel one of only a few companies to offer the popular and free-to-download uClinux OS on a 16-bit platform, enabling cost-effective yet high-performance solutions. By taking advantage of the wide array of open-source applications already written for uClinux, SiTel's customers can further reduce development costs and time-to-market.

"We are committed to offering best-in-class telephony semiconductor solutions to enable our customers to build applications that deliver excellent performance," said Mark De Clercq, Product Marketing Manager at SiTel. "Combining uClinux and its extensive open-source application library with our powerful, cost-effective baseband allows our customers to develop new products and enter new markets more quickly and with a lower investment."

uClinux is the most popular open-source operating system for embedded applications. It is a derivative of the familiar Linux OS tailored for use on microcontrollers without Memory Management Units (MMUs). This versatile OS has been successfully ported to numerous platforms, and has been used by a wide community of engineers and programmers for almost ten years. It is also supported by extensive (C-language) libraries.

SiTel have ported the latest version of uClinux - based on the Linux kernel release 2.6 - onto the 16-bit CompactRISC(TM) processor at the heart of its powerful SC14450 baseband processor. The OS is delivered to customers as source code supported by a complete software development environment, test plan and full documentation.

About the SC14450

The SC14450 CAT-iq baseband uses the company's proven multi-core architecture to deliver 240 MIPS of processing power. It features a 16-bit CompactRISC(TM) processor, plus two user-programmable Gen2DSPs. In addition, the SC14450 supports a variety of external memories and features an integrated class D amplifier, power and battery management options, a white LED driver and a wide variety of peripheral interfaces including master / slave PCM, UART, SPI, dual-access bus and USB 2.0.

Its range of components enables the creation of high-end cordless CAT-iq handsets and basestations, Integrated Access Devices (IADs) and wired Voice over Internet Protocol (VoIP) telephony applications. A hardware development kit for the SC14450 is available.
