Accelerated Technology's Nucleus Embedded RTOS on Tour with this Year's Hottest Pop Stars

9/20/2002 - Accelerated Technology, the Embedded Systems Division of Mentor Graphics, announced that its Nucleus® Real-Time Operating System (RTOS) was used to develop a wireless DSP loudspeaker controller used by audio engineers to control live sound quality and management in concert arenas.

The Clair iO mastering processor from Lake Technology Limited (Sydney, Australia) has been used in tours featuring Paul McCartney and will be on the road this season with Britney Spears, the Cranberries, Creed, N’Sync, Tim McGraw and other top artists.

The Clair iO is a 2-input, 6-output loudspeaker controller that employs 40-bit floating point DSP processing for a wholly innovative approach to live sound. The iO’s innovative design is unique in its wireless network capability. Using a wireless touchscreen controller, sound engineers can move around a stadium or an arena, hear exactly what the audience will experience in each location, and make appropriate adjustments on the spot.

To build the Clair iO, developers implemented Accelerated Technology’s Nucleus PLUS real-time kernel, Nucleus NET TCP/IP protocol stack, and Nucleus PPP, point-to-point protocol. Nucleus was chosen for the iO processor because of its reliability, which is a major issue in critical audio applications.

Within the iO processor, Nucleus acts as the communications link between the various host controllers on the Ethernet control side and the DSP processors, which manipulate the audio, on the other side. The iO processor is designed so that the ARM processor running the RTOS is separated from the DSP function.

"The reliability and small footprint of the Nucleus kernel and associated networking stack is very applicable for this type of design", said Robert Day, director of marketing, Mentor Graphics Embedded Systems Division. "Coupling that with the royalty-free business model makes Nucleus a perfect fit for the Clair iO."

Bruce Jackson, vice president of R&D at Lake Technology Corporation in Santa Monica, California, said, "As project leader, I shopped around for available real-time operating systems. I was very surprised to learn that most companies wanted a stiff up-front licensing fee, in addition to a high per unit fee. It was not an appealing value proposition. I was very pleased to find that by going with Nucleus, we were able to take advantage of a clean, one time buy-out. Accelerated Technology has been a very good decision for us."

"I have been very pleased with Accelerated Technology’s Nucleus RTOS for our ARM 7 microprocessor. We have experienced excellent reliability," said Marcus Altman, software architect, Lake Technology Limited, Australia. "I was hesitant at first because I felt we could do a more customized approach ourselves, but on receiving Nucleus, we were very quickly up and running with functionality that may otherwise have taken me a year to implement. The support has been excellent."

Mr. Jackson agreed, "The whole process of integrating Nucleus into our platform was painless. The staff has been friendly, and support first class. As a result of our recent experiences with this product, I have recommended Nucleus to a number of other companies."
