Client-side telephony chip simplifies integration
A new CST (client-side telephony) chip from Spirit is designed to solve the problems encountered when implementing speech compression, datacommunication and telephony functionality into new devices.
Spirit's MP3 codec is proven to show the highest performance on ARM platforms (peak resource consumption is less then 10MIPS).
This feature has made it possible to achieve less than 45mW total system power consumption while playing 128Kbit/s MP3 on the chip, providing significantly longer battery life for the end-users.
"ARM is at the heart of this digital music player revolution providing the 32bit RISC processors that power both the user experience and the multimedia playback", said Rob Coombs, Director of Mobile Solutions at ARM.
"The high-quality software solutions that companies like Spirit are developing, highlight how compelling the ARM platform is for portable media player applications".
SigmaTel is the largest supplier of MP3 players and audio chips to the consumer electronics market.
Its Portable Multimedia SoC is currently the number-one Flash-based solution in the MP3 player segment.
More than 300 player designs contain SigmaTel solutions.
Apart from remarkable sound quality, Spirit's MP3 codec provides extremely high robustness to damaged MP3 bit streams and very low MIPS and memory requirements.
As a result, the end user will hear and feel dramatically clear and high-quality noise-free audio while listening to voice data or music on a portable device.
SigmaTel Portable SoC solutions empower device manufacturers and designers to create portable multimedia products that go beyond today's ordinary MP3 players.
SigmaTel SoCs can be found within the newest MP3 players made by Creative, Disney, Lenovo, Memorex, Oakley, Philips, Samsung, Thomson and many others.
"Next generation SoC developed by SigmaTel turns out to be an excellent solution for all modern mobile devices like digital audio players, PDAs, portable video players, and many others", said Andrew Sviridenko, CEO and Founder of Spirit DSP.
"We are glad to have made a valuable contribution to SigmaTel's world-known products".
"As for us, Spirit will continue to extend its reputed portfolio of solutions tuned for ARM platforms".
"Spirit already offers advanced low-resource 3G video telephony and multimedia software for the modern ARM processors".
