News Release from: Spirit DSP | Subject: MP3 algorithm
Edited by the Electronicstalk Editorial Team on 30 June 2005
MP3 algorithm runs on ARM platforms
Spirit has revealed that its MP3 algorithm is now fully compliant with ARM platforms (ARM9e, ARM9, and ARM7)
The software performs real-time audio decoding starting at a low 10MHz clock speed (on ARM9e). The new implementation fully takes advantage of ARM's DSP instruction set extensions, achieving 25% more efficiency compared with a dual-MAC 16bit DSPs. Targeted for personal audio players and recorders, HDTV, STB, digital radio, and other audio systems, Spirit MP3 consumes as low as 7.5MIPS and 17.5Kbyte of program memory.

High Tech Computer Corp has chosen TeamSpirit Mobile Voice/Video Engine to be integrated into its triband 3G phones
This outstanding performance is achieved with Spirit's unique technology that allows greatly improved efficiencies compared with conventional solutions thus achieving the industry's lowest MIPS and memory requirements.
This proprietary technology saves power consumption and prolongs battery-life in power sensitive portable applications.
Economical memory requirements leave chip memory mostly free and available for integrating other audio and voice processing algorithms thus minimising development costs and BOM costs.
All this makes the device more compact and attractive for users.
The software supports all MP3 features, including Layers 1 and 2 that extends the range of applications where it can be used and makes Spirit MP3 solution universal software for audio devices designers.
'Combined with superb CD-audio quality, low system requirements and a wide range of supported features allow the software to be easily embedded into different audio systems from wide-dynamic range reproduction systems, like home theatres, to simple MP3 players', says Andrew Sviridenko, Spirit's Chairman.
