Important features
　‧　Support both ISO 11172-3 and ISO 13818-3 layer III audio
　‧　Smallest size（45 K gates in logic plus 13K bytes on chip data memory, save around 50% silicon area
　　　compare to all other known designs）
　‧　Lowest power consumption（15 MHz clock with optimized data path, 50% less power consumption than
　　　all other known designs）
　‧　Straightforward user interface
　‧　Ten bands equalizer with 64 steps for -20 to 20 dB gain
　‧　Thirty-two steps volume control
　‧　Can be mapped into FPGA and run the MP3 decoding in real time
　‧　Full synthesizable technology independent verilog RTL code

MP3-SO1E top level interface


　　



Why MP3-SO1E is the best choice for certain applications?
In general MP3-SO1E saves around 50% power comparing to all the known RISC and DSP solutions because MP3-SO1E uses lower system clock and optimized data path.

Integration concern  
 MP3-SO1E has straight forward interface for system integration. The integration of this decoder takes days instead of weeks.

Case study
　‧　Most PDA can run MP3 decoding software with a acceptable performance. However if you try to listen to the
　　　music while running other program, you will often hear an annoying  noise. MP3-SO1E is the excellent choice to
　　　off load MP3 decoding function from CPU.
　‧　DSP processor inside the mobile phone can be used to handle MP3 decoding function, but it has the same
　　　problem as PDAs. By integrating MP3-SO1E into the mobile phone base band processor, the phone is capable
　　　of playing quality MP3 music anytime.
　‧　With MP3-SO1E and a modem connected to the local music shops, audio on demand system could be built
　　　with very low cost. 
　‧　MP3-SO1E is no doubt the best solution for Bluetooth, 802.11b enabled wireless audio devices.
