Silicon Ocean Ultra Low Power MP3 Decoder ASIC Core (MP3-SO2)

Important features

• Decode all MP3 bit streams under 10 MHz Clock, an impossible task for RISC/DSP based architecture.    

• 55 K gates in logic plus 13K bytes on chip data memory, no program ROM needed.

• Straightforward user interface.

• Hand-crafted optimized data path with completely hard-wired logic.

• Fully synthesizable technology independent of verilog RTL code.

MP3-SO2 top level interface

 

 

 

 

 

   

Why MP3-SO2 is the best choice for certain applications?

In general MP3-SO2 saves more than 50% power comparing to all the known RISC and DSP solutions due to its lower system clock and optimized data path.

 

 

Integration concern 

 

MP3-SO1(2) has straightforward interface for system integration. The integration takes days instead of weeks. 

 

Case study

• Most PDA can run MP3 decoding software with an acceptable performance. However if you try to listen to the music while running other program, you often hear an annoying  noise. MP3-SO2 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-SO2 into the mobile phone base band processor, the phone is capable of playing quality MP3 music anytime.

• With MP3-SO2 and a modem connected to the local music shops, audio on demand system could be built with very low cost. 

• MP3-SO2 is no doubt the best solution for Bluetooth, 802.11b enabled wireless audio devices.
