Silicon Ocean MP3 decoder ASIC core (MP3-SO1E)

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

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.
