Enable Mp3 Codecs on BC127 Module

Hi, I am wondering how to enable mp3 codecs on the BC127 module?

Actually i am able to successfully play uncompressed data on BC127 from RAM but when i want to play data from external flash memory, speed doesn’t match with speed demanded by I2S (for data sampled at 44100, 16 bits). I am thinking of using mp3 codes on BC127 but for time being I just want to evaluate this idea.

Thanks
