The MP3 decoder generally is faster than the I2S output, so at a certain moment there will be no free buffers left. The queue system of FreeRTOS will suspend the mp3 decoding task when that happens, ...

先日「MP3ファイルを作るエンコーダは進化した? 昔と今のiTunesで比較検証」という記事を書いた。その時の結論は、微妙に進化していそうではあるが、極端な違いはなかった、というものだった。この記事を公開した後、読者から「『デコーダ側も進化して ...
Abstract: In this paper, we present a highly optimized one-chip digital audio decoder supporting both MP3 and AAC standards. The design has been focused on the hardware modularity for both MP3 and AAC ...
In the SoC design and integration methodology of a MPEG1/2 Audio Layer 3 (MP3) decoder chip, a top-down integration flow, combined with a focus on constraint-driven timing analysis, modular simulation ...
