Description: The following files constitute the main C sourcecode. The tablefiles for the transforms are omitted - they can be autogenerated from within the main program using a #define statement. Please note that these files are presented as-is for reference only, they don t contain a Makefile and might contain errors. Also note that they cannot run on the DSP in realtime without hand-made assembler optimizing. The assembler version is not presented in the thesis because it is copyrighted. If you are just looking for the source-code to an mp3 player, I suggest taking a look at some of the other freely available players with source, like amp see the link below.

Description: dsp解壓縮
IAR版本
I have written a simple program for the STM32F4 Discovery board that plays a short mp3 file flash memory. For the decoding, the fixed point version of the Helix mp3 decoder is used. The audio output driver is the one used for the Peridiummmm demo, modified to use the peripheral library provided by ST.
The audio driver has two DMA buffers and a callback function that asks a user-provided function to fill one buffer with audio data when it runs out, while the other DMA buffer is streamed to the audio CODEC. This user function decodes one MP3 frame and forwards the raw audio samples to the audio driver. As this is interrupt driven, the main function can still be used for other things.-dsp decompression IAR version I have written a simple program for the STM32F4 Discovery board that plays a short mp3 file flash memory.
