I want to optimize design of MP3 player http://www.ti.com/tool/TIDM-LPBP-TCHMP3PLAYER based on C5535.
I want to use cheaper DSP TM320C5533 (the same but without FFT).
As we can see this design used codecs C55XCODECS http://www.ti.com/tool/c55xcodecs
As we know MP3 engine using FFT math. But in codec requirements in not described that FFT needed.
So i'm not sure about it.

Does C55XCODECS (MP3) require FFT in DSP? Can in work on TMS320C5533?

  • Hi Vladimir,

    I am fairly certain that the MP3 decoder software does not use the Hardware Accelerated FFT co-processor, which is not available in C5533.
    However, performing FFT operations with the C55x core is still possible and the MP3 decoder software can run on C5533.

    Regards,
    Mark
