Simultaneous mp3 decoding, processing and TDM transmitting

Hello dear engineers.

I'm looking for optimal solution for expandable audio system project.

Could some one please direct me to coresponding type of proceesors (SHARC or BLACKFIN) wich can handle reading from SDcard or other type of storage, decoding, mixing (if necessary) and TDM transmitting simultaneously several mp3 files (16 for example).

Or maybe this project is unrealizable?

  • Hi,

    Analog Devices' SHARC processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. With multiple products variants and price points, SHARC brings real-time floating-point processing performance to many applications where dynamic range is key. Latest products provide leading performance/power efficiency and advanced connectivity with an integrated ARM® core.

    You can get more information about SHARC processors in the below link:
    www.analog.com/.../sharc.html

    New multi core processors are the latest in a growing series of high-performance, power-efficient, real-time platforms that deliver greater than 6 giga-floating-point operations per second using two enhanced SHARC+ cores and advanced DSP accelerators (FFT, FIR, IIR).

    The ADSP-SC5xx processors have the multi-core SHARC+ with ARM in the architecture. Please refer the below link for more details:
    www.analog.com/.../adsp-sc58x-adsp-2158x-series.html

    Analog devices Blackfin 16-/32-bit fixed point embedded processors offer software flexibility and scalability for convergent applications: multiformat audio, video, voice and image processing, multimode baseband and packet processing, control processing, and real-time security.

    The ADSP-BF60x and ADSP-BF70x are the new processors in Blackfin family. The ADSP-BF60x processors are the Dual-Core processor up to 1GHz with Hardware Support for HD Video Analytics. The ADSP-BF70x processors are the latest Low Power 400MHz Blackfin+ embedded processor with 1MByte L2 SRAM & DDR2/LPDDR Interface.

    You can get more information about Blackfin processors in the below link:
    www.analog.com/.../blackfin.html

    Please use the below parametric search link to choose the processors.

    We have Processors Software and Tools page provides a convenient look-up table to indicate to users what evaluation platforms, extender cards, emulators, software development tools, and middleware are available for the specific processors you have chosen to evaluate for your designs.
    SHARC          - www.analog.com/.../sharc-processors-software-and-tools.html
    BLACKFIN     - www.analog.com/.../blackfin-processors-software-and-tools.html

    If you can provide more information on other requirements from the external interfaces, the speed grade, memory requirements, package, which you are looking for, then we can help you narrow down to select the right derivative in processor family.

    We have evaluation kits available for different processors which will provide a platform for customer to evaluate our DSPs. When you navigate through our product specific page you would find its evaluation platform with associate.
