Want some suggestion on Algorithm transplant

Hello everyone!

  I want to move a complicated Algorithm from PC to DM8127,but I don't know what is the common way to do this.

  As far as I know,dsp is not allowed to allocate memory freely in DM8127,it seems like an input data buf is given to dsp,dsp do some work and give it to a output buf.So I guess it will be very difficult to move a complicated Algorithm directly to dsp and call it on arm via codec engine.

  And I also find C6Accell  ,which seems quite useful.It provide some basic dsp Algorithm(xDais standard),and I can call these basic functions on arm,which seems a more easy way.

  My question is which way is more commom when we use DaVinci products: a simple dsp Algorithm+a complicated arm Algorithm OR a complicated dsp Algorithm+a simple arm Algorithm.

 Please give some suggestions,thank you very much.

    It depends on the type of algorithm, not of the complexity. The DSP is designed for signal processing algorithms, communications algorithms (like FFTs), high-precision algorithms, algorithms that do searching and sorting, common video and imaging algorithms.
