HOW to link a IQmath lib on DSP using Codec Engine

Other Parts Discussed in Thread: OMAP3530

hi,all!

     I am using Codec Engine on omap3530.And now I want to use  IQmath.lib in my codec on DSP.I have already include the IQmath header in my source.but now I am confused by how to modify the configuration, such as package.bld and package.xs,MODULE.xdc,MODULE.xs ,to link correctly with IQmath.lib when compiling.And where should I put IQmath?

    Can anyone here help me to figure it out? Thanks a lot!

    Hi Cosdy,

    The easiest way of using DSP software library functions in the codec on DSP is to wrap the required library function/algorithm as an xDM Compliant codec using IUNIVERSAL interface to the Codec Engine. The DSP codec algorithm can also be run from the ARM side of a dual core ARM+DSP device such as a omap3530, by integrating the new codec into a codec server package that will run in Codec Engine.

    Inorder to know more about the iUniversal interface and codec packaging  please see : http://tiexpressdsp.com/index.php/Getting_started_with_IUNIVERSAL

    Hope it helps. We will be glad to help you incase you have any issues integrating a particular library function into your codec using this approach.
