  • Forum Post: Re: IUNIVERSAL_Status

    Chris Ring
    A bit of background may be needed, and the docs can definitely be cleaned up. In general, the *_Status structs (in all XDM interfaces, including IUNIVERSAL) are algorithm 'output' from a control() call. The mention of 'read only' in the doc is from the caller/app POV - the intent is...

  • Forum Post: Codec Engine on C6747?

    David Kelly
    Hello, I want to use some audio codecs from Codec Engine on a C6747 (DA830/810 without using the ARM core). The Codec Engine package I currently have is codec_engine_2_23_01, but none of the example platforms are for a C6747. Are there any examples out there that will run on the DSP only that...

    The OMAP-L137 is a ARM+DSP device with a C674x-based DSP . The OMAP-L137 is supported in CE 2.23.01. Are you able to use a newer Codec Engine release? CE 2.25.01 is the latest, and the examples have been cleaned up a bit in the newer releases (and are therefore easier to support!), so I'm wondering...

  • Forum Post: Re: vobis decode issue

    Chris Ring
    From your log, it looks like creation of the codec went ok, and 2 calls to control() succeeded, but the first process() call hangs from the ARM side. The ARM-side has sent a request to run the codec's process() call, and is waiting for the DSP to reply, but that never happens. Are you able to...

  • Forum Post: Re: How do I handle multiple Codecs with the Codec Engine.

    Anand Balagopalakrishnan
    The Codec Engine allows you to access the codecs/algorithms running on the DSP from the ARM. For an ARM developer, it abstracts the details of loading/starting the DSP, interprocessor communications, setting up shared memory, cache coherency, etc. Conceptually, CE is similar to the Sun RPC with the...

    Juliann, There are two solutions to this issue that you are facing: 1. Recommeded way: Partially link the "spdec_64x.lib" to the "spdec_wit.l64P" Example Build steps for partial linking are given below: ["Release" Settings] FinalBuildCmd=cl6x -z -l lnk.cmd...

  • Forum Post: Re: Unable to create an instance for H264 encoder

    Chris Ring
    The short answer is that the codec create params are probably unsupported by the codec. Comparing the source code (codec_engine_<ver>/packages/ti/sdo/ce/alg/alg_create.c's ALG_create() function) against your trace output, you can see the framework (CE) asking the alg how many memory tables...
