PROCESSOR-SDK-DRA8X-TDA4X: How many maximum inputs can I give to a node ?

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hello,

I am using PSDK 6.2.0.21 for the TDA4xEVM, on Ubuntu 18.04 host machine.

I have an application in which I need to pass around 15 input arguments to a node. Out of which 10 are user data objects, 3 are vx_image objects and 2 are vx_tensor objects.

Please let me know if it is feasible to make such a node.

Thank you,

Ameya.

    Ameya,

    The default limit is 16 params but you can try increasing it as well based on your need and rebuild tiovx.

    All this information is available in the TIOVX documentation. We highly recommend that you go over it before trying writing a custom node or application.

    /psdk_rtos_auto_j7_06_02_00_21/tiovx/docs/user_guide/group__group__tivx__obj__cfg.html

    Also to know the default sizes of all TIOVX objects please take a look at this file,

    /home/a0393891local/Work/PSDKRA_6_2/psdk_rtos_auto_j7_06_02_00_21/tiovx/include/TI/tivx_config.h

    /*! \brief Max parameters in a kernel
     * \ingroup group_tivx_obj_desc_cfg
     */
    #define TIVX_KERNEL_MAX_PARAMS      (16u)

    Please go ahead and try it and let us know if there are any issues.

    Regards,
    Shyam
