How to get an exmaple using swi,prd,tsk of DSP/BIOS on DM6437 platform?

To start with multi thread on DM6437 , are  there any examples using DSP/BIOS?

In dvsdk_1_01_00_15 and dvsdk_1_11_00_00, I can't find useful example as reference.

  • Hi,

    Thanks for your post.

    In general, the BIOS PSP software has the preview examples like, previewer and previewer_on_the_fly. Kindly refer to any of these examples which would be a good start, I guess.

    To start out though, have you tried the example in dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\system\dm6437\bios\dm6437_evm\src\video\sample\rawcapture\build?

    Likewise, for the previewer to start, please look at the example in \dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\system\dm6437\bios\dm6437_evm\src\video\sample\previewer\build\

    You can  try to use the code from "dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\system\dm6437\bios\dm6437_evm\src\video\sample\previewer_on_the_fly+

    While building the previewer on-the-fly application, you need to enable the macro "PSP_VIDEO_PATH_ENABLE". The details are available in the section 4.3 of the document

    "\psp_1_00_02_00\pspdrivers\drivers\previewer\docs\BIOS_PREVIEWER_Driver_UserGuide.pdf".

    Also, kindly check the DM6437 workshop tutorial link below:

  • HI Sivaraj,

    Thank you for your reply very much..
    With your help ,I have created several projects successfully ,using prd,,tsk,swi.

    1、I use prd to light leds per 1 second or any time slot  I like.

    2、What's more , I can use different priorites of tsk and swi to cancel echo in audio application .

    Here are  other useful documents or books ,
