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 ,
