in vision_sdk\apps\src\rtos\alg_plugins have so many link but vision_sdk\apps\src\hlos\adas\src\alg_plugins poor ,so how can i move vision_sdk\apps\src\rtos\alg_plugins link to vision_sdk\apps\src\hlos\adas\src\alg_plugins ?

Hi
Why do you want to do this? Are you looking for any specific Alg plug-in?
Many of the Algorithms can only work on DSP or EVE, moving those to A15 doesn't make any sense

Hi Shiju
i have run null_src_decode_display in vision_sdk\apps\src\hlos\adas\src\usecases successful ， in this case have 6 links
UInt32 NullSourceLinkID;
UInt32 IPCOut_A15_0_IPU1_0_0LinkID;
UInt32 IPCIn_IPU1_0_A15_0_0LinkID;
UInt32 DecodeLinkID; where is this link code ??
UInt32 VPELinkID; where is this link code ??
UInt32 DisplayLinkID; where is this link code ??
i have not found in hlos , and in vision_sdk\links_fw\src\rtos\links_ipu\iva\iva_dec have DecodeLink . but i donot know links Under the RTOS directory should be use by hlos . SO i try to add some print inf in decLink_h264.c , when i run null_src_decode_display the inf i add in decLink_h264.c doesnot out. where is DecodeLink??

Hi Shuai,

Not all links will be on A15 ,

Links will be on different cores depending on hardware and drivers access .

Please have a look at the jpg image in the usecase folder to get a better idea as which link is on which core.

IPC links help in transfer of frame buffer pointers from one core to another

The usecase you have mentioned has the following img which shows the details

Hi Shuai,

vision_sdk\links_fw\src\rtos\links_ipu\iva\iva_dec

The decode and encode links use IVA hardware Hence its under iva folder of links_ipu

Hi Chetan.M
vision_sdk\links_fw\src\rtos\links_ipu\iva\iva_dec this is in RTOS also can be used by hlos?

yes, you can use the IVA (enc/dec) links from HLOS also,
please refer the below HLOS UC
\vision_sdk\apps\src\hlos\adas\src\usecases\vip_single_cam_enc_dec_sgx_display

Yes, many of this Alg links can be used from a A15 Usecases as well.
In all cases, These Alg links will be running on native DSP or EVE cores, but the same can be created and controlled from a usecase on A15 Linux.
