Hi Expert,
I'm running Linux Vision SDK v03.02.00(4.4.84) on TDA2Ex.
reference usecase: "chains_lvdsVipMultiCam_Sgx3Dsrv"
Modify as below:
The usual operation display is smooth.
However, increasing the amount of DSP operations will a serious delay in the display.
How can I continue to display images without being affected by DSP delay?
Only get the left image, Capture → Sync → Dup → ipc → Sgx3Dsrv. But it has not improved delay.
sgx3DsrvLink_drv.c, Int32 Sgx3DsrvLink_drvDoProcessFrames(Sgx3DsrvLink_Obj *pObj)
In addition, add Vps_printf in the capture, dup, sync link to observe each link's system_sendLinkCmd (, SYSTEM_CMD_NEW_DATA,
The sending interval will become longer when the DSP to increase the load. Why?
Could you please give some suggestion here?
Thanks in advance.
Hi,
I did not understand your question.
Which operations are you trying to do in DSP?
Is that running on parallel or serially with Display.
Why there is ipc link in the image. It should not be there.

Hi,
Which operations are you trying to do in DSP?
DSP to do custom algorithm, it's work ok.
why increasing the amount of DSP load will a serious delay in the chains?
Is that running on parallel or serially with Display.
I don't understand this meaning?
Why there is ipc link in the image. It should not be there.
Why not? It's reference usecase: "chains_lvdsVipMultiCam_Sgx3Dsrv"
I try no ipc link is don't work.
Thanks in advance.
Hi,
The final FPS for the entire chain depend upon the max time taken by all the links.
Any chain style will have this phenomenon? (Such as series or parallel)
Why are multiple cores still affected?
Could you please provide some guide on these questions?
Thanks in advance.
