hello
I guess you are using VSDK, may I know your VSDK version?
systemLinkControl() is a blocking API and that is used for sending control messages/command to each Link.
In SDK we use System_sendLinkCmd() API is send the data notification.
Ideally you should have one output Q for your Alg link on DSP and is connected to GRPX link on IPU.
please refer VSDK architecture docs under \vision_sdk\docs\Architecture for more details
VisionSDK_SW_Architecture_Details.pdf
VisionSDK_SW_Architecture_Overview.pdf
