Compiler/TDA2PXEVM: Merge link related information Needed

Tool/software: TI C/C++ Compiler

Hi all,

I have usecase in which I have two algorithms as follows:

NullSource (A15) -> Decode -> VPE -> Sync (A15) -> Dup -> Gate_1 -> Alg_1 (DSP1) -> SgxFrmcpy (A15) -> Merge

Dup -> Gate_2 -> Alg_2 (DSP1) -> Merge

Merge -> Display_M4 (IPU1_0)

// Graphics overlay display

GrpxSrc -> Display_Grpx

At a time only one Gate will be open and corresponding output should be displayed on screen. So input to Merge link will be 1 channel always.

Will Merge link work with the single channel input and give output to display link?

Or any other link will do this functionality instead of Merge link ?

Thanks ,

Megha
