I have the OpenVx graph as A->B->C .Let us assume all nodes are executing on DSP and the control code is in CPU . So traditionally A,B,C will be executed frame by frame basis by bringing the data to and from CPU <-> DSP each and every time the nodes are getting executed. This will cause a significant overhead as we need to access the external memory and also frequent context switches. Can this be overcome using OpenVx frame work. can A output be accesed by B without control coming to CPU. Can this be made possible by means of data tunneling ( processing in lines ). I understand there is OpenVx Tiling extension . The whole idea here what I wanted to understand is whether output of one node be accessed by another node in the same target without control switch to the CPU ?
Can you please give your inputs?
