Multi-SoC Demo Based on PCIe

Jacinto 7 SDK [3] provides a reference application to showcase multi SoC concept. In this example, three TDA4x EVMs [4] are connected using PCIe interface. First, the EVM captures camera frames and those frames are transferred to the third EVM via second EVM over PCIe. The third EVM drives the display to show camera frames on a screen.
