In this presentation, Toerne explores high-bandwidth cameras and their application to multi-camera and embedded systems. He presents solutions for machine vision applications, focused on the use of PCIe as a camera interface for embedded and untethered applications. He examines the current and future state of PCIe speeds and connectivity, with examples of available and upcoming hardware. Camera users implementing high-speed or multi-camera applications will learn how a PCIe interface is useful for design, build and implementation of these systems.
