Splet30.1. Background ¶. Shared Virtual Addressing (SVA) allows the processor and device to use the same virtual addresses avoiding the need for software to translate virtual addresses to physical addresses. SVA is what PCIe calls Shared Virtual Memory (SVM). In addition to the convenience of using application virtual addresses by the device, it ... SpletZero-Copy in Jetson Image Processing Applications. If we connect USB3 or PCIE camera to Jetson TX2 via USB/PCIE interface, we need to take into account that bandwidth of USB3 or PCIE interface is limited. Moreover, when using traditional memory access, a delay due to copy of captured images from CPU to GPU memory is unavoidable.
