Introduction
Getting Started
Development Flows Examples





The following pipelines were tested using the smartcam firmware, which is based on the kv260_ispMipiRx_vcu_DP Vitis platform provided by Xilinx. This platform contains the following input pipeline: 

AR1335 camera -> AP1302 ISP -> MIPI CSI-2 RX Subsystem -> Video Frame Buffer Write

We optimized these pipelines to show the low-latency capabilities of this device.

For the receiving pipeline please see the Video Decoding examples.
