Abstract

A system and method for real-time data transfer on a system-on-chip (SoC) allows MIPI-CSI (camera serial interface) data received on a first interface to be output on another MIPI-CSI interface without using system memory or delaying the loopback path. The system includes a CSI receiver, a loopback buffer, and a CSI transmitter. The loopback buffer is used for the data transfer between the CSI receiver and the CSI transmitter. The CSI transmitter receives a payload included in a data packet from the CSI receiver by way of the loopback buffer. The CSI receiver communicates a packet header of the data packet to the CSI transmitter. The CSI transmitter reads the payload from the loopback buffer based on the packet header and at least one of a buffer threshold capacity and payload size.
