MIPI CSI Device Controller
MIPI CSI Device Controller
The VS_MIPI_CSI2_DEVICE is a CSI-2 device-side controller that implements the CSI-2 protocol for transmitting data to a CSI-2-compliant host, targeting chip-to-chip communication in mobile systems. It is fully compliant with the MIPI Alliance Standard for CSI-2, Version 2.1, and supports both D-PHY (up to 4 lanes) and C-PHY (up to 4 trios) interfaces, with configurable PPI widths to accommodate high-speed and low-power operation. The controller also offers configurable pixel throughput (4 or 8 pixels per cycle), supports a wide range of image formats (including YUV, RGB, RAW, and others), and provides multi-virtual channel identification and processing for efficient multiplexing of multiple data streams.
