In this paper, we design mobile camera processor to support the MIPI CSI-2 and DPHY specification. The lane management sub-layer of CIS2 handles multi-lane configuration. We propose the single buffer architecture, which the independent buffers for multi lane are merged into a single common buffer. It can flexibly manage data on multi lanes,. For a key issue for the data synchronization problem, the synchronization start codes are added as the starting for image data. We design synchronization logic to synchronize received clock and to generate byte clock.
