2:1 MIPI CSI-2 Bridge Soft IP User Guide
■The majority of mobile image sensors and application processors in the consumer market use Mobile Industry Processor Interface (MIPI®) Camera Serial Interface 2(CSI-2). Mobile influenced products often use multiple image sensors for depth perception as well as object and gesture detection. In some cases, mobile Application Processors (AP) may not have enough interfaces to support the number of image sensor inputs required for a particular application. In other cases, the processing latency between image sensors and imaging data may be too large.
■The Lattice Semiconductor Dual MIPI CSI-2 to Single MIPI CSI-2 Bridge IP for the Lattice Semiconductor CrossLink™ devices resolves this issue by merging two video image streams from two separate MIPI CSI-2 image sensor inputs to a single MIPI CSI-2 video image stream output. This is useful for augmented and virtual reality, drone, interactive gaming, and 360°camera applications.
■This user guide is for 2:1 MIPI CSI-2 Bridge Soft IP design version 1.x.
●Features
■The key features of the Dual MIPI CSI-2 to Single MIPI CSI-2 Bridge IP are:
▲Supports MIPI D-PHY Specification version 1.1 and MIPI CSI-2 Specification version 1.1
▲Output data rate up to 1.5Gb/s/lane
▲Configurable to 1, 2 or 4 data lanes for each channel
▲Supports all MIPI CSI-2 compatible data types
▲Two output modes supported
◆Left-Right (LR) Merge –merges video data packets from both left and right channels to form a single packet for each pixel line.Data type of both inputs must be the same.
◆Virtual Channel (VC) Interleave –interleaves data between each image sensor and assigns a virtual channel ID to identify the source. Different data types within a virtual channel is also supported in this mode.
