The core is made of five main parts. The lane management together with the packet engine receive parallel byte lanes, extract control information, implement lane alignment and byte reordering, and finally provide aligned payload byte streams. The pixel unpacker extracts pixel data types out of these byte streams. The output pixel clock adjustment converts the pixel stream into the output clock domain. The control interface contains a set of control and status registers accessible by a CPU using the AXI4-Lite slave interface.

MIPI CSI-2 IP Core Description

Image sensors with MIPI interface are not only used in mobile phones, but also in industrial and automotive applications. These applications often require an FPGA for control and further processing. This IP helps to interface MIPI sensors of different vendors to FPGAs. The IP relies on an existing D-PHY implementation, typically available from FPGA vendors. The IP is delivered as a fully functioning reference design that is running on an agreed common delivey platform along with a MIPI FMC module compatible with S2I’s MVDK and standard FPGA evaluation kits. Together, they provide an easy way to design a camera.


Delivery

The IP Core is delivered with a complete reference design for S2I’s MVDK with a Zynq7 or Ultrascale+ FPGA and an IMX MIPI FMC module. Since the physical interface is abstracted by the AMD D-PHY core, it is easy to port the design to other FPGA platforms like, for example, the 7 series AMD FPGAs.
