    3.2 MIPI Decoder The MIPI camera module output interface is MIPI interface, which cannot directly connect to the Terasic FPGA board; therefore, a MIPI Decoder (TC358748XBG) is added to convert MIPI interface to a parallel port interface (See Figure 3-3). Decoder users can quickly obtain the image data and process it.
