Terasic D8M-GPIO is an 8-megapixel camera kit with a 2x20 pin GPIO connector interface. It includes a MIPI camera module and MIPI decoder.
The MIPI camera module captures image and sends it out in a MIPI video signal package. This packet is converted in a 10-bit parallel Bayer pattern through a MIPI decoder. The data is transmitted through a 2x20 pin GPIO connector. The MIPI camera module has built-in Voice Coil Motor (VCM) to control its focal length. Users can adjust the focus via I2C interface.
The 2x20 pin GPIO connector is the standard expansion interface widely used on Altera DE series development kits. Any main boards with a GPIO connector can interface with D8M-GPIO.
Terasic D8M-GPIO kit also includes camera capture and display reference design. It comes in two versions. One is only RTL code and the other one uses components such as Altera VIP in Qsys. It enables users to rapidly be familiar with the operation of the camera module and develop custom applications based on these examples as a reference.

The functional block diagram of D8M-GPIO is shown above. MIPI Camera Module sends the video captured to MIPI Decoder via MIPI link. MIPI Decoder converts MIPI Video Data to parallel data and output to the main board through a 2x20 pin GPIO connector. The parameters of the MIPI Camera Module and MIPI Decoder can be configured by FPGA via I2C interface. For instance, number of output pixels from MIPI Camera Modules, RGB gain, position of focus, PLL of MIPI Decoder, and parameters of Video MIPI Decoder etc.
The D8M-GPIO Package is designed for Altera DE serial FPGA board with 2x20 GPIO expansion header.
