Abstract
In this thesis, we implement an SD I/O imaging card module that supports SD-mode interface to the host and the interface with a CMOS image sensor. We have successfully combined the SD I/O imaging card with the CMOS image sensor. This SD I/O imaging card system can take in pictures by its image sensor and send back the pictures taken to the host via SD bus. From the simulation results, we see that the function of the SD I/O imaging card we implemented can work accurately.
