The design of a CMOS sensor camera system for a nanosatellite

[摘要] This thesis relates to the design of a camera system for a nanosatellite based ona CMOS image sensor. The design specifications and constraints are consideredfollowed by the proposal of a versatile design with all the required functions imple-mented on a single FPGA. These functions include bad block management, datarouting, an EDAC, a soft-core processor, glue logic to external devices, and com-munication busses.The Altera Nios II soft-core processor is implemented in this design, which en-ables simple changes to be made in software. A good mixture of intellectual prop-erty soft-cores, open-source cores, and user created logic are utilised in this broadbase design, containing a combination of hardware, digital logic, and software.Low power and compact devices are selected for this design to minimize thepower usage and the physical size of the camera system. The system's peak powerconsumption is 952mW which is below the required maximum consumption of 1W.This design's performance is therefore ideal for a subsystem onboard a nanosatel-lite.
