Camera Interface Design In SOC

The purpose of this thesis is developing a universal camera interface in multimedia chip market, expansion of the multimedia chip in the functional, to enhance itst competitiveness in marke.In this paper, the top-down design method will be adopted. The design phases include system division, writing code, functional simulation, verification, and logic synthesis. The whole project covered a complete front-end design process, and different stages in the design used different EDA tools, including NC_Verilog, Debussy, Design Compile, etc.The actual realization chapters of this paper gives you a detailed design of the camera interface's modules, which include the register configuration, definition of the TOP module, the specific algorithm module, and the asynchronous FIFO. During this design, by taking into account the speed, size and power consumption and other factors, the specific design of each module is optimized accordingly, such as the adoption of the clock gating design by considering the power. After the optimization, simulation testing and results analysis, the result of this project shows that the design of camera interface function has reached the design goals, which are to support the bypass mode, to gain a variety of error detections and interrupt generation, to support RGB565, YUV ITU601/ITU65 input data format, as well as to support the switch between any two modes during data processing.Camera interface is based on the International Telecommunication Union Radio agreement, the design is a common interface. Camera interface can support the bypass bypass mode; support RGB565, YUV (ITU601/ITU656) three types of input data model; a variety of error testing and interruption. And can be dealt with in the data to support any mode switching. So the interface is more competitive than the same type of products in the market.
