Design, Dsp-based Airborne Video Recorder

A design of video recorder for aviation based on DSP is presented . The design process of a integrated prototype using C6202 DSP of Texas Instrument is described.High speed DSP device is used as the core processor of this prototype and FLASH memory is used as the storage device. Video data will be compressed using motion picture compression technology before they are stored.Comparing with the traditional recorder which uses magnetic tape as the storage device,this design is smaller in size and steadier.The function of the hardware modules of the system is described and the technique I used to realize it is discussed.The data compression algorithm based on MPEG is presented and the method I used to optimize the code is described in details.At last,the test results are presented.
