The Research On The Technology Of Embed Wiress Image Transimission Based On Bus

In the first, the thesis recommend the design of the technology of embed wireless image transmission based on bus. Using DSP and CPLD as cores of the hardware construction, in this scheme, the image collection is dominated by the programmable chip CPLD and the image prccessing is implemented by DSP, thereby the superiorties of the different types of the programmable chips are exerted, the cost price of the system is reduced, the volume of the product is minished, the performance of the system is enhanced.In the thesis introduces a fast arithmetic,Loeffler arithmetic and its realization on DSP. A fast arithmetic in DCT based on DSP is put forward and implemented. Compared with the Loeffler arithmetic based on DSP, it saved 25 percent time approximately.In the central server design, the communication protocol between he server and radio terminals is given. The server software is also designed and implemented by an application of multithread mechanism. In the last, the papers analysis the problems that can be improved in the system.
