Abstract


In a variety of applications in the field of digital signal processing , usually need to complete a variety of complex structure of multiple DSP co-processing functions algorithm , but facing multi-core DSP processor speed , hardware structure can not be reconstructed , memory bandwidth bottleneck , and FPGA can be provided according to the actual needs of different levels of flexibility , can be used as a good co-processor multi-core DSP processor , the system can meet the requirements of real-time , speed and flexibility . Papers the FPGA dual DSP hardware platform to achieve the target tracking system , the image processing unit . In order to complete the design of data communication , image preprocessing and eliminate like spin processing , and the final completion of the verification of each module and system debugging . (1) Data Communications : including chain junction communication ( data sent to various DSP to realize the data processing , complete the data communication interface design for FPGA and DSP ) and NiosII - embedded processor UART kernel communication , dual-port RAM communications and other functions ; (2) image preprocessing and image erasing spin processing: effectively solved by the influence of noise interference or image of the image information , and display real-time status of the image due recognition low angle deflection , timeliness and poor ; can be seen from functional testing and commissioning of the system , rotary processing FPGA image preprocessing and eliminate like not only to meet the real-time requirements , but also to ensure that the image effect . In addition , the normal chain junction transmission system tracking feature to achieve and reach the tracking response time 20ms indicators of system requirements .
