High-speed Real-time And Parallel System Based On FPGA+DSP

With the development of astronomical technology, telescope manufacturingtechnology and electronic technology, the astronomical field increasingly highdemand on the processing speed of the system, and how to achieve these system isdirectly related to the progress of astronomical research, therefore looking foreffective method to realize these system is very meaningful. FPGA not onlycomputing speed and parallel computing; DSP can easily and quickly realize lots ofcomplex algorithms and control. We developed the real-time and parallel systembased on FPGA+DSP to effectively realize the high-speed and real-time computing inastronomical field.After comparative study FPGA and DSP, we developed the SDIMM by usingFPGA+DSP in order to solve the contradiction between the data acquisition andprocessing of the existing SDIMM, and further demonstrated that the FPGA+DSParchitecture will become a mainstream trend solve the high-speed and real-timesystem in the field of astronomy.This thesis is divided into five parts: The first chapter introduces the subjectbackground and significance and research and development trends of domestic andoverseas of this topics; The second chapter details the architecture, superiority andfield of application about FPGA+DSP; The third chapter introduces the developmentof SDIMM by using FPGA+DSP, details how to achieve and gives some test data;The fourth chapter summarizes the thesis and gives the next job outlook.
