Design And Implementation Of Signal Acquisition System Based On DSP TMS320C6678

Since entering the 21 st century,with the rapid development of electronic information technology,the high speed data processing speed and real time puts forward the new challenge.A higher challenge,prompted the DSP to multicore,compatible with fixed and floating point,high frequency of kernel,such as a number of wide direction.As the data processing of DSP algorithm of computing scale geometric growth,traditional single chip DSP system cannot meet the application requirements,in some real time capability is strong,large amount of data processing of special applications,building more nuclear DSP high speed information processing system is the best solution?Eight nuclear DSP processor,this thesis analyzes the TMS320C6678 was studied with the processor and FPGA as the core to build the design scheme of high-speed information processing system,and to realize a eight channel signal acquisition system for radar signal acquisition.This thesis briefly introduces the hardware design,focusing on the analysis of TMS320C6678 SRIO high-speed bottom interface,etc.On this basis,according to the actual needs of subject completed the multi-core DSP Boot startup software design,SRIO communication between DSP and FPGA software design,SGMII gigabit network communication software design,multi-core synchronous communication between software design and the SYS/BIOS application research of real-time operating system design;Write the underlying driver software interface design,realized the radar signal acquisition and processing of signal acquisition system?System designed in this thesis between the PC and signal acquisition system depend on gigabit network interface to the function of interactive data.PC under various parameters control command,signal acquisition system is to deal with these commands and upload the signal data collection and processing.Complete the whole of the system software of the interface function testing and validation of the overall system performance test,and the system has been delivered to a certain institute to try.
