Research And Implementation Of Embedded High Speed Parallel Signal Processor

The development of modern electronic warfare and radar technology demands that the radar signal processing system having a higher sampling frequency,data transmission bandwidth and data processing speed.However,the conventional monolithic radar signal processor can't meet the real-time processing of the large amount of data.Therefore,using the combine of parallel processing technology an embedded signal processing technology to design high-performance embedded parallel signal processing is the key to improve the performance of the radar signal processor.Based on the requirements of SAR signal for fast imaging speed and high-precision processing,the paper designed an embedded high-speed parallel signal processing.Firstly,beginning with modern embedded signal processor technology,parallel processing technology and embedded processor interconnect technology,embedded high-speed parallel signal processing techniques are studied.Secondly,according to the research results and the actual needs of the project,this paper raised an embedded high-speed parallel signal processing design.Then,according to the designing plan,the main chip selection and circuit design of the embedded high-speed parallel signal processor were completed.Finally,completing the unit testing and system testing,the test results illustrate that the parallel signal processor has strong processing capacity,and high data throughput.
