The Design And Realization On Little Target Detecting System Of Infrared Image Based On SOPC

With the rapid development of semiconductor technology,more Logic resources are integrated in Field Programmable Gate Array(FPGA).Especially,the birth of platform FPGA in which embedded MPU makes it possible to design a System of Chip on FPGA,which is called SOPC as well.Compared to board-class system,SOPC stands out because of its little power dissipation,little volume, much reliability,reconfigurable etc.While compared to customized SOC,SOPC has much advantage,such as save developing cost and time,hardware and software re-programmable,flexible etc.So,SOPC becomes popular in electric design domain nowadays.It was to research of infrared image based on sopc under the application blackground of precise controlling & guiding missile.Little target detecting system is a important portion of precise controlling & guiding missile information processing system.In this paper,it researched DPA arithmetic firstly,analysed its characteristic and required resource.And then brought forward SOPC solution of little target detector based on Virtex-4 FPGA in which was embedded PowerPC405 MPU hard core.And took advantage of software & hardware designing simultaneity technology and IP core reusing technology,completed the design of little target detecting system.According to the debugging result,the little target detecting system based on SOPC realized real-time detecting successfully,whose performance met the desire of precise controlling & guiding missile information processing system.
