Sopc-based Image Rotation, Zoom In And Target Tracking System Design And Realization

With the emerging of submicron technology,the SOPC(system on a programmable chip)design will develop to be the mainstream technique in embedded system design field. Field programmable gate arrays(FPGAs) are much lower cost,much higher parallel computing speed and much more flexible,Specially,FPGAs embrace particular superiority in video and image process systems.The paper introtuced the designing proposal of image rotation,zooming and tracking system based on FPGA, used Xilinx XUP Virtex II Pro Development System and developed the memory modules.In the paper,the software/hardware codesign methodology and IP reuse technique are discussed.Based on the conception of software/hardware codesign,according to the combination of "top-down" and "bottom-up"design methodology proceeding with the construction of the hardware platform and software platform,implementing the research system.The design fully uses the IP resources afforded by EDK.The design language VHDL,design criterion and rules for IP core are studied in the paper.Input file is writed in VHDL at the behavior level to describe the research system.Reflect the advanced design concept on SOPC.The research system has Harvard architecture with two buses:IBM's industry standard OPB bus(on-chip peripheral bus)and LMB bus(local memory bus).An 32bits microprocessor IP Core(MicroBlaze) is Embedded into FPGA.MicroBlaze visits and drives the peripherals through OPB bus,implementing the functions of data storage,data processing,the digital signal wave display and serial port communication. The research system is debugged and tested,with the perfoemance analysis and conclusion made in the end.
