This book work is Systems on Chips (SoC) development using FPGA based methodology, for Complex tracking systems design. Focused on High speed Image processing algorithms, implementations on FPGAs. First two chapters on Introduction to FPGA Based Embedded Systems design, Parallel Image Processing for Target Tracking, Algorithms for Focal Plane Array Seekers. Literature on relevant works available in the second chapter. Third chapter deals with Infrared Seeker Detectors for IR image processing requirements. Fourth chapter is on algorithms implementation methods for high speed object tracking. Tested for Single Instruction Multiple Data (SIMD) architecture, Sum of Absolute Difference (SAD) Algorithm, IR image segmentation, Radon Transform for Projection curve analysis and Moving Vectors algorithms for FPGA based re-programmable Systems designs. Finally on System simulation, implementation, test procedures and benchmarks are discussed.
