In this research, we have researched on a compiler which translates C programs to HDL programs, a tool to synthesize the HDL program for FPGAs, and hardware libraries for image processing and cellular automaton using desk top computers and CAD tools which we purchased by the budget of this research. As for the hardware compiler, we have researched on algorithms to handle structures and pointers to evaluate the compiler using more programs, arid to achieve efficient pipeline processing by avoiding access conflicts on memory banks. We have also developed an algorithm to automatically translate loops in C programs to pipeline processing on the hardware. As for the synthesis tool, we have developed a prototype, and evaluated its performance using simple HDL programs. As for the hardware libraries, we have developed the followings. In the image processing, we have developed a circuit for one dimensional cross correlation function which can be used for real-time stereo vision. We have also developed two circuits for two dimensional cross correlation function. These two circuits can be used for real-time processing of PIV (Particle Image Velocimetry) and optical flow. In order to detect objects in images, we have developed circuits to find lines based on Line Hough Transform, and arbitrary shapes based on Generalized Hough Transform. We have also developed libraries for two and three dimensional cellular automata.
