Zusammenfassung:This paper describes a system for one-step compilation of image processing (IP) codes, written in the machine-independent, algorithmic, high-level single assignment language SA-C, to FPGA-based hardware. The SA - C compiler performs a variety of optimizations, some conventional and some specialized, before generating dataflow graphs and host code. The dataflow graphs are then compiled, via VHDL, to FPGA configuration codes. This paper introduces SA - C and describes the optimization and code generation stages in the compiler. The performance of a target acquisition prescreener (ARAGTAP), the Intel Image Processing Library, and an iterative tri-diagonal solver running on a reconfigurable system are compared to their performance on a Ppentium PC with MMX.
