Abstract

This paper presents a methodology which enables the generation of C62× optimized fixed-point C-code from a floating-point description of an algorithm. The FRIDGE design environment transforms floating-point ANSI-C code with local fixed-point annotations into an internal bit-true representation. From this representation we generate C62× optimized integer C code utilizing the code transformation techniques illustrated in this paper. A benchmark is presented comparing the efficiency of the generated code with C67× C-code, C62× floating-point emulation and generic integer ANSI-C code
