ABSTRACT
The present utility software automatically converts a floating-point digital signal processing program written in C or C++ language to a fixed-point program. The conversion is conducted by defining a new fixed-point data class and utilizing the operator overloading characteristic of the C++ language. A generalized fixed-point format which consists of the wordlength, integer wordlength, sign, overflow, and quantization mode is employed for specifying a fixed-point variable or a fixed-point constant. Thus, it is possible to simulate the finite wordlength and the scaling effects of digital signal processing programs very easily.<>
