Abstract

This paper presents a design environment which enables fast simulation of fixed-point signal processing algorithms. In contrast to existing approaches which use C/C++ libraries for the emulation of generic fixed-point data types, this novel approach additionally permits a code transformation to integral data types for fast simulation of the bit-true behavior. A speedup by a factor of 20 to 400 can be achieved compared to library based simulation.
