The paper introduces support of floating point(FP) data format for the Xilinx System Generator (XSG) using logarithmic arithmetic. This type of arithmetic seems to be one of the promising ways to solve FP sort of DSP problems in practice. Our 32-bit high-speed logarithmic arithmetic (HSLA) keeps the accuracy according to IEEE 754 and speed up some kinds of FP algorithms. Promising is 19-bit equivalent utilised int this paper. It offers reasonable precision for the practical use and has min.HW requirements.
