Precision Modeling and Bit-width Optimization of Floating-Point Applications
Zhihong Zhao, Miriam E. Leeser · 2003
We present a floating-point precision modeling methodology that can be used to develop application adaptive arithmetic precision models for variable bit-width floating-point computing. We also developed optimization algorithms that minimize the total bit-width for the application such that the output accuracy meets user-defined requirements. The methodology supports different bit-widths for different variables in the datapath.
