Optimized Table-Driven Implementation of the Exponential Function in GCC
Xuejun Yang · Computer Engineering and Science · 2007
The fast and accurate evaluation of transcendental functions(e.g.exp,log,sin,tan)is very important in the field of scientific computing.This paper presents the table-driven implementation of the exponential function in GCC by exploiting some key features of the IA-64 architecture.This work not only improves the floating-point performance of GCC on IA-64,but also guides the implementation of other transcendental functions both on IA-64 and other platforms.
