Besides scalar instructions, modern microarchitectures also provide support for vector instructions. They enable to treat packed inputs (typically 4 or 8) in a single instruction. The challenge is now to write vector programs to support mathematical functions like sin, cos, exp, log, · · · which efficiently exploit those vector instructions. This article focuses on the design of vectorized implementation of log(x) function, and more particularly on its automation for different formats anddoi:10.1109/asap.2018.8445102 dblp:conf/asap/Saint-GeniesBR18 fatcat:ylt3ewupirhslcatpn4e4iwyoe
