The fast and accurate evaluation of transcendental functions (e.g. exp, log, sin, and atan) is quite important in many domains. We implement a software inline function library that can be called from KernelC programming language to compute 8 typical functions on Imagine architecture. By exploiting some of the key features of Imagine architecture, we have been able to provide single precision transcendental functions that are very accurate yet can typically be evaluated to get 16 function values in between 18 and 43 clock cycles. In this paper, we also discuss the algorithms and implementation details of these functions.
