Abstract

This paper presents a C library for the software support of single precision floating-point (FP) arithmetic on processors without FP hardware units such as VLIW or DSP processor cores for embedded applications. This library provides several levels of compliance to the IEEE 754 FP standard. The complete specifications of the standard can be used or just some relaxed characteristics such as restricted rounding modes or computations without denormal numbers. This library is evaluated on the ST200 VLIW processors from STMicroelectronics.
