An overview of floating-point support and math library on the Intel/spl reg/ XScale/spl trade/ architecture
Cristina Iordache, Ping Tak Peter Tang · 2004
New microprocessor architectures often require software support for basic arithmetic operations such as divide, or square root. The Intel/spl reg/ XScale/spl trade/ processor, designed for low power mobile devices, provides no hardware support for floating point. We show that an efficient software implementation of the basic operations and math library routines can achieve competitive performance, and effectively hide the lack of hardware floating point for most applications.
