Optimization of Embedded Linux systems without FPU
نویسنده
چکیده
1 Linux is a popular operating system for embedded systems. Some embedded systems use processors without floating point accelerators (FPA) or floating point units (FPU), in order to satisfy cost and power consumption requirements. This paper describes and compares optimization options for software implementation of floating point operations on systems without FPA or FPU. Our results show that software approximations perform very well, even when compared to systems with hardware FPA or FPU. Software approximations to IEEE standard floating point can be used in many important applications, such as cell phones, games, etc.
