Abstract

Recently, some high-performance IEEE 754 single precision floating-point software has been designed, which aims at best exploiting some features (integer arithmetic, parallelism) of the STMicroelectronics ST200 Very Long Instruction Word (VLIW) processor. We review here the techniques and software tools used or developed for this design and its implementation, and how they allowed very high instruction-level parallelism (ILP) exposure. Those key points include a hierarchical description of function evaluation algorithms, the exploitation of the standard encoding of floating-point data, the automatic generation of fast and accurate polynomial evaluation schemes, and some compiler optimizations.
