Abstract

. Intel is applying formal verification to various pieces of mathematical software used in Merced, the first implementation of the new IA-64 architecture. This paper discusses the development of a generic floating point library giving definitions of the fundamental terms and containing formal proofs of important lemmas. We also briefly describe how this has been used in the verification effort so far. 1 Introduction IA-64 is a new 64-bit computer architecture jointly developed by Hewlett-Packard and Intel, and the forthcoming Merced chip from Intel will be its first silicon implementation. To avoid some of the limitations of traditional architectures, IA-64 incorporates a unique combination of features, including an instruction format encoding parallelism explicitly, instruction predication, and speculative /advanced loads [4]. Nevertheless, it also offers full upwards-compatibility with IA-32 (x86) code. 1 IA-64 incorporates a number of floating point operations, the centerpi...
