Representations of IA-64 Instructions Based on SLED YANG Xin，ZHAO Rong-cai, QI Ning
(Department of Computer Science and Technology, university of information engineering, college of information engineering ,zhengzhou 450002,China ) Abstract:
IA-64, as a processor of 64-bits, supply more ILP ,and it stands for the developing orientation of a new microprocessor. It is very significant for automatic analyse and transform of IA-64 binary instruction streams in the realization of automatic translation of binary and reverse direction engineering based on the descriptions of computer and operating system. This paper discusses SLED and the features of IA-64 instructions,introduces the technique of the design and the implementation detailedly which the representations of IA-64 instructions based on SLED and produces the reverse tool automatically by MLTK,and give the result of the automatic disassembler. test .
