Appendix C. Itanium Instruction Set

In the body of this book, we have discussed only a carefully chosen subset of the Itanium instruction set. We have elected to present those instructions that have analogues in other computer architectures, as well as selected instructions that are distinctive to this ISA. We have biased our selection towards the manipulation of full-width data, both integer and floating-point.

We acknowledge that this ISA also offers a rich set of SIMD (single instruction, multiple data) instructions for byte, word, double word, and single-precision floating-point data. Using such instructions effectively requires a degree of algorithm development and analysis that likely deserves a more specialized book.

In addition to native ...
