IA-64: Difference between revisions

The first document describing the new instruction set was published by Intel in May 1999. The name IA64 was published beforehand, and some of the features were known beforehand (predication and wide-issue were discussed in December 1997 on comp.arch). Itanium processors natively supported the x86 instruction sets, but they stripped the x86 hardware emulation feature from the processor due to its bad performance. The latest Itanium processors emulate the x86 instructions with software emulation techniques ([[binary emulation]], [[binary translation]]).
