Elmer, <full IA-32 binary compatibility for high-end servers and workstations> This point was not in dispute. Lack of binary compatibility would be a disaster. Also I would not dispute that whatever x86 support there is will be totally implemented in hardware. I would define the question as whether it is - emulation, where some form of microcode (ie instructions executed by the IA64 core) converts the x86 instructions into an Itanium compatible form - combined native, where a separate decoder for x86 instructions feeds the processing units (but probably not as efficiently as a native core would) - separate native, where an x86 core coexists with the IA64 core (but then there are memory sharing/mode switching issues).
