Petz, re: Merced's x86 compatibility, Yeah, the x86 (IA-32) compatibility does bring a lot of validation headaches. But in terms of design, the IA-32 translation unit takes up less than 1/20 of the die, according to Intel's foils made public. I don't think the IA-32 compatibility was a mistake, though. If the operating system can handle it, then IA-32 code and IA-64 code will be able to run at the same time, with just a context switch between the two. This allows for an easier migration path, where a customer moving to Merced can keep all its old software, upgrade only the speed-critical stuff to IA-64 whenever they become available, and leave everything else IA-32.
