I don't know what Gopher's source is but I think I remember the Intel released some diagram that shows an x86 core in the corner. I don't think that the diagram has to be taken literally. It seems more likely that Merced has a preprocessor that converts x86 instructions into IA64 native instructions in the same way that P6 converts x86 into ROPs or whatever Intel calls the RISC-like operations that the P6 core actually executes. But there is not enough information released to date to know for sure.

Re: "I don't think so. The x86 support comes from a separate x86 core included in a
corner of the Merced chip."

May I ask how you know this to be true?

Maybe from this foil.

<May I ask how you know this to be true?>

There was a photo of a Merced die plot in the October 26, 1998 issue of Microprocessor Report. On the die plot was an overlay from Intel showing the units of Merced. The IA-32 compatability unit was in the upper-left corner and took up a small fraction of the die.

Oh, and by the way, there's no reason to believe that McKinley won't have IA-32 compatibility in the hardware.
