Re: The trace cache essentially allows for dynamic reprogramming of the chip's microcode YOU HAVEN'T A FRIGGIN' CLUE ABOUT CPU MicroArchitectures

The more I think about it, the better I like the analogy I posted - I expect Intel will start using it, soon, to describe how their chips work.

The post I made was (one of a very few, from me) complimentary to Intel and praised one of the features of P4 - fascinating that we see you arguing against one of the few really great features of P4 (and Coppermine).

The trace cache maintains a set of µops that represent the chip's "machine code" that it executes when processing an instruction its formal instruction set. Microcode consists of sets of a chip's "machine code" that are executed when the chip executes an instruction from its instruction set.

What a fine analogy I came up with to describe what is probably the best feature of PIII coppermine and P4!

Once again, Paul, you leave me basking in my brilliance...

:-)

Thanks, buddy!
