Intel Potentially Reverse-Engineered AMD64

icypyr0 writes "Tom Halfhill, an analyst for In-Stat/MDR claims that due to similiarities in the instruction sets of AMD64 chips and the new 64-bit extensions for Intel Xeons, it is clear that Intel reverse-engineered the AMD64. However, due to the fact that the new Xeon is not an exact copy of the AMD64's microarchitecture, Intel has not broken the law. This very tactic has actually been used by firms such as AMD in the past to catch up to Intel."

    AMD will have the last laugh here. Turns out they embedded a Pink Floyd album in the code of AMD64 (a fair-use copy, as AMD had previously purchased the album). When Intel copied the code and put it in their chip, it was all AMD needed for a little call to the RIAA to pay a visit to Intel's house....

    Intel employee A: Yeah, it's on page 183 of this. Read it.

  5. They had to Reverse-Engineer it? by Anonymous Coward · · Score: 2, Funny

    Does that mean that what each AMD64 machine instruction does is not fully specified? How are we supposed to program for the AMD64 then, by using only the machine instructions that are clearly explained? Intel just missed an opportunity to invent a new behavior for the badly-explained instructions, publish a "complete instruction set handbook" for the AMD64, which people will use because AMD's handbook is unclear/incomplete, and have everyone wonder why their "AMD64" code only works on Intel.

    Everyone knows how slashdot ID #'s work.

    In a now famous episode of short sightedness, CmdrTaco said, "Slashdot will never need more than 640K IDs," and determined that slashdot IDs would count down from 640K and stop when they hit 0.

    Your ID of 15628 indicates both that you are new here, and that the end is near.
