Larrabee Based On a Bundle of Old Pentium Chips

arcticstoat writes "Intel's Pat Gelsinger recently revealed that Larrabee's 32 IA cores will in fact be based on Intel's ancient P54C architecture, which was last seen in the original Pentium chips, such as the Pentium 75, in the early 1990s. The chip will feature 32 of these cores, which will each feature a 512-bit wide SIMD (single input, multiple data) vector processing unit."

    I was about to ask "Since when is the x86 instruction set optimized to run general computing?"

    Then I noticed that the word was "adapted". Yeah, that's fair...

    Seriously: The x86 (inspired by the hardware driving Datapoint's early smart terminals and previous chips for building hand calculators) was contemporary with Motorola's 68x (inspired by Gordon Bell's masterfully engineered PDP-11 and VAX instruction sets). While a lot of good people have poured their hearts and souls into turning it into a silk purse, and the original sows were particularly good examples of their breeds, the x86's descent from a pair of sow's ears is still apparent.

    You might want to keep the lock prefix for this kind of application. And the P54C didn't have BCD arithmetic - it had BCD load and store operations which translated to binary floats internally. You got the precision of binary floating point arithmetic and the storage density of BCD. Something only an Intel engineer could invent.
