AMD's Jaguar to Support AVX
A note posted by an AMD developer suggests that the Kabini processor, a 28 nm mobile chip that will integrate the Jaguar processing core, will support Intel's AVX instruction set, as well bit-manipulation instructions (BMI).
The quote:
"We are expecting some changes to tunings and costs. We will update them in near future. There are ISA changes as well like btver2 supports AVX, BMI."
It was recently reported that AMD scrapped SSE5 in favor of AVX, which is likely to also introduce SSE4 in Jaguar. Jaguar's predecessor Bobcat only supports SSE3.
Kabini is expected to be released in 2013 as a low-price and low-power mobile processor with up to four cores and a power envelope spanning 9 to 25 watts. The program of the upcoming Hot Chips 24 conference in Cupertino indicates that AMD will be revealing more information about Jaguar at the end of August.
Supporting SSE4.1 and 4.2 is a good move, but will it make for a far more complex core?
And yet another reason to hold off on purchasing another laptop... again.
Oh man, I havn't thought of Assembler in decades. Thanks for reminding an old programmer about the good times. Now to read up on the SSE4.1 ops for an asm fix.
Jaguar is a low powered x86 CPU or APU for tablets.
Trinity already supports SSE 4.1, SSE 4.2, SSSE3, and probably AVX, but I don't know if it supports BMI. Excluding BMI, I also know that Bulldozer supports all of these and that it might support BMI. I'd have to look up BMI support to know that one for sure.
It's not like there is such thing as a high performance, very low power and low price CPU, especially in mobile markets.
Bulldozer supports SSE4a so I'm very much interested in what these BMI instructions are; I can't find any reference to an instruction set. If AMD indeed have worked on one, it'd make a lot of sense to implement it into the Bulldozer design especially if they're sticking with starving their cores for work.
*Temesh* looks very interesting, too ...
