    ILP and instruction dependencies in the x86 ISA

    Hello. im a n00b in micro architecture (I do have basic understanding of Piplines, BUSes, branch predictions etc) - but would very much like to get a deeper understanding of instruction dependencies in the x86 ISA so I can use the knowledge to write a decent article about the Hammer architecture...

    Why Hammer doesn't need FSB?

    in a MP congiration Hammer system each processor is assigned dimms of memory to comunicate with. if a given processor asks for a memory adress that itself isn't connected to then the request goes through a HyperTransport to the processor that can comunicate with the memory module which holdes...

    Why Hammer doesn't need FSB?

    as mantioned above the defanition of the front side bus speed is the speed in which the CPU comunicates with the core logic, core logic being the north bridge. sence the memory controler is on die, you can think of the front side bus as being the CPU speed. i've heard from an AMD employ (on...

    I need a good PHP/MySQL book - Please help me select

    I've seen many books at amazon and I really cant chose! some cover more PHP with litle MySQL some the other way around... some look good and popular, but the best books i've read aren't that popular. so I need advice from some one who actually already studied PHP/MySQL I need to get a data...

    HTs take on the Future of CPU rating

    True ? I used the EV7 in-order to emphasize the problem and to avoid making compression between competing products in-order to keep the debate at the technical level and unbiased.

    HTs take on the Future of CPU rating

    You know the subject so I'll make it short: What's your thoughts of future CPU rating ? its obvious that the public won't go read benchmarks before they buy a CPUs ? and MHz alone should stop being considered as an absolute rating of a CPU. And its clear why: the average person would pick up a...

    Hammer - 67 Million transistors - 103 mm^2 die - how?

    Thanx For all the answers. :) always thought that the number of transistors has liner relation to die size... well... I better dig up some more on CPU design and stuff :)

    Hammer - 67 Million transistors - 103 mm^2 die - how?

    Here's an interview with Jerry on AMD. Intresting read. here's a quote from jerry I can't quite figure out: " The Hammer, which is an eighth-generation processor, is 103 square mm, versus our seventh generation, which is 80 square mm. [There are] 67 million transistors in the Hammer?67...

    do Diffrente processors gain Scaling diffrently (in %) on the same processs shrink?

    Thank You! not only this was a great explantion - but it turns out I was sorta right! BTW could you explain exeactly what are gate and interconnect delays ? now I think I now some of this : like Gate delay has to do with how fast the gate switchs... but Im not sure. and I know nothing on...

    How Many CPUs can AMD Make?

    Will it be able to control much greater market-share then todays 20% ? what is the current Dresden fab utilization ? I think these are big questions for AMD... any insights are welcome. Thank You!

    PM's take on the Intel Article

    Intel Makes good ALUs in fact - they make very very good ALUs! darn right amazing ones! low power low leakge extremly fast! kind of bad thier current microprocessor arcihtecture isnt even close to be as good or sufficent to feed thier fantastic ALUs... im not joking about it - most of what...

    Hammer, The Chip To Break or Make AMD?

    As I see it the K-8 is AMDs Chance to get the approval it deserves and for ever leaving the image of being second place and a follower to Intel. Performance was never the problem for AMD since the Athlon. Poor Media coverage & public awareness, notorious VIA chip-sets complains (some legit...

    why would you need to recompile code in order to execute it at 64bit?

    ok - say you have a 64bit processor that uses 32bit adresing would you be able to do the jmp as one micro-op? if you can - then 64bit adressing just killed all the preformance benfit...

    why would you need to recompile code in order to execute it at 64bit?

    As I understand a CiSC 32bit processor takes instruction at various sizes and divides them into 32bit RiSC like instructions to be executed in 32bit execution units. A 64 bit CiSC processor can execute 64bit instructions hence he divides complex instructions into 64bit RiSC like instructions...
