Central evolution of processor
The first microprocessor since the dawn of human civilization, the 4004th company of Intel, in 1971, combined about 2, 000 transistors offer the unprecedented level of the power that calculate for time. It reforms PC World completely through taking the computer that can be born to masses’ place. Today, the processor core combines the exceeding of 20 million transistors, support and consume billions of transistors and hand over 30 with the high-speed buffer memory, 000 x more performance are nearly the memory than these 4004.
8 processor core load pipeline simple machine of line with even in will it be will it be the beginning the seventies the 20th century. Make one main step 80386 these, one can deal with gigas of byte suitable for high-performance exhaustive 32 machine of memory of work station. Later, 80486 was posted with an engine that comprehensive flow is lighted together.
Not over to high-performance seeking. At the beginning of 1990s, Intel Pentium processor realized a superscalar processor, successful with Intel processor of Pentium Prso, this does it to the inferring central and positive change of processor out of order. It causes deep Pentium 4 processor central greedy food containing pipeline thread in multigigahertz frequency to performance that the appearance of more application and arrival of Internet bring Desire. Subsequent Intel core and core 2 processors establish the equilibrium between performance and consumption.
Reduce ability
From early PMOS to NMOS, all these things are results that silicon technology evolves, in CMOS at that time, reduce power. Technology finalizes the bid to make the quantity of the transistor realize these complicated buildings on a gap regularly, but well keep motive force in limiting.
In history, performance king, until frequency of utilization pay whom performance remove a few years ago alone we of change that at all costs. This is only strength begun to increase because of the expenses. It means its seepage will increase too, this is not a kind of good choice to increase the transistor frequency. This is that a current processor core has reason why lower frequency reduces the consumption, but they still hand over higher calculation performance.
Push performance
How far can you push a singly central performance? Usually, the consumption has performance to increase quadratically. Performance i.e., it if enable you, when ’s good power the the quadruplesot one limited with power you then.
So, the arrival of multicore building, you extend more cores and hand over high performance instead of making the single core greater. Performance and ability of a multicore building only increase linearly, make many cores become a kind of attractive choice on a gap. This trend will continue in the future that can foresee.
So long as you can utilize many cores to increase the performance of employing, it will continue. Can sure that exceed many cores to a application of single restriction of parallelizing; After some time, reduce back. But have you can utilize, such as task horizontal dual character and application level more dual characters of dual character. So multicore trend will continue, until you have already fully utilized homogenous multicores. Different multicores is another possibility, the large and small core coexists there, core of application stipulating for the flexibility choice increased. But such a one system may difficult the design.
Finally, don’t get rid of and integrate it as multicore part of system special-purpose and centrally. These cores will be designed and handed over ultra high performance in the low consumption by a concrete task in the heart. For example you can imagine one special-purpose core optimistic only for video go on encode and decipher or suitable for network punish. Because of having common central special-purpose and central and different integration that employs specifically, the processor will seem to be like SoC. This will have a very strong system of application in future of great appetite.
