裝配線廠家告訴你裝配技術條件

　　1、生產線

　　生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)，也稱為深度生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)，是(shi)(shi)(shi)一(yi)種常用于提(ti)高CPU速度的(de)技術。CPU處(chu)理指令由時(shi)(shi)(shi)鐘(zhong)(zhong)驅動，每個(ge)時(shi)(shi)(shi)鐘(zhong)(zhong)完成生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)操作。每個(ge)周(zhou)期的(de)操作越(yue)少，所(suo)需的(de)時(shi)(shi)(shi)間越(yue)短(duan)，時(shi)(shi)(shi)間越(yue)短(duan)，可(ke)以(yi)提(ti)高頻(pin)率(lv)。生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)是(shi)(shi)(shi)進(jin)一(yi)步(bu)細分CPU處(chu)理指令的(de)操作，增加生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)級數以(yi)提(ti)高頻(pin)率(lv)。頻(pin)率(lv)很高，當(dang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)以(yi)滿馬力運(yun)行(xing)(xing)時(shi)(shi)(shi)(在單次啟動的(de)情況下(xia))，平均每個(ge)周(zhou)期有(you)一(yi)條指令，這(zhe)將(jiang)隨著(zhu)時(shi)(shi)(shi)間的(de)推移提(ti)高CPU處(chu)理速度。當(dang)然，這(zhe)是(shi)(shi)(shi)理想的(de)，一(yi)般來說，生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)系列(lie)越(yue)多(duo)(duo)，重(zhong)疊執(zhi)行(xing)(xing)的(de)執(zhi)行(xing)(xing)越(yue)多(duo)(duo)，那么競(jing)爭沖突(tu)的(de)可(ke)能(neng)性(xing)就越(yue)大，對生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)性(xing)能(neng)有(you)一(yi)定的(de)影響現在很多(duo)(duo)CPU都是(shi)(shi)(shi)將(jiang)超(chao)(chao)標和生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)技術結合在一(yi)起(qi)的(de)，如(ru)奔(ben)騰iv，生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線(xian)(xian)達到20級，快頻(pin)率(lv)已經超(chao)(chao)過3GHz。教材中的(de)經典MIPS只是(shi)(shi)(shi)5級流水。

　　2.標量

　　將(jiang)一(yi)條(tiao)(tiao)(tiao)指(zhi)(zhi)令(ling)(ling)(ling)分成(cheng)若干(gan)個周(zhou)期(qi)處(chu)(chu)。理以達到多(duo)(duo)條(tiao)(tiao)(tiao)指(zhi)(zhi)令(ling)(ling)(ling)重(zhong)疊(die)處(chu)(chu)理,從而(er)提高cpu部件(jian)。利用率的(de)技(ji)術叫做標(biao)(biao)量流(liu)水技(ji)術。。標(biao)(biao)量是指(zhi)(zhi)cpu內一(yi)般能(neng)有(you)(you)多(duo)(duo)條(tiao)(tiao)(tiao)生(sheng)產(chan)線,這。些生(sheng)產(chan)線能(neng)夠(gou)并(bing)行(xing)處(chu)(chu)理。在單生(sheng)產(chan)線結(jie)(jie)構中(zhong)，指(zhi)(zhi)令(ling)(ling)(ling)雖然(ran)。能(neng)夠(gou)重(zhong)疊(die)執行(xing)，但仍然(ran)是順序的(de),。每個周(zhou)期(qi)只能(neng)發(fa)射)或(huo)退休一(yi)條(tiao)(tiao)(tiao)指(zhi)(zhi)令(ling)(ling)(ling)。標(biao)(biao)量結(jie)(jie)。構的(de)cpu支持指(zhi)(zhi)令(ling)(ling)(ling)級(ji)并(bing)行(xing)，每個周(zhou)期(qi)可(ke)以。發(fa)射多(duo)(duo)條(tiao)(tiao)(tiao)指(zhi)(zhi)令(ling)(ling)(ling)(2-4條(tiao)(tiao)(tiao)居多(duo)(duo))。可(ke)以使得cp。u的(de)IPC>，從而(er)提高cpu處(chu)(chu)理速(su)度(du)。標(biao)(biao)量機能(neng)同時(shi)對若干(gan)條(tiao)(tiao)(tiao)指(zhi)(zhi)令(ling)(ling)(ling)進(jin)。行(xing)譯碼，將(jiang)可(ke)以并(bing)行(xing)執行(xing)的(de)指(zhi)(zhi)令(ling)(ling)(ling)送往不同的(de)執。行(xing)部件(jian)，在程(cheng)序運行(xing)期(qi)間(jian)，由硬件(jian)(通(tong)。常(chang)是狀態記錄部件(jian)和調(diao)度(du)部件(jian))來(lai)完成(cheng)指(zhi)(zhi)令(ling)(ling)(ling)。調(diao)度(du)。標(biao)(biao)量機主要是借(jie)助硬件(jian)資(zi)源重(zhong)。復(例如有(you)(you)兩(liang)套譯碼器和ALU等)來(lai)實現空。間(jian)的(de)并(bing)行(xing)操作。熟知的(de)pentium系列(可(ke)能(neng)是。p-II開始),還有(you)(you)SUNS。PARC系列的(de)較(jiao)好型(xing)號,以及MIPS若干(gan)型(xing)號等都采用了(le)標(biao)(biao)量技(ji)術。
