Ke kālailaiʻana i keʻAno a me Speed ​​o ka CPU unu lawelawe

Unu lawelawe hiki e manao like i kekahi o ka mea nui loa o ka'ōnaehana. He He hapa ia e leie aku wikiwiki no ka mana i ka poʻe i lawe mai ma ke kahua. ʻO nā unu lawelawe i kēia manawa, ua hoʻomohala i nāʻano a me nā pihana'ū. Ka loa kēia a me ka mea hou loa nā unu lawelawe i ka mea e loaʻa i loko o ke kuai i ike like 5th hanauna. ʻO nā unu lawelawe i mau ike a me ka palapala e like me CPU. Ke CPU ku no Central aaioee Unit. Ka unu lawelawe Ua i loko iho me ka lākou o ka olelo i keia manawa, mānewanewa oiai ka mea, e ulu. ʻO keʻano o ka hanaʻana e like me walaʻauʻana IO oihana, Logical kumu hoʻohālikelike a, a mawaho Lako e noho mana ana ma keia mahele. Ma keia hōʻike aʻo i keʻano, a me ka māmā manao paa o na nā unu lawelawe me ka manao i ka OS e e hana. No ka mea, a pau nā mea hoʻohana i mea oleʻenehana savvy keia hōʻike aʻo i mea he naauao nui i pili i ka mea malalo iho o ia mea.

Part 1 pono o ka CPU

Ma hope mai nō kekahi o nā pono i i pili i nā CPUs. Aka, ia mea,ʻaʻole e hiki ke kakau iho i na lāliʻi ma keia hapa uuku wale no, akā, no ka nui pros i oleloia:

Part 2 ka manao o ka CPU

CPU mea nae he circuitry i ua hoʻohana 'ia e lawe mai i kekahi mau hana. I loko o ka 'ōlelo functionality moe i ka hardwired kau o Logical olelo ao i ka poe i ike i ke aʻoʻia. Mau olelo i hana i ke kumu o ka mana i ka poʻe i lawe mai ma ke kahua. Ua nā Oae, subtraction, hoʻohālikelikeʻia, a ua lele komo i kekahi 'ia paha o nā papahana. Na olelo i ka poe i oleloia e noho mana ana ma kekahi kau o ka'āpana i i noniakahi no ka ia. Ma ka iaaiey'ōlelo ka mea, ua ike ia ka opcode, a no ia mea, ia mea i kekahi o ka mea nui loa. Ke CPU decodes ka opcode e hōʻoia 'ia e lawe i ke puhi ia o ka olelo ao mai. Ke CPU Hiki ke nānā pū me ka hoʻohui pū 'ia o nāʻikepili a me ka hooponopono ana. Ma ka kēia mau kiʻi i kaʻulaʻula laina hōʻike i ka hooponopono kahe, kaʻeleʻele laina nae hōʻike i kaʻikepili pele. Kēia 'ole loa wehewehe i ka CPU a me kona functionalities. Ke me kekahi mau wahi e i noniakahi loko o ka CPU i ke Alu, Na Makuahine Unit, helu huahelu. Uaki ana, a me ka parallelism nō ka 'ē aʻe e i komo i loko o ka CPU. Na ILP oa ke aʻo pae parallelism a me TLP ie, hana pae parallelism i ka loa nui hoʻohui 'ia mea i hana loko.

The design of the CPU

Part 3 ka hana o ka CPU

I ka hana ana o ka CPU hilinaʻi nui maluna o na mea he nui aʻe 'o ia hoʻi uaki uku e like me ka IPC oa na olelo ao no uaki. Eia nā kumumea i lilo i kumu o ke aʻo no ka lua a me ka CPU hiki ke hana. Ke paʻa luna kiʻekiʻe o kekahi o na kumu nui na mea e 'ole i ka hana o ka CPU. Ka wili CPUs o keia la i ka poe e noho ana i ka mea maikaʻi i loko o hua'ōlelo o ka aaioee māmā holo. Ka hoʻohui 'ia o holomua parallelism i kekahi ia i ka manaʻo o ka iki kekahi,ʻaʻohe.

Pehea e nānā i keʻano a me ka mämä holo o ka unu lawelawe

Ke kaʻina hana i ka mea hoʻohana pono e hahai i pili i ka mea malalo iho o ia mea ua wehewehe me lalo. Nāʻanuʻu i mea e e hana i oleloia ma ka au mamuli.

1. Ma kaʻoneki ka mea hoʻohana Pono e loaʻa ka My'ē ikona. He laila, e e pono kaomi 'ana e hoʻomaka i ke kaʻina hana:

The performance of the CPU

2. O ka waiwai i laila, i ka e lolouila e neʻe mua i ke kaʻina hana:

CPU performance

3. Ma ka nui loa aʻeʻaoʻao e hele mai i ka mea hoʻohana ke ike i ka unu lawelawe ikepili kemu, a me ka pili māmā. Ke kaʻina hana i na welauʻaneʻi ma ka piha:

Ke kumu o kēia hōʻike aʻo i mea e hōʻoia 'ia ka mea hoʻohana loaʻa, e ike i ke kipi ikaika o ka CPU. Mai ka aaioee ka mämä holo i ka luna 'hua'ōlelo komo i ka CPU i ua wehewehe. i nā pono o kēia papa kamepiula wahi e wehewehe. Ke CPU Ua kanalua i ka papa kuhikuhiE hapa o ka'ōnaehana, a no ia mea, ia mea nui loa i ka noonoo, a aʻo ia. Ke kaʻina hana o ka loaa i ka CPU māmā a me ka 'ano mea i hōʻikeʻia aʻela koʻaneʻi hiki ke hoʻohana' ia kokoke i na Microsoft OS mea i ua hoʻomohala ma hope o puka makani XP.
