He aha te mea he microprocessor? momo o microprocessors

hangarau rorohiko taea ki tatou te mahi ki te tōtika nui. Ko ratou katoa te mahi? E āwhina ana tēnei i te whānuitanga o ngā whakaaro, me ngā pūnaha rerekē. Na tetahi o ratou ko te microprocessor. He aha te mea te reira? He aha e ona mahi? He aha e nga āhuatanga o tenei pūrere? He aha te mea he hoahoanga microprocessor? He aha tawhā tei runga te reira?

He aha te mea he microprocessor?

Na ko te whakaaro, te mana nei i te pūmanawa. Ko tōna mahi - tukatuka o ngā mōhiohio mamati me te whakahaere o tenei tukanga. kia mana microprocessor iti, engari i te wa taua mahi. Mai i tenei mai te reira ake he maha o ngā āhuatanga, ka e kia whakaahuatia nei. Whakatinana i runga i te microprocessor (taikaha) o nui iahiko integrated ((C) bis), e ai kia maha ngā mongamonga. He motuhake ki a ratou:

1. (Pā ki production papatipu) utu iti.
2. tapatahi ahumahi (kotahi hangarau);
3. e te reira i ake iti wāhi (i te torutoru henimita tapawha ranei ara mitamano).
4. tika High.
5. Pau iti pūngao.

pūrere microprocessor tino tei runga i te hanga o ona hoahoanga. Next, ka kia tonu reira me raro Tuhinga ka kia arotakengia reira e toru ngā momo.

mahi

Ko tenei no te mea o ta ratou e e whakarato. Ko te kupu, te mahi microprocessor:

1. Pānuitia ka wetemuna whakahau e haere mai i te mahara matua.
2. Ua farii a tukanga tono i te whāurutau e pā ana ki te mahi o ngā pūrere waho (pononga).
3. Pānui raraunga i te mahara, me rehita TR.
4. Waihanga tohu mana e rere mā ētahi atu kōpuku me poraka rorohiko whaiaro.
5. Tukatuka i te raraunga, me te hanga i to ratou urunga ki te mahara matua, me te rēhita o ngā pūrere waho.

āhuatanga Main o te microprocessor

I roto i te katoa i reira e wha:

1. Moka.
2. Mahinga.
3. Ko te pūnaha whakahau.
4. Ko te rōrahi o te mahara addressable.

rōpū microprocessors

Ko ratou e toru:

1. CISC. He he he huinga tonu o whakahau.
2. RISC. He he he huinga ako iti.
3. Noa. He he he huinga iti o whakahau, engari i te tere tiketike rawa hoki tenei piha o ngā pūrere.

Microprocessors pērā i CISC

ai ratou mahi hei wāhanga o te whatunga rorohiko. Ano hoki i reira ko te pea o multitasking me mahara tiaki. Ko te microprocessors o tenei momo e taea te mahi i roto i te rua aratau: tūturu me tiaki. Ko te tuatahi e āhei hoki maha-tasking, me uru tika ki pūmahara atu. I tua atu, kua tiakina reira i whai kāore. I roto i te aratau tūturu hanga hae o te microprocessor 8086 me i reira ko te mahi kotahi-tukanga.

momo Microprocessors RISC

E noa ratou nga whakahau tino whakamahia. Ki te tika, te mahi te tahi mea matatini hua "huihui" te taumahinga tika. I te whakahau pau anake huringa mīhini tetahi e tika ana ki te mahi whakarara, me o ratou whakapanga. No te whakarite, i roto i te CISC i runga i te iti haere te hunga i rite wha.

He aha te mea he microprocessor?

tāutuhia te reira e rua nga wahi:

1. Whakahaere. Kei roto te reira i te kōwae mana, arorau tauhanga me te mahara microprocessor.
2. Atanga. Kei roto te reira i rēhita wāhitau, tauranga, me te mania mana pahi, me whakahau poraka.

Nui ko te hoahoanga - te whakahaere arorau o te microprocessor, e whakatau ona āhuatanga, ngā āhuatanga me te pea o te hanga i te pūnaha rorohiko e hāngai ana i runga i tenei pūrere. E toru ngā momo matua: CISC, RISC ko Noa (ko tenei ki te kōrero tatou e pā ana ki ngā pūrere ao). Na, i ratou e rave rahi ngā rōpū o rēhita e whakahaere ki rerekē nekehanga o mua. Tenei e āhei ki a koutou te mahi ngā mahi mooni "pipelining". Tenei he pānga pai i runga i te mahi whai hua. PC microprocessor tikanga tavini kotahi anake wae - hei tauira, he papapātuhi.

architecture CISC

Complex Rorohiko Tautuhi ture - oti tohutohu mo te rorohiko. Kua whakapumautia taipitopito o te microprocessor ki te hoahoanga:

1. E ratou he maha nui o whakahau, e kua kitea e ratou taumahinga, roa me te hōputu.
2. pūnaha Various whakatutuki.
3. Reira kapa waehere matatini.

He aha te mea tenei microprocessors hoahoanga? He whakaaro matatini, te arotahi matua o te mea i runga i taumahinga enei.

RISC hoahoanga

Iti Instrucktion Tautuhi Rorohiko - kākahu tohutohu mo te rorohiko. Kua whakapumautia taipitopito o te microprocessor ki te hoahoanga:

1. Ka whakamahia e te momo māmā o whakahau pūnaha: whai ratou katoa te hōputu taua ki te pūāhua ohie. Ko te raraunga i te RAM ki te rēhita o te microprocessor me te tumuaki oho hurihia e tohutohu utanga.
2. Ahakoa te tere tiketike e taea whai microprocessors raraunga te auau karaka āhua iti, me te tohu o raro o tuitui o te ara iahiko VLSI.
3. Tono hua iti te ahotea i runga i te RAM.
4. Ko ngā hōtaka mahi patuiro i runga i RISC he nui atu uaua atu i roto i te CISC.
5. Ehara i te mea e taea ki te whakamahi i te hōtaka taua ki te CISC.

architecture Noa

Ture multipurpose Tautuhia Rorohiko - multipurpose tohutohu mō te whakahaere i te rorohiko. He he whakamātau ki te whakakotahi i nga painga o CISC me RISC. Here, huihui te turanga huānga kei i ngā wāhanga takitahi (e maha i ngā i roto i te whare kotahi):

1. Ko te wahi matua. I runga anō i te hoahoanga o RISC.
2. Ko te wahi whakawhānui. Ko reira tūhono whakahaere ROM mārō.

riro i te pūnaha nga āhuatanga o te CISC. Na, kei te rere nga whakahau taketake i runga i te pūtake whakaratohia e RISC. I te wa ano i reira he he toronga, e "hanga" te mārō. Pūtake RISC mahi nga whakahau katoa i roto i te huringa kotahi. Na whakamahi te toronga te huinga matatini o whakahau. Nā ki te aroaro o ROM faaore te rerekētanga o mihini RISC, ka whakaemi i te reo taumata-tiketike te waehere o te mahi, kei te kua wetemuna reira me tuwhera ki te kaihātepe. Ko te aha microprocessors me taua āhuatanga kia whai ratou i roto i ngā o te hoahoanga o ratou hanganga.

mutunga

He aha te mea te microprocessors me e takoto i te ngakau o ratou mahi - kua arotakehia matou. O te akoranga, ki te matau i te mita katoa o enei whakaaro, e hiahia ana koe ki te horo'a i te rota o te wā, me te kore mōhio ki te pukapuka, me te kohinga o kauwhau. Ko te pūtake, ko te kua reira.
