I. Gabatarwa: Menene Ramin ISA?

An Farashin ISA, takaice don Masana'antu Standard Architecture Ramin, wani nau'i ne na ramin fadadawa samu a kan mazan uwayen uwa wanda ke ba masu amfani damar shigarwa katunan fadada hardware. Asalin gabatarwa ta IBM a farkon 1980s, ISA dubawa ya zama a ma'aunin bas na tushe a farkon kwamfutocin sirri. Ya taka muhimmiyar rawa wajen kunna na'urori kamar katunan sauti, katunan sadarwa na cibiyar sadarwa, kuma modem don haɗi tare da tsarin kuma sadarwa kai tsaye tare da CPU kuma ƙwaƙwalwar ajiya ta hanyar tsarin bas.

An sami ramukan ISA a ciki 8-bit kuma daga baya 16-bit versions, dangane da motherboard ta karfinsu. Ko da yake yanzu an daina amfani da su a cikin manyan kwamfutoci na yau da kullun, ana samun ramukan ISA a ciki tsarin gado kuma PCs masana'antu inda goyon bayan dogon lokaci da hardware kwanciyar hankali sun fi saurin gudu.

Mahimman halaye na ramukan ISA sun haɗa da:

Daidaitaccen canja wurin bayanai
Ƙananan saurin bas (yawanci 8 MHz)
Daidaitawar hannu ta hanyar masu tsalle-tsalle ko masu sauya DIP
Amfani da Farashin IRQ kuma Tashar DMA

A yau, fahimtar abin da ramin ISA ya kasance mai dacewa ga masu fasaha da ke aiki da su saka tsarin, retro kwamfuta, ko kiyayewa kayan aiki na gado na atomatik. Gadonsa yana ci gaba a cikin canji zuwa PCI, PCIe, da sauran gine-ginen bas na zamani.

II. Asalin ISA: Takaitaccen Tarihi

The ISA (Industry Standard Architecture) aka fara gabatar da shi IBM in 1981 a matsayin bangarensa PC IBM zane. An tsara asali azaman bas 8-bit, ya ba masu amfani damar haɗa mahimmanci na'urorin gefe kamar firinta, modem, da masu kula da ajiya. A ciki 1984, tare da fitar da IBM AT, an ƙara mizanin ISA zuwa a 16-bit version, inganta iyawarsa don ɗaukar ƙarin hadaddun buƙatun kayan masarufi da share hanya na tsawon shekaru goma na rinjaye a cikin gine-ginen PC.

An tsara ISA azaman a layi daya bas gine, inda kowace na'urar da aka haɗa ta sadarwa tare da CPU da RAM ta hanyar sanyawa Adireshin I/O, Farashin IRQ, kuma Tashar DMA. Ba kamar musaya na toshe-da-wasa na zamani ba, ana buƙatar ramukan ISA na farko daidaitawar hannu ta masu tsalle-tsalle ko Farashin DIP, Yin saitin ya zama mafi fasaha tsari.

Tsawon mulkin ISA ya sa ya zama abin dubawa don fadada da gyare-gyare. Kodayake yawancin kwamfutocin gida sun koma zuwa PCI da PCIe, da yawa tsarin gado a masana'antu da kayan aiki har yanzu dogara ga katunan ISA don abin dogara da kuma ƙaddara aiki. Samuwarsu a yau galibi ana kaiwa hari saka, retro-kwamfuta, ko masana'antu sarrafa kansa kasuwanni inda tallafin kayan aiki na dogon lokaci yana da mahimmanci.

V. ISA vs PCI da sauran Ka'idodin Fadada Ramin

Kamar yadda kayan aikin kwamfuta suka samo asali, iyakokin abubuwan Farashin ISA ya haifar da sababbin, sauri, kuma mafi sassauƙa fadada musaya kamar PCI, Bus na gida na VESA, AGP, kuma a ƙarshe PCI Express (PCIe). Fahimtar yadda ISA yana kwatanta da PCI da sauran ma'aunai suna taimakawa bayyana ficewar sa a hankali a cikin na'ura mai kwakwalwa.

Kwatancen Ayyuka da Gudu

Nau'in Bus	Fadin Bayanai	Gudun Na Musamman	Tallafin toshe-da-Play
DAYA (8/16-bit)	8-16 guda	~8MB/s	A'a
TSOHO	32 bits	Har zuwa 132 MB/s	A'a
PCI	32/64 bit	133 MB/s	Ee
PCIe	Serial (x1-x16)	Har zuwa kewayon GB/s	Ee

na DAYA layi daya bas gine, manual Tsarin IRQ/DMA, kuma ƙananan bandwidth ya zama ƙugiya don abubuwan da ke cikin sauri. Da bambanci, PCI gabatar Toshe-da-Play, mafi girma kayan aiki, kuma sarrafa bas, kyale na'urori suyi sadarwa ba tare da CPU ba.

Me yasa PCI ya maye gurbin ISA

Mafi girman gudu kuma hanyar data fadi

AGP aka ɓullo da musamman ga katunan bidiyo
PCI Express yanzu ya mamaye da jerin gine-ginen gine-gine da hanyoyi masu daidaitawa

Duk da kasancewar rashin aiki a kwamfutar tafi-da-gidanka na zamani, ISA ya rage a amfani ciki PCs masana'antu, inda dogon rayuwa goyon bayan rayuwa, deterministic hali, kuma hardware kwanciyar hankali ana fifita su akan aiki. PCI da PCIe na iya mamaye kasuwannin aiki, amma don gado da aikace-aikacen da aka haɗa, Sauƙin ISA ya ci gaba da bayar da aminci mara misaltuwa a cikin wuraren sarrafawa.

MU. Ramin ISA a cikin Masana'antu da Aikace-aikacen Haɗe-haɗe

Yayin da ramukan ISA sun ɓace daga kwamfutocin mabukaci na zamani, sun kasance abin mamaki dacewa a masana'antu saka tsarin kwamfuta. A cikin waɗannan mahalli, ba a ba da fifiko kan saurin aiki ko yanke-wuri ba, amma a kunne dogara na dogon lokaci, deterministic iko, kuma hardware kwanciyar hankali- yankunan da ISA fadada katunan ci gaba da bunƙasa.

Me yasa Har yanzu Ana Amfani da ISA a Masana'antu

Haɗin kayan aikin gado: Yawancin injunan masana'anta da benci na gwaji har yanzu sun dogara ISA I/O katunan ci gaba shekaru da yawa da suka wuce.
Dogayen rayuwar samfur: An gina tsarin masana'antu don ɗorewa 10-20+ shekaru, sau da yawa yana buƙatar goyon baya akai-akai don tsofaffin matakan hardware.
Stable lantarki dubawa: DAYA 5V sigina, gyarawa Ayyukan IRQ/DMA, da sauƙin lokacin bas yana tabbatar da daidaiton aiki a cikin mahalli masu hayaniya.
Abubuwan da aka haɗa na al'ada: Wasu kwamfutoci guda ɗaya (SBCs) kuma jirgin baya ci gaba da haɗa ramukan ISA don tallafawa kayan aikin gado na gado.

Aikace-aikacen Masana'antu gama gari:

Yankin Aikace-aikace	Misali Na'urori
Factory Automation	Digital I/O, motsi iko katunan ISA
Gwaji & Aunawa	Katunan sayan bayanai (DAQ).
Tsarin Sufuri	Hanyoyin sadarwa da sarrafawa
Kayan Aikin Lafiya	Na'urorin sa ido tare da tallafin gado
Tsarin Soja/Aerospace	Masu sarrafa tushen tushen ISA masu kauri

A cikin waɗannan sassan, farashin haɓakawa ko sake fasalin kayan aiki don tallafawa sabbin motocin bas kamar PCIe iya zama prohibitively high. Saboda, masana'antu motherboards kuma kwamfutoci tare da tallafin ISA har yanzu dillalai ne ke kera su.

VII. Yadda za a Gano Ramin ISA akan Motherboard?

Gane wani Farashin ISA na a motherboard yana da mahimmanci ga masu fasaha da ke aiki da su tsarin gado, PCs masana'antu, ko retro computing ayyukan. Kodayake ba a samun su a cikin kayan masarufi na zamani, ramukan ISA har yanzu suna bayyana a ciki na musamman motherboards gina domin saka ko aikace-aikacen sarrafa kansa.

Halayen Jiki na Ramin ISA

Ramin ISA yana da sauƙin ganewa da zarar kun san abin da zaku nema:

Tsawon: Yawanci fiye da PCI ko PCIe ramummuka
Launi: Yawancin lokaci baki ko duhu launin ruwan kasa
Nau'in Haɗawa:
- 8-bit DAYA ramummuka suna da 62 wuraren tuntuɓar juna
- 16-bit DAYA ramummuka kara kara da 98 pin, sau da yawa yana bayyana azaman ramin kashi biyu

The 16-bit ISA ya bayyana azaman doguwar haɗi tare da a yanki mai daraja zuwa bayan hukumar. Wasu motherboards na iya tallafawa duka PCI da ISA, don haka za ku ga cakuda nau'ikan ramuka.

Matsayin Ramin da Layout

Sau da yawa kusa da gefen ƙasa na AT ko ATX motherboards
A fili ya rabu da farar PCI ko guntun PCIe ramummuka

X. Madadin Zamani da Adafta

Kamar yadda fasaha ta ci gaba, Farashin ISA An fi mayar da su phased fita a cikin ni'imar mafi inganci da sauri musaya kamar PCI, PCIe, kuma USB. Koyaya, masana'antu da yawa har yanzu suna dogaro da su legacy ISA cards don aikace-aikace masu mahimmancin manufa. Don cike wannan gibin, da yawa madadin zamani da ISA-to-PCI ko adaftar USB sun fito, suna ba da damar tsofaffin kayan aikin su yi aiki a cikin sababbin tsarin.

Madadin ISA a Tsarin Zamani:

Katin PCI/PCIe: Bada mafi girman bandwidth, toshe-da-wasa goyon baya, kuma mafi dacewa da tsarin aiki na zamani.
I/O na tushen USB: Sauya katunan ISA don siyan bayanai, sadarwar serial, da ayyukan I/O na dijital.
Kwamfutocin da aka haɗa tare da tallafin ISA: Wasu kwamfutocin masana'antu har yanzu sun haɗa da ramukan ISA don haɗin kai na gado.

XII. Kammalawa: Shin Har yanzu ISA tana da mahimmanci a yau?

Ko da yake Farashin ISA ya daɗe da yin ritaya daga PC ɗin masu amfani, yana ci gaba da taka muhimmiyar rawa a ciki legacy computing, tsarin kula da masana'antu, kuma shigar aikace-aikace. A wuraren da hardware daidaito, deterministic yi, kuma dogon samfurin rayuwa cycles kwayoyin halitta fiye da sauri, ISA ya kasance abin dogaro mai dogaro.

Inda har yanzu ISA ke da mahimmanci:

Kwamfutocin masana'antu gami da rackmount pc, 4U rackmount pc, 2U rackmount pc, 1 ku pcamfani a masana'anta sarrafa kansa, sarrafa motsi, kuma samun bayanai
Magunguna da tsarin sararin samaniya inda takaddun shaida ke kulle a cikin kayan aikin gado
Retro kwamfuta al'ummomin kiyaye tsarin tarihi

A taƙaice, yayin da ISA ba ta sake fitar da sabbin abubuwa na yau da kullun ba, tana riƙe darajar a cikin niche sassa ina kwanciyar hankali kuma dacewa ga gado ba za a iya sasantawa ba. Fahimtar amfani mai dorewa na ISA yana taimaka wa injiniyoyi da manajojin IT su yanke shawara mai fa'ida yayin tallafawa ko ƙaura tsofaffin tsarin.
