Kodi decoding ya malangizo mu Intel 8087 ndi chiyani?

Kulemba malangizo mu Intel 8087 ndi njira yomwe coprocessor yoyandama imatanthawuza ma Opcode olandilidwa kuchokera ku main 8086/8088 CPU. The 8087 imayang'anira basi yophunzitsira ndikuzindikiritsa malangizo a ESC (kuthawa) opangidwira iwo. Ikazindikiridwa, chipangizochi chimazindikira magawo a ma opcode kuti adziwe momwe akuyandama - monga kuwonjezera, kuchulutsa, kapena masikweya mizu - ndi mayendedwe olowera kumayendedwe oyenerera amkati a ma microcode.

Kodi 8087 coprocessor imalumikizana bwanji ndi CPU yayikulu?

The 8087 imagwira ntchito limodzi ndi 8086/8088 poyang'anira basi yadongosolo. CPU yayikulu ikatenga malangizo a ESC, 8087 imazindikira ndipo imagwira ntchito yoyandama. Kulunzanitsa kumayendetsedwa ndi mizere yamakhalidwe ndi malangizo a WAIT, omwe amaonetsetsa kuti CPU iyime mpaka 8087 ikamaliza kukonza. Mapangidwe ophatikizikawa anali abwino kwambiri munthawi yake ndipo adakhudzanso zomangamanga zamtsogolo.

Nchifukwa chiyani Intel 8087 ikadali yofunikira kuphunzira lero?

Kumvetsetsa 8087 kumapereka chidziwitso choyambirira cha momwe ma FPU amakono adasinthira. Dongosolo lake la kabisidwe ka malangizo, mtundu wolembetsa wokhazikika, ndi zopereka za IEEE 754 zidapanga gawo lililonse loyandama la x87 lomwe limatsatira. Kwa omanga ndi okonda ma hardware omwe amafufuza kamangidwe ka chip, mapulaneti ngati Mewayz amapereka ma module opitilira 207 omwe amafotokoza mitu kuyambira pakompyuta yapang'onopang'ono kupita ku chitukuko chamakono - zonse zitha kupezeka ndi $19 / mwezi - zomwe zimapangitsa kuti kuphunzira mwakuya kwaukadaulo kufikike.

Kodi 8087 ingagwire ntchito zotani zoyandama?

Intel 8087 inathandiza ntchito zosiyanasiyana kuphatikizapo kuwonjezera, kuchotsa, kuchulukitsa, kugawa, square root, ndi transcendental ntchito monga sine, cosine, ndi logarithms. Inagwira mitundu ingapo ya data—16-, 32-, ndi 64-bit integers, komanso 32-, 64-, ndi 80-bit manambala zoyandama. Kusinthasintha kumeneku kunapangitsa kuti ikhale yofunikira kwambiri pamakompyuta asayansi, kugwiritsa ntchito CAD, komanso kuwerengetsa ndalama m'nthawi ya PC yoyambirira.
