Microprocessor Cov hom phiaj tshwj xeeb

Mar 09, 2019

Ib tug microprocessor yog ib qho chaw ua haujlwm. Ob qho tshwjxeeb li tau ua raws li kev siv tshuab:


Ib lub teeb tsa digital teeb tsa (DSP) tshwj xeeb rau cov teeb meem ua.

Graphics ua cov chav nyob (GPUs) yog cov txheej txheem tsim rau cov sijhawm ua haujlwm ntawm 3D dluab. Tej zaum lawv yuav ua haujlwm tas li (raws li tau tshwm sim hauv xyoo 1990), los yog txhawb kev zov me nyuam. Nrog rau kev nce ntxiv ntawm GPGPU, GPUs yuav hloov mus rau cov qauv qhia dav dav dav dav (khiav compute shaders), thaum tuav kev pab kho rasterising, tiam sis tseem txawv ntawm CPUs hauv lawv cov optimized rau kev siv dhau latency, thiab tsis haum rau khiav daim ntawv thov lossis OS code.

Lwm cov koog tshwj xeeb muaj nyob rau kev yees duab thiab kev siv lub tshuab. (Saib: Ruaj Ntseg Ruaj Ntseg.)

Microcontrollers nruab ib lub microprocessor nrog peripheral li hauv nruab lub nruab. Cov no yuav muaj ntau hom lag luam sib txawv piv rau CPUs.

Systems hauv chip (SoCs) feem ntau muab sib txuas ua ke ib los yog ntau dua microprocessor los yog microcontroller cores.

32-ntsis processors muaj ntau lub logic dua ntu processors, 32-ntsis (thiab dav) processors tsim ntau cov suab paj nruag thiab muaj kev siv zog ntau dua li tus txheej txheem narrower.Reducing cov suab paj nruag ua rau txoj kev hloov dua ADC. Yog li, 8-los yog 16-bit processors yuav ua tau zoo tshaj 32-ntsis processors rau qhov system ntawm tus ntiv tes thiab microcontrollers uas yuav tsum tau siv hluav taws xob tsis tshua muaj hluav taws xob, los yog ib feem ntawm qhov sib xyaw nrog cov teeb meem sib xyaw nrog lub suab nrov-sensitive hauv-nti analog electronics xws li high-resolution analog rau digital converters, los yog ob leeg.


Cuaj kaum, kev lag luam tawm tau siv: khiav khiav 32-ntsis ntawm 8-ntsis nti yuav xaus siv zog ntau dua, raws li lub nti yuav tsum tau siv software nrog ntau cov lus qhia. Niaj hnub microprocessors mus rau hauv lub zog qis zog thaum ua tau, thiab muaj 8-ntsis nti khiav 32-ntsis cov lus teb yuav tsum nquag pauv ntau dua. Qhov no ua kom pom muaj txiaj ntsig ntawm software, hardware thiab siv cov qauv, thiab cov nqi.


Thaum tsim cov txheej txheem zoo sib xws, 8-ntsis microprocessors siv tsawg zog thaum khiav hauj lwm thiab tsawg zog thaum pw tsaug zog dua 32-ntsis microprocessors.


Txawm li cas los xij, ib tug 32-ntsis microprocessor tau siv tsawg zog tsawg tshaj li 8-ntsis microprocessor thaum daim ntawv thov yuav tsum muaj kev khiav dej num xws li floating-point lej uas siv ntau dua moos ntawm 8-ntsis microprocessor dua li ntawm 32-ntsis microprocessor, yog li 8-ntsis microprocessor siv ntau lub sijhawm hauv high-power kev khiav hauj lwm hom.
