Cov teebmeem ntawm cov teebmeem ua tiav

Mar 11, 2019

DSP algorithms tej zaum yuav khiav ntawm cov qauv siv computer thiab digital cov teeb meem kev lag luam. DSP algorithms kuj tau siv rau kev ua vaj tse tsim ua vaj tse xws li daim ntawv thov kev sib xyuas (ASICs). Lwm cov technologies ntxiv rau cov teeb meem ntawm cov teeb meem muaj xws li ntau lub hom phiaj microprocessors, qhov chaw ua lag luam kom tiav (FPGAs), cov teeb liab ntawm digital (feem ntau rau cov ntawv muaj xws li kev tsav tsheb), thiab cov chaw khiav dej num.


Rau cov tshuab uas tsis muaj qhov yuav tsum tau ua kom raws sij hawm thiab cov ntaub ntawv teeb liab (cov tswv yim los yog tso tawm) muaj nyob rau hauv cov ntaub ntawv cov ntaub ntawv, kev ua haujlwm yuav tsum tau muab kev lag luam nrog rau lub tshuab computer. Qhov no yeej tseem zoo tsis txawv ntawm lwm cov ntaub ntawv ua, tsuas yog siv DSP kev ua lej (xws li FFT), thiab cov ntaub ntawv sampled yog feem ntau xav tias yuav tsum sib xyaw ua ke hauv lub sijhawm lossis chaw. Ib qho piv txwv ntawm cov ntaub ntawv xws li ua cov duab cov duab nrog software xws li Photoshop.


Thaum daim ntawv thov yuav tsum yog lub sijhawm tiag tiag, DSP feem ntau tau siv cov tshwjxeeb lossis cov haujlwm lossis microprocessors, qee zaus los siv ntau hom kev lag luam lossis ntau hom kev ua haujlwm. Cov no yuav ua tau cov ntaub ntawv siv cov ntsiab lus ntawm cov ntsiab lus ntawm cov ntsiab lus los yog floating point. Yuav siv ntau daim ntawv thov FPGAs. Rau cov ntawv thov lossis cov khoom ntim siab tshaj plaws, ASICs yuav raug tsim los siv rau daim ntawv thov.
