DSPyog cov teeb liab ua tiav thiab DSP nti yog cov nti uas tuaj yeem siv cov teeb liab ua cov thev naus laus zis.DSP nti yog qhov ceev thiab muaj zog microprocessor uas yog qhov tshwj xeeb uas nws tuaj yeem ua cov ntaub ntawv tam sim ntawd.DSP chips muaj cov qauv Harvard sab hauv uas cais cov kev pab cuam thiab cov ntaub ntawv, thiab muaj cov khoom siv tshwj xeeb uas tuaj yeem siv los ua kom sai sai rau kev siv ntau yam teeb liab ua cov txheej txheem.Nyob rau hauv cov ntsiab lus ntawm niaj hnub digital era, DSP tau dhau los ua cov cuab yeej siv hauv kev sib txuas lus, khoos phis tawj, khoom siv hluav taws xob, thiab lwm yam. Lub hnub yug ntawm DSP chips yog qhov xav tau ntawm lub sijhawm.Txij li thaum xyoo 1960, nrog rau kev loj hlob sai ntawm cov khoos phis tawj thiab cov ntaub ntawv thev naus laus zis, digital teeb liab ua tshuab tau yug los thiab tau tsim sai heev.Hauv DSP nti ua ntej qhov tshwm sim ntawm cov teeb liab ua tiav tsuas yog tso siab rau microprocessors kom tiav.Txawm li cas los xij, vim qhov kev ua haujlwm qis dua ntawm microprocessors tsis nrawm txaus kom ua tau raws li qhov xav tau ntawm lub sijhawm ceev ntawm cov ntaub ntawv ntau ntxiv.Yog li ntawd, daim ntawv thov ntawm kev ua haujlwm sai thiab muaj txiaj ntsig zoo tau dhau los ua qhov kev xav tau ntawm kev sib raug zoo.Hauv xyoo 1970, qhov theoretical thiab algorithmic foundation ntawm DSP chips tau loj hlob.Txawm li cas los xij, DSP tsuas yog nyob rau hauv phau ntawv kawm xwb, txawm tias DSP tau tsim los yog tsim los ntawm cov khoom sib cais, nws cov chaw siv tsuas yog txwv rau tub rog, aerospace sector.1978, AMI tau tso tawm lub ntiaj teb thawj monolithic DSP nti S2811, tab sis tsis muaj cov khoom siv sib npaug tsim nyog rau niaj hnub DSP chips;Xyoo 1979, Intel Corporation tau tso tawm cov khoom lag luam programmable 2920 yog DSP nti.Xyoo 1979, Intel Corporation of America tau tso tawm nws cov khoom lag luam programmable 2920, qhov tseem ceeb tshaj plaws rau DSP chips, tab sis nws tseem tsis tau muaj cov khoom siv ntau ntxiv;Xyoo 1980, NEC Corporation ntawm Nyij Pooj tau tshaj tawm nws MPD7720, thawj qhov kev lag luam DSP nti nrog cov khoom siv sib npaug, thiab yog li suav hais tias yog thawj cov khoom siv monolithic DSP.

Xyoo 1982 lub ntiaj teb tau yug los thawj tiam ntawm DSP nti TMS32010 thiab nws cov koob.Cov cuab yeej DSP no siv cov txheej txheem micron NMOS thev naus laus zis, txawm hais tias lub zog siv hluav taws xob thiab qhov loj me me me me, tab sis cov kev suav ceev yog kaum lub sij hawm sai dua li microprocessor.Kev taw qhia ntawm DSP nti yog qhov tseem ceeb, nws cim DSP daim ntawv thov system los ntawm cov tshuab loj mus rau qhov me me ntawm cov kauj ruam tseem ceeb rau pem hauv ntej.Los ntawm nruab nrab-80s, nrog kev tshwm sim ntawm CMOS txheej txheem DSP nti, nws lub peev xwm khaws cia thiab kev suav ceev tau muab ntau ntxiv, ua lub hauv paus rau kev ua suab, duab kho vajtse ua tshuab.lig 80s, tiam thib peb ntawm DSP chips.Ntxiv rau kev nce hauv kev suav ceev, nws daim ntawv thov tau maj mam nthuav mus rau kev sib txuas lus, khoos phis tawj;90s DSP txoj kev loj hlob yog qhov ceev tshaj plaws, qhov tshwm sim ntawm plaub thiab thib tsib tiam ntawm DSP chips.Lub cim thib tsib piv nrog rau tiam thib plaub ntawm kev sib koom ua ke siab dua, DSP cores thiab cov khoom siv peripheral sib xyaw ua ke hauv ib nti.Tom qab nkag mus rau xyoo pua 21st, tiam thib rau ntawm DSP chips tau tshwm sim.Lub thib rau tiam ntawm chips nyob rau hauv kev ua tau zoo ntawm tag nrho cov crushing lub thib tsib tiam ntawm chips, thaum raws li nyob rau hauv txawv kev lag luam lub hom phiaj tsim ib tug xov tooj ntawm tus kheej ceg, thiab pib maj mam nthuav mus rau hauv cov cheeb tsam tshiab.
