Zophatikizidwa ndi DSP-TMS320C6746EZWTD4

DSPndi makina opanga ma digito ndipo DSP chip ndi chipangizo chomwe chimatha kugwiritsa ntchito ukadaulo wa digito.Chip cha DSP ndi microprocessor yachangu komanso yamphamvu yomwe ili yapadera chifukwa imatha kukonza zambiri nthawi yomweyo.Tchipisi za DSP zili ndi mawonekedwe amkati a Harvard omwe amalekanitsa pulogalamu ndi data, ndipo amakhala ndi zochulukitsa zapadera zomwe zingagwiritsidwe ntchito kukhazikitsa ma algorithms osiyanasiyana opangira ma siginecha.Pankhani yamasiku ano a digito, DSP yakhala chida chofunikira kwambiri pazolumikizana, makompyuta, zamagetsi zamagetsi, ndi zina zambiri. Kubadwa kwa tchipisi ta DSP ndikofunikira pa ola.Kuyambira m'ma 1960, ndi chitukuko chofulumira cha makompyuta ndi zamakono zamakono, luso lamakono la digito linabadwa ndipo lapangidwa mofulumira.Mu Chip cha DSP kusanachitike kwa makina a digito kungadalire ma microprocessors kuti amalize.Komabe, chifukwa cha kutsika kwapang'onopang'ono kwa ma microprocessors sikuthamanga mokwanira kuti akwaniritse zofunikira zenizeni zenizeni za kuchuluka kwa chidziwitso.Chifukwa chake, kugwiritsa ntchito ma siginecha mwachangu komanso kothandiza kwambiri kwakhala chofunikira kwambiri pagulu.M'zaka za m'ma 1970, maziko amalingaliro ndi algorithmic a tchipisi a DSP anali atakhwima.Komabe, DSP idangokhala m'mabuku ophunzirira, ngakhale dongosolo la DSP lopangidwa limapangidwa ndi zigawo zingapo, madera ake ogwiritsira ntchito amangokhala ankhondo, gawo lazamlengalenga.1978, AMI anatulutsa dziko loyamba monolithic DSP Chip S2811, koma palibe multiplier hardware zofunika tchipisi DSP zamakono;1979, Intel Corporation inatulutsa chipangizo chogulitsira malonda 2920 ndi chipangizo cha DSP.Mu 1979, Intel Corporation of America inatulutsa chipangizo chake chogulitsira malonda 2920, chofunika kwambiri cha tchipisi cha DSP, komabe chinalibe chowonjezera cha hardware;mu 1980, NEC Corporation ya ku Japan inatulutsa MPD7720 yake, chipangizo choyamba cha DSP chamalonda chokhala ndi chochulukitsira cha hardware, motero chimatengedwa ngati chipangizo choyamba cha monolithic DSP.

Mu 1982 dziko linabadwa m'badwo woyamba wa DSP Chip TMS32010 ndi mndandanda wake.Chipangizo ichi cha DSP chogwiritsa ntchito ukadaulo wa Micron NMOS, ngakhale kugwiritsa ntchito mphamvu ndi kukula kuli kokulirapo pang'ono, koma liwiro la makompyuta ndi nthawi makumi khumi kuposa ma microprocessor.Kukhazikitsidwa kwa chipangizo cha DSP ndichinthu chofunikira kwambiri, chikuwonetsa dongosolo la DSP kuchokera ku machitidwe akuluakulu kupita ku miniaturization ya sitepe yayikulu patsogolo.Pofika pakati pa zaka za m'ma 80, ndi kutuluka kwa CMOS ndondomeko ya DSP chip, mphamvu zake zosungirako ndi liwiro la kompyuta zachulukitsidwa, kukhala maziko opangira mawu, teknoloji ya hardware processing.mochedwa 80s, m'badwo wachitatu wa DSP chips.Kuwonjezeka kwina kwa liwiro la makompyuta, kuchuluka kwake kwa ntchito kumawonjezeka pang'onopang'ono kumunda wa mauthenga, makompyuta;Kukula kwa 90s DSP ndikothamanga kwambiri, kutuluka kwa m'badwo wachinayi ndi wachisanu wa tchipisi ta DSP.M'badwo wachisanu poyerekeza ndi m'badwo wachinayi wophatikizira machitidwe apamwamba, ma cores a DSP ndi zida zotumphukira zophatikizidwa mu chip chimodzi.Pambuyo polowa m'zaka za zana la 21, m'badwo wachisanu ndi chimodzi wa tchipisi ta DSP udatulukira.M'badwo wachisanu ndi chimodzi wa tchipisi mu ntchito ya wonse kuphwanya m'badwo wachisanu wa tchipisi, pamene zochokera zolinga zosiyanasiyana malonda anayamba angapo payekha nthambi, ndipo anayamba kukula pang'onopang'ono m'madera atsopano.
