DSPidhijitari chiratidzo chekugadzirisa uye DSP chip ndiyo chip inogona kushandisa dhijitari chiratidzo chekugadzirisa tekinoroji.DSP chip inokurumidza uye ine simba microprocessor iyo yakasarudzika pakuti inokwanisa kugadzirisa ruzivo ipapo ipapo.DSP machipisi ane yemukati Harvard chimiro chinopatsanura chirongwa uye data, uye ine yakakosha hardware yakawedzera iyo inogona kushandiswa kukurumidza kuita akasiyana edhijitari masaini ekugadzirisa algorithms.Mumamiriro ezvinhu emazuva ano edhijitari, DSP yakava chigadziro chekutanga mumunda wekutaurirana, makombiyuta, magetsi emagetsi, nezvimwewo. Kuberekwa kweDSP chips ndiko kudiwa kweawa.Kubva kuma1960, nekukurumidza kukurumidza kwemakomputa uye tekinoroji yeruzivo, tekinoroji yedhijitari yekugadzirisa tekinoroji yakazvarwa uye yakakurumidza kugadzirwa.Muiyo DSP chip kusati kwabuda kwedhijitari chiratidzo chekugadzirisa chinogona kungovimba nemamicroprocessors kuti apedze.Nekudaro, nekuda kweiyo yakaderera yekumhanyisa kumhanya kwe microprocessors haina kukurumidza zvakakwana kuti isangane neiyo yepamusoro-yekukurumidza-chaiyo-nguva zvinodiwa zvekuwedzera kwehuwandu hweruzivo.Naizvozvo, kushandiswa kwekukurumidza uye kunoshanda kwechiratidzo kugadzirisa kwave kuri kuwedzera kukurumidza kudiwa kwevanhu.Muma1970, iyo theoretical uye algorithmic hwaro hweDSP machipi hwakanga hwakura.Nekudaro, iyo DSP yaingove mubhuku, kunyangwe iyo yakagadziridzwa DSP sisitimu inoumbwa ne discrete zvikamu, nzvimbo dzekushandisa dzayo dzinogumira kumauto, chikamu chemuchadenga.1978, AMI yakaburitsa nyika yekutanga monolithic DSP chip S2811, asi hapana hardware yakawedzera inodiwa kune yazvino DSP machipisi;1979, Intel Corporation yakaburitsa inoshambadzira programmable mudziyo 2920 iri DSP chip.Muna 1979, Intel Corporation yeAmerica yakaburitsa chigadzirwa chayo chekutengesa 2920, chiitiko chikuru cheDSP chips, asi yakanga isati iine hardware multiplier;muna 1980, NEC Corporation yeJapan yakaburitsa MPD7720 yayo, yekutanga yekutengesa DSP chip ine Hardware multiplier, uye nekudaro inoonekwa seyokutanga monolithic DSP mudziyo.

Muna 1982 nyika yakazvarwa chizvarwa chekutanga cheDSP chip TMS32010 uye yakatevedzana.Ichi chishandiso cheDSP chinoshandisa micron process NMOS tekinoroji, kunyangwe mashandisirwo emagetsi uye saizi yakati kurei, asi kumhanya kwekombuta kuri kukurumidza makumi enguva kupfuura microprocessor.Kuunzwa kweiyo DSP chip chiitiko chakakosha, inocherekedza iyo DSP application system kubva kune mahombe masisitimu kusvika kuminiaturization yenhanho hombe kumberi.Pakazosvika pakati pe80s, nekubuda kweCMOS process DSP chip, kugona kwayo kuchengetedza uye kumhanya kwekombuta zvakapetwa, zvichiva hwaro hwekugadziriswa kwezwi, tekinoroji yekugadzira mifananidzo.kunonoka 80s, chizvarwa chechitatu cheDSP chips.Kuwedzera kuwedzera kwekumhanya kwekombuta, chiyero chekushandisa chayo chakawedzera zvishoma nezvishoma kusvika kumunda wekutaurirana, makomputa;90s DSP budiriro ndiyo inokurumidza, kubuda kwechizvarwa chechina nechishanu cheDSP chips.Chizvarwa chechishanu chichienzaniswa nechizvarwa chechina chepamusoro chekubatanidza system, iyo DSP cores uye peripheral components zvakabatanidzwa mune imwechete chip.Mushure mekupinda muzana remakore rechi21, chizvarwa chechitanhatu cheDSP chips chakabuda.Chizvarwa chechitanhatu chemachipisi mukuita kweiyo yakazara kupwanya chizvarwa chechishanu chemachipisi, nepo zvichibva pane zvakasiyana bhizinesi zvinangwa zvakagadzira akati wandei emapazi emunhu, uye akatanga kuwedzera zvishoma nezvishoma munzvimbo nyowani.
