Kushumekiwe & DSP-TMS320C6746EZWTD4

I-DSPiwukucubungula isignali yedijithali futhi i-chip ye-DSP iyi-chip engasebenzisa ubuchwepheshe bokucubungula isignali yedijithali.I-DSP chip iyi-microprocessor esheshayo futhi enamandla ehlukile ngokuthi ingakwazi ukucubungula ulwazi ngokushesha.Ama-chips e-DSP anesakhiwo sangaphakathi se-Harvard esihlukanisa uhlelo nedatha, futhi abe neziphindaphindi zezingxenyekazi zekhompuyutha ezikhethekile ezingasetshenziswa ukuqalisa ngokushesha ama-algorithms ahlukahlukene okucubungula isignali yedijithali.Kumongo wenkathi yanamuhla yedijithali, i-DSP isiphenduke ithuluzi eliyisisekelo emkhakheni wezokuxhumana, amakhompuyutha, ama-electronics abathengi, njll. Ukuzalwa kwama-chips e-DSP isidingo sehora.Kusukela ngawo-1960, ngokuthuthuka okusheshayo kwamakhompiyutha kanye nobuchwepheshe bolwazi, ubuchwepheshe bokucubungula isignali yedijithali bazalwa futhi buye bathuthukiswa ngokushesha.Ku-chip ye-DSP ngaphambi kokuvela kokucubungula isignali yedijithali kungathembela kuphela kuma-microprocessors ukuthi aqedele.Kodwa-ke, ngenxa yejubane eliphansi lokucubungula lama-microprocessors alisheshi ngokwanele ukuhlangabezana nezidingo zesikhathi sangempela zesivinini esikhulu senani elikhulayo lolwazi.Ngakho-ke, ukusetshenziswa kokucutshungulwa kwesignali okusheshayo nangempumelelo sekuphenduke isidingo esiphuthumayo somphakathi.Ngawo-1970, isisekelo setiyori ne-algorithmic sama-chips e-DSP sase sikhulile.Kodwa-ke, i-DSP yayisebhukwini lokufunda kuphela, ngisho nohlelo oluthuthukisiwe lwe-DSP lwakhiwe izingxenye ezihlukene, izindawo ezisetshenziswayo zilinganiselwe emkhakheni wezempi, we-aerospace.Ngo-1978, i-AMI yakhipha i-chip S2811 yokuqala ye-DSP ye-monolithic emhlabeni, kodwa asikho isiphindaphinda sehadiwe esidingekayo kuma-chips e-DSP yesimanje;Ngo-1979, i-Intel Corporation yakhipha idivayisi ehlelekayo yezentengiselwano i-2920 iyi-chip ye-DSP.Ngo-1979, i-Intel Corporation of America yakhipha idivayisi yayo ehlelekayo yezentengiselwano i-2920, ingqophamlando enkulu yama-chips e-DSP, kodwa yayingenaso isiphindaphinda sehadiwe;ngo-1980, I-NEC Corporation yaseJapane yakhulula i-MPD7720 yayo, i-chip yokuqala ye-DSP yokuhweba ene-multiplier yehadiwe, futhi ngaleyo ndlela ibhekwa njengedivayisi yokuqala ye-DSP ye-monolithic.

Ngo-1982 umhlaba wazalwa isizukulwane sokuqala se-DSP chip TMS32010 kanye nochungechunge lwayo.Le divayisi ye-DSP esebenzisa ubuchwepheshe benqubo ye-Micron ye-NMOS, nakuba ukusetshenziswa kwamandla nosayizi kukhudlwana kancane, kodwa isivinini sekhompyutha sishesha izikhathi ezingamashumi kune-microprocessor.Ukwethulwa kwe-chip ye-DSP kuyingqopha-mlando, kuphawula isistimu yohlelo lwe-DSP ukusuka kumasistimu amakhulu ukuya ekwenzeni okuncane kwesinyathelo esikhulu esiya phambili.Maphakathi nawo-80s, ngokuvela kwe-CMOS inqubo ye-chip ye-DSP, amandla ayo okugcina kanye nesivinini sekhompiyutha aphindaphindekile, abe yisisekelo sokucutshungulwa kwezwi, ubuchwepheshe bokucubungula ihadiwe yezithombe.ngasekupheleni kweminyaka yama-80s, isizukulwane sesithathu sama-chips e-DSP.Ukwanda okwengeziwe kwejubane lekhompiyutha, ububanzi bohlelo lwayo lwanda kancane kancane emkhakheni wezokuxhumana, amakhompyutha;Ukuthuthukiswa kwe-DSP yama-90s kuyashesha kakhulu, ukuvela kwesizukulwane sesine nesesihlanu sama-chips e-DSP.Isizukulwane sesihlanu uma siqhathaniswa nesizukulwane sesine sokuhlanganiswa kwesistimu ephakeme, ama-DSP cores kanye nezingxenye ze-peripheral ezihlanganiswe ku-chip eyodwa.Ngemva kokungena ekhulwini lama-21, kwavela isizukulwane sesithupha se-DSP chips.Isizukulwane sesithupha sama-chips ekusebenzeni kokuchotshozwa okuphelele kwesizukulwane sesihlanu sama-chips, ngenkathi kusekelwe ezinhlosweni zebhizinisi ezihlukene sakha amagatsha amaningi omuntu siqu, futhi saqala ukukhula kancane kancane ezindaweni ezintsha.
