Ifakwe kunye ne-DSP-TMS320C6746EZWTD4

I-DSPkukusetyenzwa komqondiso wedijithali kunye netshiphu ye-DSP yitshiphu enokuphumeza iteknoloji yokusetyenzwa komqondiso wedijithali.I-chip ye-DSP yi-microprocessor ekhawulezayo nenamandla ekhethekileyo kuba iyakwazi ukucwangcisa ulwazi ngoko nangoko.Iitshiphusi ze-DSP zinesakhiwo seHarvard sangaphakathi esahlula inkqubo kunye nedatha, kwaye zinezixhobo zokuphindaphinda ezikhethekileyo ezinokuthi zisetyenziswe ukuphumeza ngokukhawuleza iindlela ezahlukeneyo zokusetyenzwa komqondiso wedijithali.Kumxholo wexesha lanamhlanje ledijithali, i-DSP iye yaba sisixhobo esisisiseko kwintsimi yonxibelelwano, iikhomputha, i-electronics yabathengi, njl. Ukuzalwa kwee-chips ze-DSP yimfuneko yeyure.Ukususela ngo-1960, kunye nophuhliso olukhawulezayo lweekhompyutha kunye nobuchwepheshe bolwazi, iteknoloji yedijithali yokucwangcisa umqondiso yazalwa kwaye iye yaphuhliswa ngokukhawuleza.Kwi-chip ye-DSP ngaphambi kokuvela kwenkqubo yesignali yedijithali inokuxhomekeka kuphela kwi-microprocessors ukugqiba.Nangona kunjalo, ngenxa yesantya esisezantsi sokusebenza kwe-microprocessors ayikhawulezi ngokwaneleyo ukuhlangabezana neemfuno zexesha lokwenyani lesantya elandayo lolwazi.Ke ngoko, ukusetyenziswa kwenkqubo yophawu olukhawulezayo kunye nokusebenza kakuhle kuye kwaba yimfuno engxamisekileyo yentlalontle.Ngeminyaka yoo-1970, isiseko sethiyori kunye ne-algorithmic yeetshiphusi ze-DSP sele sikhulile.Nangona kunjalo, i-DSP yayikwincwadi yesikhokelo kuphela, nkqu inkqubo ye-DSP ephuhlisiwe yenziwe ngamacandelo ahlukeneyo, iindawo zayo zokusebenza zilinganiselwe kumkhosi, icandelo le-aerospace.Ngo-1978, i-AMI yakhulula i-monolithic DSP chips yokuqala yehlabathi ye-S2811, kodwa akukho siphindaphinda se-hardware esiyimfuneko kwiitshiphusi ze-DSP zanamhlanje;Ngo-1979, i-Intel Corporation yakhupha i-2920 isixhobo esicwangcisiweyo sorhwebo yi-chip ye-DSP.Ngo-1979, i-Intel Corporation yaseMelika yakhupha isixhobo sayo esicwangcisiweyo sorhwebo i-2920, isiganeko esibalulekileyo se-chips ze-DSP, kodwa ayizange ibe ne-multiplier ye-hardware;ngo 1980, NEC Corporation of Japan wakhulula MPD7720 yayo, itshiphu yokuqala yorhwebo DSP kunye multiplier hardware, yaye ngaloo ndlela ithathwa isixhobo yokuqala monolithic DSP.

Ngo-1982 ihlabathi lazalwa isizukulwana sokuqala se-DSP chip TMS32010 kunye nochungechunge lwayo.Esi sixhobo se-DSP sisebenzisa inkqubo ye-micron iteknoloji ye-NMOS, nangona ukusetyenziswa kwamandla kunye nobukhulu bukhulu kancinane, kodwa isantya se-computing singamashumi amaxesha ngokukhawuleza kune-microprocessor.Ukuqaliswa kwe-chip ye-DSP yinto ephawulekayo, iphawula inkqubo yesicelo se-DSP ukusuka kwiinkqubo ezinkulu ukuya kwi-miniaturization yenyathelo elikhulu eliya phambili.Phakathi kwe-80s, kunye nokuvela kwenkqubo ye-CMOS ye-chip ye-DSP, amandla ayo okugcina kunye nesantya se-computing yandisiwe, ibe sisiseko sokulungiswa kwezwi, iteknoloji yokucubungula i-hardware yemifanekiso.80s emva kwexesha, isizukulwana sesithathu chips DSP.Ukonyuka ngakumbi kwisantya sekhompyuter, umda wesicelo wanda ngokuthe ngcembe ukuya kwintsimi yonxibelelwano, iikhompyuter;Uphuhliso lwe-90s ye-DSP yeyona nto ikhawulezayo, ukuvela kwesizukulwana sesine nesesihlanu se-chips ze-DSP.Isizukulwana sesihlanu xa kuthelekiswa nesizukulwana sesine sokuhlanganiswa kwenkqubo ephezulu, i-DSP cores kunye ne-peripheral components ehlanganiswe kwi-chip enye.Emva kokungena kwinkulungwane yama-21, kwavela isizukulwana sesithandathu seetshiphusi ze-DSP.Isizukulwana sesithandathu chips kwintsebenzo yokutyumza ngokubanzi kwisizukulwana sesihlanu chips, ngelixa ngokusekelwe kwiinjongo zoshishino ezahlukeneyo uphuhlise inani lamasebe zobuqu, kwaye waqala ngokuthe ngcembe ukwandisa kwiindawo ezintsha.
