Yini i-DSP
I-DSP (I-Digital Signal Processing) ibhekisela ekusetshenzisweni kwamakhompuyutha noma okokusebenza okukhethekile okucutshungulwa ukuze kuqoqwe, kuguqulwe, kuhlungwe, kulinganiswe, kuthuthukiswe, kucindezele, kuhlonzwe namanye amasiginali ngendlela yedijithali ukuze kutholwe ifomu lesiginali elihlangabezana nezidingo zabantu (i-microprocessor eshumekiwe). Kusukela ngeminyaka yawo-1960, ngokuthuthuka ngokushesha kobuchwepheshe bekhompyutha nolwazi, ubuchwepheshe be-DSP bavela futhi bathuthuka ngokushesha. Emashumini amabili eminyaka adlule, ukucubungula isignali yedijithali kuye kwasetshenziswa kabanzi kwezokuxhumana nakweminye imikhakha.
Izinzuzo zobuchwepheshe be-DSP:
- Ukunemba okuphezulu
- Umsebenzi ophezulu
- Ukwethembeka okuphezulu
- Ukuphindaphinda kokuhlukaniswa kwesikhathi
Izici zobuchwepheshe be-DSP:
1. Usekelo lwemisebenzi yokuphindaphinda okujulile
2. Ukwakheka kwenkumbulo
3. Amaluphu aphezulu ayiziro
4. Fixed-point computing
5. Imodi yokukhuluma ekhethekile
6. Ukubikezelwa kwesikhathi sokubulawa
7. Isethi yemiyalo ye-DSP egxilile
8. Izidingo zamathuluzi okuthuthukisa
Isicelo:
I-DSP isetshenziswa ikakhulukazi ezindaweni zesignali yomsindo, ukucubungula inkulumo, i-RADAR, i-seismology, umsindo, i-SONAR, ukubonwa kwezwi, nezinye izimpawu zezezimali. Isibonelo, i-Digital Signal Processing isetshenziselwa ukucindezela inkulumo kumaselula, kanye nokudluliswa kwenkulumo kumaselula.
Ku-In Vehicle Infotainment, iphrosesa yesiginali yedijithali i-DSP ihlinzeka ngokuyinhloko ngemisindo ethile, njengetiyetha, i-jazz, njll., kanti abanye bangathola futhi umsakazo we-high-definition (HD) kanye nomsakazo wesathelayithi ukuze bathole injabulo enkulu yomsindo nokubukwayo. Iphrosesa yesignali yedijithali i-DSP ithuthukisa ukusebenza nokusebenziseka kwezinhlelo ze-infotainment ezisemotweni, ithuthukisa ikhwalithi yomsindo nevidiyo, inikeze ukuguquguquka okwengeziwe nemijikelezo yokuklama esheshayo.
