Chii chinonzi DSP
DSP (Digital Signal Processing) inoreva kushandiswa kwemakomputa kana yakakosha kugadzirisa michina kuunganidza, kushandura, kusefa, fungidziro, kuwedzera, kudzvanya, kuona uye mamwe masaini mumhando yedhijitari kuti uwane fomu rechiratidzo rinosangana nezvido zvevanhu (embedded microprocessor). Kubva kuma1960, nekukurumidza kuvandudzwa kwekombuta neruzivo rwemichina, tekinoroji yeDSP yakabuda uye nekukasira. Mumakumi maviri emakore apfuura, dhijitari chiratidzo chekugadzirisa chave chichishandiswa zvakanyanya mukutaurirana uye mamwe minda.
Zvakanakira zveDSP tekinoroji:
- High kururama
- Basa repamusoro
- Kuvimbika kwakanyanya
- Nguva-kupatsanurwa multiplexing
Zvimiro zveDSP tekinoroji:
1. Tsigiro yemabasa ekuwanza
2. Chimiro chendangariro
3. Zero pamusoro zvishwe
4. Fixed-point computing
5. Special addressing mode
6. Kufanotaura kwenguva yekuuraya
7. Fixed-point DSP mirayiridzo yakagadzirirwa
8. Zvinodiwa zvekuvandudza maturusi
Chikumbiro:
DSP inoshandiswa zvakanyanya munzvimbo dzechiratidzo chekuteerera, kugadzirisa kutaura, RADAR, seismology, odhiyo, SONAR, kuzivikanwa kwezwi, uye mamwe masaini emari. Semuyenzaniso, Digital Signal Processing inoshandiswa pakutsikirira kwekutaura kwenharembozha, pamwe nekufambisa kutaura kwenharembozha.
Kune In Mota Infotainment, iyo dhijitari siginecha processor DSP inonyanya kupa chaiwo kurira kwemhanzi, senge theatre, jazz, nezvimwewo, uye vamwe vanogona zvakare kugamuchira yakakwirira-tsanangudzo (HD) redhiyo uye setiraiti redhiyo yekunakidzwa kwakanyanya-kuratidzwa. Iyo yedhijitari chiratidzo processor DSP inokwidziridza mashandiro uye kushandiswa kwemu-mota infotainment masisitimu, inovandudza odhiyo uye vhidhiyo mhando, ichipa kuwedzera kuchinjika uye nekukurumidza dhizaini kutenderera.
