HIFI-PCBAFunction Description

1. Core board. Sarudza iyo core board zvinoenderana nezvinodiwa zveprojekiti.
2. VBAT magetsi ekupa interface uye simba switch.
3. Muedzo wazvino. Paunenge uchiyedza chip VBAT ikozvino, zvinodikanwa kubatanidza multimeter mukati
   series. kune iyi interface, Pazvisina kufanira kuyera ikozvino, kavha pfupi inofanira kuva
   yakaiswa.
4. USB interface. a) Senge yekurodha interface yeiyo chip; b) Paunenge uchigadzirisa USB
   basa rechip, rinogona kushandiswa se USB mudziyo interface, senge USB flash disk
   Interface.
5. SD/TF kadhi interface. Kumberi kune SD kadhi interface, uye kumashure kune TF kadhi interface.
6. PWR kiyi. Yakabatanidzwa kune chip PWR pini, inogona kuita mabasa akadai
   PP/PWK.VOL+/NEXT, VOL -/PREV, nezvimwewo maererano nekugadzirisa software.
7. ADKEY kiyi. Batanidza kune chip GPIOx, inova ADC CHx. Maererano nesoftware
   gadziriro, mabasa akadai sePP, VOL+/NEXT, VOL -/PREV anogona kuitika.
8. Pabhodhi MIC kusarudzwa. Sarudza iyo MICL kana MICR nzira yechip kuburikidza nepini. Cherechedza
   kuti haasi ese mamodheru anotsigira MICL uye MICR.
9. Onboard PA inobuda Paunenge uchigadzirisa basa remutauri, unogona kuriridza kunze
   onboard PA kuti uteerere kune debugging maitiro.
10. AUX audio source yekupinda. Ekunze odhiyo masosi anogona kuiswa kuburikidza neiyi interface uye
    inotumirwa kune chip kuti igadziriswe.
11. Audio inobuda interface. DAC-VBF inoenderana nekuruboshwe interface, uye DAC-CAP
    inoenderana neiyo interface.
12. Digital kuratidza skrini. Ratidza nguva, vhoriyamu, chimiro,

Hifi Algorithm Tsananguro

Kushandisa raibhurari yeNatureDSP seraibhurari ine chekuita nehunyanzvi hwesainzi komputa pa
Candence HIF14 chikuva, chakanyorwa pachikuva chedu uye chakawedzerwa kune
project.kusanganisira algorithm modules senge fft, fir, iir, math, matinv, uye mufananidzo. Izvi
anowanzo shandiswa sainzi komputa mabasa anogadziridzwa mukati uchishandisa manualHIF14
mirairo, iyo inoshanda zvakanyanya uye inobatsira zvikuru mukuvandudza simba remakomputa.
