HIFI-PCBAFunction Description

1. Core board. Xaiv lub core board raws li qhov project xav tau.
2. VBAT fais fab mov interface thiab fais fab hloov.
3. Kev sim tam sim no. Thaum kuaj nti VBAT tam sim no, nws yog ib qho tsim nyog los txuas lub multimeter hauv
   series. rau qhov interface no, Thaum nws tsis tsim nyog los ntsuas tam sim no, lub hau luv yuav tsum yog
   ntxig.
4. USB interface. a) Raws li rub tawm interface rau lub nti; b) Thaum debugging USB
   kev ua haujlwm ntawm cov nti, nws tuaj yeem siv los ua USB ntaus ntawv interface, xws li USB flash disk
   Interface.
5. SD/TF daim npav interface. Hauv ntej yog SD daim npav interface, thiab sab nraub qaum yog TF daim npav interface.
6. PWR key. Txuas nrog lub nti PWR tus pin, nws tuaj yeem ua tiav cov haujlwm xws li
   PP/PWK.VOL+/NEXT, VOL -/PREV, thiab lwm yam raws li software configuration.
7. ADKEY tus yuam sij. Txuas mus rau lub nti GPIOx, uas yog ADC CHx. Raws li software
   configuration, functions xws li PP, VOL +/NEXT, VOL -/PREV tuaj yeem paub.
8. Hauv kev xaiv MIC. Xaiv txoj kev MICL lossis MICR ntawm lub nti los ntawm tus pin. Nco tseg
   uas tsis yog txhua tus qauv txhawb MICL thiab MICR.
9. Onboard PA tso zis Thaum debugging tus hais lus muaj nuj nqi, koj tuaj yeem ua si nws tawm mus
   onboard PA kom mloog cov nyhuv debugging.
10. AUX audio source input. Cov ntaub ntawv suab sab nraud tuaj yeem nkag los ntawm qhov interface no thiab
    xa mus rau lub nti rau kev ua haujlwm.
11. Suab tso zis interface. DAC-VBF sib haum mus rau sab laug interface, thiab DAC-CAP
    sib raug rau txoj cai interface.
12. Digital zaub screen. Qhia sijhawm, ntim, xwm txheej,

Hifi Algorithm piav qhia

Siv NatureDSP lub tsev qiv ntawv ua ib lub tsev qiv ntawv muaj feem xyuam rau kev suav nrog kev tshawb fawb zoo ntawm
Candence HIF14 platform, nws tau muab tso ua ke ntawm peb lub platform thiab ntxiv rau lub
project.including algorithm modules xws li fft, fir, iir, lej, matinv, thiab duab. Cov no
Feem ntau siv scientific xam functions yog nyob rau hauv optimized siv manualHIF14
cov lus qhia, uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo hauv kev txhim kho kev suav lub zog.
