Cov neeg tsim khoom ntawm cov neeg siv khoom siv hluav taws xob portable ntsib ntau yam teeb meem. Lawv yuav tsum tsim kom muaj txiaj ntsig zoo thiab ntau lub suab daws teeb meem, thaum txuas lub sijhawm siv roj teeb. Ntawm qhov tod tes, cov chaw tsim khoom yuav tsum ua kom luv lub sijhawm txhim kho kom thiaj li tsim cov khoom tshiab hauv kev ua lag luam.

Nrog rau txoj kev loj hlob ntawm ultra-low zog siv codecs, txoj kev loj hlob ntawm embedded mini DSP thiab muaj zog daim ntawv qhia cov cuab yeej programming, manufacturers tam sim no muaj peev xwm teb rau cov complex xav tau kev pab. Rau cov tshuab ua kom nws tus kheej muab tso ua ke, thiab sib koom ua ke embedded analog I / O systems, ultra-low hwj chim thiab kev ua tau zoo ntawm cov khoom siv no tuaj yeem muab cov kev daws teeb meem qis rau lawv. Graphics programming ib puag ncig thiab nplua nuj software txuas cov tsev qiv ntawv tuaj yeem ua kom lub sijhawm ua tiav ntawm daim ntawv thov, kom nws tsawg dua qhov kev txhim kho ntawm txoj kev loj hlob nyob rau hauv cov kev pab cuam tsim ib puag ncig.

Rau kev ua haujlwm tsis tshua muaj hluav taws xob, ntau lub cim tshiab tsis muaj zog codec tuaj yeem ua haujlwm simulation thiab cov tub ntxhais digital hauv ib qho 1.5V rau 1.8V voltage.

Yog tias cov tub ntxhais digital ua haujlwm ntawm qhov hluav taws xob ntawm 1.26V, nws kuj tseem tuaj yeem txo qis kev siv hluav taws xob ntxiv. Ntau lub cuab yeej muaj lub zog qis, txawm li cas los xij, kev xaiv hloov pauv hloov hluav taws xob ntxiv tuaj yeem hloov kho lub zog raws li tus kheej kev teeb tsa thiab kev xaiv ua haujlwm siv hauv kev kaw thiab rov ua haujlwm, uas yuav pab cov tsim kom txo tau lub zog siv, thiab tom qab ntawd Optimization yog optimized raws li tus naj npawb ntawm cov channel, tso zis tsav tsheb, piv txwv, kev tawm tswv yim thiab cov khoom yuav tsum tau los ntawm cov tswv yim thiab cov zis ntawm lub teeb liab, thiab tsis muaj qhov sib txawv ntawm cov teeb meem xws li NR.

Raws li pom nyob rau hauv daim duab 1, lub hwj chim noj ntawm lub compiler tuaj yeem hloov kho los ntawm qhov kev ua haujlwm no, hais txog ntau hom kev tsim tawm suab (hu, ntawv xov xwm ringtone, suab sib txuas lus thiab suab paj nruag), sib txawv I / O configuration (lub xov tooj txawb xov tooj ua haujlwm) thiab cov teeb liab sib txawv ntawm cov kev xav tau (tso suab nrov thiab suab nrov sib txuas lus ib puag ncig) tuaj yeem ua tiav qhov kev ua tau zoo. Rau analog bypass hom kev ua haujlwm yam tsis hloov pauv, PLL tsis xav tau PLL, lossis chav kawm D tau tsav los ntawm AB hom headphone drive configuration, thiab kev tswj fais fab tuaj yeem muab cov kev xaiv ntxiv, thiab cov kev tswj xyuas no yog los ntawm I2C lossis SPI tsheb npav. Tswj.

Daim duab 1. SnR thiab kev txhim kho qhov hluav taws xob yuav ua rau muaj zog siv zog. Cov neeg siv tuaj yeem hloov kho lub zog hloov pauv mus rau lub sijhawm siv roj teeb uas tuaj yeem txuas ntxiv cov khoom siv suab nrov raws li lawv tus kheej daim ntawv thov thiab cov kev xav tau.

Lub zog ua haujlwm qis tuaj yeem ua rau ultra-low zog noj codewater nrog cov teeb liab ua haujlwm txo lub zog ntawm hluav taws xob / ntawv xov xwm mus rau 5MW, thiab ua kom lub zog noj ntawm 8kHz lossis 16kHz suab sib txuas lus hauv qab 7MW, thaum lub suab siab tshaj plaws 44.1KHz lub tso suab suab paj nruag playback zog txo qis dua 10MW. Ua ke nrog ultra-low zog cov ntaub ntawv hloov dua siab tshiab thiab tsis tshua muaj hluav taws xob siv teeb liab ua, cov txheej txheem kev tsim qauv ntawm inheid-muaj daim ntawv thov processor thiab compile mapping tuaj yeem siv lub zog txuag hluav taws xob rau tib lub nti.

Nyob rau hauv cov architectures, ultra-low zog siv codecs tuaj yeem ua qee yam lossis tag nrho cov suab ua haujlwm ntawm daim ntawv thov processor. Cov kab ke nrog cov zaus zaus chips lossis daim ntawv thov processor chips muaj analog tawm tswv yim thiab / lossis cov khoom tso tawm. Compiling lub encoder nrog lub teeb liab ua hauj lwm muab tus nqi qis thiab luv luv txoj kev loj hlob, uas muaj peev xwm integrate lwm yam hauj lwm los yog functions, tsis txhob re-program qhov kev pab cuam tsim los yog hloov lub tseem ceeb los yog daim ntawv thov processor, lwm Extending roj teeb siv sij hawm yog ib tug tshiab ultra-low zog noj coder nrog embedded mini DSP.

Cov cuab yeej siv no thiab lawv cov cuab yeej siv hluav taws xob muaj zog tuaj yeem muab cov kev daws teeb meem suab qis rau ntau lub suab ua haujlwm thiab kev sib txuas lus kev sib txuas lus. Ntawm lawv, lub zog noj ntawm lub tso suab ua si tuaj yeem qis li 2.4MW, uas yog ua tiav los ntawm kev siv cov duab software ib puag ncig, thiab ua kom yooj yim rau cov neeg tsim khoom tsim cov programming.

Kev sib tw hauv kev lag luam portable cov neeg siv khoom siv hluav taws xob yog qhov hnyav heev, thiab cov kev hloov pauv tau nrawm heev. Lub sijhawm sau npe sai thiab kev siv hluav taws xob tsawg tsawg ua rau cov neeg tsim khoom tsim cov txheej txheem thiab pab lawv tsim cov khoom tshwj xeeb. Ultra-low zog suab converter nrog DSP integrated thiab ib tug graphical software kev loj hlob ib puag ncig uas pab kom ceev programming yog qhov kev sib tw kom zoo dua.
