Neural network IP da nufin SoCs aiki maganganun hadaddun

Abubuwan albarkatu sun isa don tabbatar da muryar murya ta wuri, inda mai amfani ya kasance mita daga microphone. Masu taimakawa na gida mai sarrafa murya na murya da na infotainment na mota suna nufin aikace-aikace.

Me yasa zancen magana akan PCB?

"Abubuwan da ke tattare da cibiyar sadarwa ta hanyar sadarwa ta hanyar sadarwa ta hanyar sadarwa ta hanyar sadarwa ta hanyar sadarwa ne, maimakon a cikin girgije, saboda damuwa da latency, sirri da kuma samar da hanyoyin sadarwa," in ji Cadence.

Da ake kira HiFi 5, yana da sau biyu iya aiki mai jiwuwa da kuma sau hudu da hanyar sadarwa na Nural (NN) na farko HiFi 4 DSP.

"Manufarmu ita ce ta samar da wata babbar fasahar ƙamus a cikin gida wanda ke iya sarrafa harshe na halitta," in ji Gerard Andrews, darektan kasuwanci na kamfanin Cadence, ga Electronics Weekly. "Mun yi nazari akan hanyoyin sadarwa ta hanyar sadarwa ta hanyar budewa, kuma mun tsara HiFi 5 don gudanar da waɗannan nau'ukan sadarwa.

Tsarin abubuwa sun haɗa da:

• Bayanin kalma mai tsawo (VLIW) mai tsawo na tsawon lokaci yana iya samar da nauyin nau'i nau'i 128-bit a kowane zagaye
• DSP multiplier-accumulators:
  Taimako don 8 32x32bit MAC / sake zagayowar ko 16 16x16bit MAC / sake zagayowar
  Zaɓin zaɓi guda takwas masu mahimmanci na MAC ta hanyar zagaye
• Cibiyoyin sadarwa na cibiyar sadarwa na cibiyar sadarwa na Neural:
  32 16 × 8 MAC / zagaye ko 16 × 4 MAC / sake zagayowar
  Yanki mai haɓaka 16 mai mahimmanci ma'anar MAC ta hanyar zagaye

DSP MACs, a cewar Andrews, sun haɗa da, misali, goyon baya don saturation, yayin da ake amfani da MACs na ƙananan ƙwayoyin don ƙara yawan darajar mata ta hanyar matrix. "A cikin cibiyoyin sadarwa masu yawa, kun ƙaddara bayar da lokaci mai yawa na karuwa da ƙananan mata ta matrix," in ji shi, ya kara da cewa: zaɓin yawan MAC da za a haɗa, da kuma irin nau'ukan bayanai da tsayin daka don tallafawa, ya kasance bisa ga aiki tare da abokan ciniki na HiFi 4.

An kafa maths matattun ruwa don sharuɗɗa guda biyu - ƙayyadadden ƙaddamar da ƙananan murya don ƙaddamar da katako da kuma sakewa, da kuma rabin ƙayyadaddun ga wasu hanyoyin sadarwa. "Abinda yake ba da haske ya ba da sauri ga kasuwannin," In ji Andrews. "Alal misali, idan ka ci gaba da wani abu mai guba a MatLab, juya shi zuwa matsayin mai-tsafi yana da cin lokaci."

Yawancin masu tallafawa suna tallafawa sikelin 8 don "babban yunkuri ne don ƙididdigewa har zuwa samfurori 8bit don faɗar magana, wanda ba shi da kasuwanci da yawa a daidaito. Kuna ganin takardun da aka gabatar a inda mutane ke kokarin sauka zuwa 4bits, "In ji Andrews. "Muna fatan cewa mafi yawan algorithms za su yi amfani da 16x8bit multiplier: 16bits don bayanai daga microphone da 8bits ga ma'aunin nauyi."

Don wasu nauyin ma'auni, 4bit, 2bit da 1bit aiki yana samuwa da 8bit.

Ambiq Micro, mai samar da microcontrollers wanda aka gina a kan 'ƙananan ƙananan ƙwayar' silikoni matakai don ajiye ikon, shi ne abokin ciniki na farko HiFi 5.

"Don saduwa da kalubale mai wuya na kawo jigilar hanyoyin sadarwa ta hanyar sadarwar da ke da hanyar sadarwa ta hanyar yanar gizo, Ambiq Micro ya zaɓi ya zama na farko lasisin lasisin na Cadence ta HiFi 5 DSP", in ji Ambiq vp of marketing Haruna Grassian. "Shigar da HiFi 5 DSP zuwa Ambiq Micro ta hanyar ƙaddamar da ƙwaƙwalwar ƙarfin ikon Ambiq Micro don samar da na'urorin fasaha, ODMs da OEM don amfani da fasaha daga masu amfani da labarun jihohi kamar DSP Concepts da Sensory ta ƙara haɗin haɗin murya, umarni da iko, da tattaunawa ta hanyar HUKARI zuwa ƙwaƙwalwar ajiya, samfurorin hannu ba tare da bada kyauta ko rayuwar batir ba. "

Taimako ga dukiyar ilimi, akwai ɗakunan ɗakin karatu na ayyukan ɗakunan karatu wanda aka saba amfani dashi a cikin hanyoyin sadarwa na cibiyar sadarwa - musamman don maganganun magana. Wadannan ayyuka suna nufin haɗin kai a cikin shahararren masarufin tsarin koyarwa.

HiFi 5 yana jituwa tare da ɗakin ɗakunan kamfanoni na katunan sauti da murya na murya, da kuma kayan haɓakaccen kayan aiki na audio, waɗanda aka ƙaddara don ƙananan sutura na samfurin HiFi na kamfanin.
