Photonic integrated circuits, kana optical machipisi, anogona kupa akawanda mabhenefiti pamusoro peavo emagetsi, senge kuderedzwa kwesimba rekushandisa uye kuderedzwa latency mukombuta. Ndosaka vaongorori vazhinji vachitenda kuti vanogona kunyatso shanda mukudzidza kwemichina uye nehunyanzvi hwekugadzira (AI) mabasa. Intel inoonawo tarisiro huru yekushandiswa kwesilicon photonics mune ino nzira. Chikwata chake chekutsvagisa mukati yakadzama matekiniki matsva anogona kuunza optical neural network nhanho padyo nezvokwadi.
Munguva pfupi yapfuura , yakatsaurirwa pakudzidza kwemichina, inotsanangura kuti tsvakurudzo mumunda we optical neural network yakatanga sei. Tsvakurudzo yakaitwa naDavid AB Miller naMichael Reck yakaratidza kuti rudzi rwe photonic circuit inozivikanwa seMach-Zehnder interferometer (MZI) inogona kugadzirwa kuti iite 2 Γ 2 matrix kuwanda kana yaiswa MZI pane katatu mesh yekuwedzera matrices makuru, munhu anogona. tora dunhu rinoshandisa matrix-vector kuwanda algorithm, kuverenga kwekutanga kunoshandiswa mukudzidza kwemichina.
Tsvagiridzo nyowani yeIntel yakanangana nezvinoitika kana kukanganisa kwakasiyana-siyana uko machipisi emeso anotapukirwa panguva yekugadzira (sezvo computational photonics iri analogi muchisikirwo) inokonzeresa mutsauko mukurongeka kwekombuta pakati pemachipi akasiyana emhando imwe chete. Kunyange zvazvo zvidzidzo zvakafanana zvakaitwa, munguva yakapfuura vainyanya kufunga nezve post-fabrication optimization kubvisa zvingangoitika zvisiri izvo. Asi nzira iyi ine hurombo scalability sezvo network inokura, zvichikonzera kuwedzera kwesimba rekombuta rinodiwa kumisikidza optical network. Panzvimbo pekugadzirwa kwemashure-yekugadzira, Intel akafunga machipisi ekudzidzira kamwe-kamwe isati yagadzirwa nekushandisa dhizaini-inoshivirira dhizaini. Iyo referensi optical neural network yakadzidziswa kamwe chete, mushure meiyo dzidziso paramita yakagovaniswa kune akati wandei akagadzirwa network zviitiko nemisiyano muzvikamu zvadzo.
Chikwata cheIntel chakafunga zvivakwa zviviri zvekuvaka masisitimu ehungwaru akavakirwa paMZI: GridNet uye FFTNet. GridNet inofungidzira inoisa MZIs mugridi, ukuwo FFTNet inoaisa mumashavishavi. Mushure mekudzidzisa zvese mukuenzanisa pakanyorwa nemaoko digit recognition deep learning benchmark task (MNIST), vatsvakurudzi vakaona kuti GridNet yakawana huchokwadi hwepamusoro kupfuura FFTNet (98% vs. 95%), asi FFTNet architecture "yakanyanya kusimba." Muchokwadi, kuita kweGridNet kwakadzikira pazasi pe50% nekuwedzera kweruzha rwekugadzira (kukanganisa kunoteedzera hurema hunogona kuitika mukugadzira optical chip), nepo FFTNet yakaramba yakangofanana.
Masayendisiti anoti tsvakiridzo yavo inoisa hwaro hwemaitiro ekudzidzira hungwaru nzira dzinogona kubvisa kudiwa kwekugadzirisa machipisi emagetsi mushure mekugadzirwa, kuchengetedza nguva yakakosha uye zviwanikwa.
"Sezvinoita chero maitiro ekugadzira, kumwe kukanganisa kuchaitika zvinoreva kuti pachave nemusiyano mudiki pakati pemachipi izvo zvinokanganisa kurongeka kwekuverenga," anonyora Casimir Wierzynski, mukuru director weIntel AI Product Group. "Kana optical neural entities ichizove chikamu chinoshanda cheAI yehardware ecosystem, ivo vanozofanira kuenda kumachipi akakura uye matekinoroji ekugadzira maindasitiri. Tsvagiridzo yedu inoratidza kuti kusarudza chivakwa chakakodzera kumberi kunogona kuwedzera zvakanyanya mukana wekuti machipisi achazowana kuita kwaunoda, kunyangwe pamberi pekugadzira misiyano. "
Panguva imwecheteyo iyo Intel iri kunyanya kuita tsvakiridzo, MIT PhD mumiriri Yichen Shen akatanga iyo Boston-based startup Lightelligence, iyo yakasimudza madhora gumi nemazana manomwe emamiriyoni emari yekufambisa uye. prototype optical chip yekudzidza muchina inokurumidza kakapetwa ka100 kupfuura yemazuva ano emagetsi machipisi uye zvakare inoderedza kushandiswa kwesimba nekuraira kwehukuru, iyo zvakare inoratidza zvakajeka vimbiso yephotonic tekinoroji.
