AMD CTO inotaura Chiplet: Iyo nguva ye photoelectric co-sealing iri kuuya

AMD chip kambani vakuru vakati remangwana AMD processors anogona kunge akashongedzerwa nemadomasi-chaiwo accelerators, uye kunyangwe mamwe maaccelerator anogadzirwa nevechitatu mapato.

Mutevedzeri weMutungamiriri Mukuru Sam Naffziger akataura ne AMD Chief Technology Officer Mark Papermaster muvhidhiyo yakaburitswa neChitatu, achisimbisa kukosha kwediki chip standardization.

"Domain-specific accelerators, ndiyo nzira yakanakisa yekuwana kuita kwakanyanya padhora pa watt.Naizvozvo, zvakafanira chose kuti zvifambire mberi.Iwe haugone kugadzira zvigadzirwa zvenzvimbo yega yega, saka chatinogona kuita kuve nediki chip ecosystem - chaizvo raibhurari, "Naffziger akatsanangura.

Aitaura nezve Universal Chiplet Interconnect Express (UCIe), chiyero chakavhurika cheChiplet kutaurirana chave chiripo kubva pakusikwa kwayo mukutanga kwe2022. Yakahwina rutsigiro rwakapararira kubva kune makuru eindasitiri vatambi vakaita se AMD, Arm, Intel uye Nvidia, zvakare. semamwe akawanda madiki ma brand.

Kubva pakatanga chizvarwa chekutanga cheRyzen neEpyc processors muna 2017, AMD yanga iri pamberi pediki chip architecture.Kubva ipapo, raibhurari yeImba yeZen yemachipisi madiki yakakura kuti isanganise akawanda compute, I/O, uye mapikicha emifananidzo, achibatanidza nekuaisa muvatengi vayo uye data center processors.

Muenzaniso weiyi nzira unogona kuwanikwa mu AMD's Instinct MI300A APU, iyo yakatanga muna Zvita 2023, Yakatakurwa negumi nematatu ega machipisi (mana maI/O machipisi, matanhatu eGPU machipi, uye matatu CPU machipisi) uye masere HBM3 memory stacks.

Naffziger akataura kuti mune ramangwana, zviyero zvakaita seUCIe zvinogona kubvumira machipisi madiki akavakwa nevechitatu mapato kuwana nzira yavo mumapakeji e AMD.Akataura nezvesilicon photonic interconnect - tekinoroji inogona kurerutsa bandwidth mabhodhoro - seine mukana wekuunza wechitatu-bato madiki machipisi kune AMD zvigadzirwa.

Naffziger anotenda kuti pasina yakaderera-simba chip yekubatanidza, tekinoroji haigoneke.

"Chikonzero chaunosarudza optical yekubatanidza ndechekuti iwe unoda hombe bandwidth," anotsanangura kudaro.Saka unoda simba rakaderera pachidimbu kuti uite izvozvo, uye diki chip mupakeji ndiyo nzira yekuwana yakaderera simba interface. "Akawedzera kuti anofunga kuti shanduko yekubatanidza-packaging optics "iri kuuya."

Kuti izvozvo zviitike, akati wandei esilicon photonics ekutanga ari kutotangisa zvigadzirwa zvinogona kuita izvo chaizvo.Ayar Labs, semuenzaniso, yakagadzira UCIe inoenderana photonic chip iyo yakasanganiswa mune prototype graphics analytics accelerator Intel yakavakwa gore rapfuura.

Kunyangwe yechitatu-bato madiki machipisi (photonics kana mamwe matekinoroji) vachawana nzira yavo muzvigadzirwa zve AMD zvinoramba zvichionekwa.Sezvatakambotaura, kumisikidzwa ingori imwe yematambudziko mazhinji anoda kukundwa kubvumidza heterogeneous akawanda-chip chips.Isu takabvunza AMD kune rumwe ruzivo nezve diki chip zano ravo uye tichakuzivisa iwe kana isu tikagamuchira chero mhinduro.

AMD yakambopa machipisi ayo madiki kune anokwikwidza chipmaker.Intel's Kaby Lake-G chikamu, chakaunzwa muna 2017, inoshandisa Chipzilla's 8th-chizvarwa musimboti pamwe ne AMD's RX Vega Gpus.Chikamu chichangobva kuitika paTopton's NAS board.
