IBM tshaj tawm qhov kev tshawb pom ntawm Power processor architecture

IBM tuam txhab tshaj tawm ntawm kev ua kom lub zog qhia teeb tsa architecture (ISA) qhib. IBM twb tau tsim lub koom haum OpenPOWER hauv xyoo 2013, muab kev tso cai rau POWER cov cuab yeej kev txawj ntse thiab kev nkag mus rau tag nrho cov lus qhia tshwj xeeb. Nyob rau tib lub sijhawm, cov nyiaj tau txais txiaj ntsig txuas ntxiv tau sau kom tau txais daim ntawv tso cai los tsim cov chips. Txij no mus, tsim koj tus kheej cov kev hloov kho ntawm cov chips raws li Lub Hwj Chim kev qhia teeb tsa architecture yuav dhau los ua pej xeem thiab tsis tas yuav muaj nuj nqis. Qhov no suav nrog txoj cai siv tag nrho IBM patents ntsig txog Lub Hwj Chim Dawb, thiab kev tswj xyuas qhov project raug xa mus rau zej zog, uas tam sim no
yuav koom nrog cov txheej txheem txiav txim siab.

Lub koom haum saib xyuas kev txhim kho, OpenPOWER Foundation, yuav txhais nyob rau hauv lub tis ntawm Linux Foundation, uas yuav tsim ib qho kev ywj pheej platform rau ntxiv kev sib koom ua ke ntawm lub zog architecture, tsis tau khi rau ib tug tshwj xeeb chaw tsim tshuaj paus. Mus rau OpenPOWER consortium twb koom ntau tshaj 350 tuam txhab uas muag. Ntau tshaj 3 lab kab ntawm cov cai rau lub cev firmware, specifications thiab circuits tsim nyog los tsim Power-compatible chips tau muab qhia rau cov zej zog.

Ntxiv rau kev ua cov lus qhia teeb tsa cov khoom siv Open Hardware, IBM kuj tau pab txhawb rau zej zog qee cov thev naus laus zis uas siv hauv Power9 chips, suav nrog kev siv software (softcore) ntawm POWER ISA, nrog rau cov qauv siv los tsim kev sib txuas- raws li extensions OpenCAPI (Qhib Coherent Accelerator Processor Interface) thiab OMI (Qhib Memory Interface). Cov kev siv software muab tso cai rau koj simulate kev ua haujlwm ntawm cov khoom siv siv siv Xilinx FPGA.

OpenCAPI thev naus laus zis yuav ua rau nws muaj peev xwm ua tiav qhov kev ua tau zoo tshaj plaws thiab tshem tawm cov fwj thaum txhim kho kev sib cuam tshuam ntawm cov txheej txheem txheej txheem thiab cov khoom siv sib xyaw ua ke, xws li GPUs, ASICs, ntau yam khoom siv accelerators, network chips thiab chaw cia khoom. OMI yuav ua kom lub zog dhau ntawm cov tswj hwm nco thiab txo qhov tshwm sim latencies. Piv txwv li, ua tsaug rau cov kev ntxiv no raws li Lub Hwj Chim, nws yuav muaj peev xwm tsim cov chips tshwj xeeb uas tau tsim los rau kev daws teeb meem ntawm kev txawj ntse txawj ntse thiab cov ntaub ntawv ua haujlwm siab hauv kev nco.

Piv rau cov uas twb muaj qhib architectures lawm NROOG и RISC V, Lub Hwjchim architecture feem ntau yog qhov txaus nyiam vim nws tau npaj rau kev tsim cov tshuab server niaj hnub, kev lag luam platforms thiab pawg. Piv txwv li, hauv kev sib koom tes ntawm IBM thiab NVIDIA thiab Mellanox, ob lub ntiaj teb cov pawg loj tshaj plaws tau tsim tawm raws li Lub Hwj Chim architecture, ua thawj coj. kev ntsuam xyuas Sab saum toj 500 supercomputer.
