2024-08-13 16:29:49

Masiku ano kusinthika kwachangu Dziko loyendetsedwa ndi AI, kufunikira kowerengera mwachangu, kothandiza kwambiri kwapangitsa kuti mapurosesa apadera monga ma Neural Processing Unit (NPU). Mosiyana ndi chikhalidwe CPUs kapena GPUs, NPU idapangidwa kuti ifulumire mfundo yophunzirira makina, makamaka za maukonde azama neural yogwiritsidwa ntchito mu masomphenya apakompyuta, chilankhulo chachilengedwe kukonza,ndi kuzindikira mawu.

An NPU ndi mtundu wa AI accelerator yomwe imapereka magwiridwe antchito apamwamba, otsika-latency kukonza ntchito zomwe zimafunikira kuwerengera kofananira ndi ntchito za tensor. Mapurosesa awa tsopano akuphatikizidwa m'mapulatifomu osiyanasiyana-kuchokera mafoni ndi Zida za IoT ku machitidwe amagalimoto ndi m'mphepete kompyuta zomangamanga- kuthandizira pa chipangizo AI ndi kugwiritsa ntchito mphamvu zochepa.

Chifukwa chiyani ma NPU Afunika:

Kuchita bwino munthawi yeniyeni kwa ntchito za AI
Kugwiritsa ntchito mphamvu zochepa poyerekeza ndi mayankho a GPU
Kuchepetsa kudalira malingaliro amtambo, kukonza zinsinsi za data ndi latency
Scalability kwa zida zazing'ono ndi machitidwe ophatikizidwa

Kukwera kwa mbali AI ndi kuchuluka kwa Mapulogalamu oyendetsedwa ndi AI zipangitseni kuti mumvetsetse kuti NPU ndi chiyani komanso momwe imasiyana ndi magawo ena opangira. M'nkhaniyi, tikufufuza za zomangamanga, ntchito milandu, ndi kufunikira kwa njira za NPU muzinthu zambiri zamakompyuta anzeru.

Kodi NPU ndi chiyani? Chidule chaukadaulo

A Neural Processing Unit (NPU) ndi microprocessor yodzipereka yomwe idapangidwa kuti igwire Artificial Intelligence (AI) kuchuluka kwa ntchito, makamaka zomwe zikukhudza kuphunzira mozama ndi neural network inference. Mosiyana ndi cholinga chambiri CPUs kapena zojambulajambula GPUs, ma NPU amakonzedwa kuti azigwira ntchito zamasamu mphamvu makina ophunzirira makina, monga kuchulukitsa kwa matrix, convolutions,ndi tensor processing.

Makhalidwe a NPU:

Zolinga zopangidwira kutengera kwa AI, osati maphunziro
Amachita ntchito zofananira bwino
Zokometsedwa za low-latency, high-throughput katundu wolemetsa
Imagwira ntchito kwambiri kugwiritsa ntchito mphamvu zochepa kuposa GPUs

Pamene CPUs ndi abwino kwa sequential logic ndi GPUs kuchita bwino pa ntchito zamasewera ndi masewera, NPU zidapangidwa kuti zifulumizitse ntchito monga:

Kuzindikira kwa chinthu
