ARM Mali-G77 GPU bụ 40% ngwa ngwa

Yana ọhụrụ processor isi Cortex-A77 ARM webatara ihe nrụpụta eserese emebere maka sistemụ mkpanaka otu mgbawa na-esote ọgbọ. Mali-G77, nke na-ekwesịghị inwe mgbagwoju anya na ihe ngosi ngosi ọhụrụ Mali-D77, akara mgbanwe site na ARM Bifrost architecture gaa Valhall.

ARM na-ekwupụta mmụba dị ukwuu na arụmọrụ eserese nke Mali-G77 - site na 40% ma e jiri ya tụnyere ọgbọ Mali-G76 dị ugbu a. Emere nke a ma site na usoro nka na ndozi ihe owuwu. Mali-G77 nwere ike inwe site na cores 7 ruo 16 (ịkwalite site na 1 ruo 32 ga-ekwe omume n'ọdịnihu), na nke ọ bụla n'ime ha fọrọ nke nta ka ọ bụrụ otu G76. N'ihi ya, smartphones dị elu ga-enwe otu ọnụ ọgụgụ nke cores GPU.

N'ime egwuregwu, ị nwere ike ịtụ anya nkwalite arụmọrụ n'etiti 20 na 40%, dabere n'ụdị ọrụ eserese eserese. Na-ekpe ikpe site na nsonaazụ nke ule Manhattan GFXBench na-ewu ewu, ịdị elu dị ukwuu nke GPU ọhụrụ karịa ọgbọ dị ugbu a ga-amanye Qualcomm na-emegide ya ichegbu onwe ya maka mmụba dị ukwuu na arụmọrụ eserese Adreno.

N'onwe ya, ihe owuwu Mali-G77 ọhụrụ na-ewepụta nkezi pasent 30 na arụmọrụ ike ma ọ bụ arụmọrụ, ARM kwuru. Ọgbọ nke abụọ nke ARM Valhall scalar architecture na-enye GPU ohere ime ntuziaka 16 kwa okirikiri n'otu oge na CU, ma e jiri ya tụnyere asatọ na Bifrost (Mali-G76). Ihe ọhụrụ ndị ọzọ na-agụnye nhazi usoro nkuzi siri ike na-akwalite ngwaike yana usoro nkuzi ọhụrụ ma na-ejigide ndakọrịta azụ na Bifrost. agbakwunyere nkwado maka usoro mkpakọ ARM AFBC1.3 na ihe ọhụrụ ndị ọzọ (FP16 render targets, layering rendering and vertex shader results) agbakwunyela.

Bifrost CU nwere igwe ogbugbu 3, nke ọ bụla n'ime ha gụnyere cache ntụziaka, ndekọ aha, na ngalaba njikwa Warp. Nkesa n'ofe igwe atọ a kwere ka e gbuo ntuziaka FMA 24 na 32-bit floating point precision (FP32). Na Valhall, CU nke ọ bụla nwere naanị otu injin ogbugbu, kewara n'etiti nkeji ọnụọgụ abụọ nwere ike ịhazi ntuziaka Warp 16 kwa elekere, na-ebute mkpokọta 32 FMA FP32 ntuziaka kwa CU. N'ihi mgbanwe ụkpụrụ ụlọ ndị a, Mali-G77 nwere ike ịrụ otu ụzọ n'ụzọ atọ ọzọ mgbakọ na mwepụ na mgbako yiri Mali-G76.

Na mgbakwunye, nke ọ bụla n'ime CU ndị a nwere ngọngọ ọrụ mgbakọ na mwepụ abụọ ọhụrụ. Igwe ngbanwe ọhụrụ (CVT) na-ejikwa akara integer, ezi uche, alaka na ntuziaka ntụgharị. Ngalaba Na-arụ Pụrụ Iche (SFU) na-eme ka ọnụọgụ ọnụọgụ ọnụọgụgụ, nkewa, mgbọrọgwụ square, logarithms na ọrụ integer ndị ọzọ dị mgbagwoju anya.

Ọkọlọtọ FMA ngọngọ nwere ọtụtụ ntọala na-akwado 16 FP32 ntuziaka kwa okirikiri, 32 maka FP16, ma ọ bụ 64 maka INT8 Dot Ngwaahịa. Nkwalite ndị a nwere ike inye nkwalite arụmọrụ ruru 60% na ngwa mmụta igwe.

Mgbanwe ọzọ dị mkpa na Mali-G77 bụ okpukpu abụọ nke arụmọrụ injin ederede, nke na-arụzi texels bilinear 4 kwa elekere ma e jiri ya tụnyere abụọ gara aga, 2 trilinear texels kwa elekere, na-eme ka FP16 na FP32 nzacha ngwa ngwa.

ARM emeela ọtụtụ mgbanwe ndị ọzọ, yana Mali-G77 na Valhall na-ekwe nkwa nkwalite arụmọrụ dị ukwuu maka ịrụ ọrụ egwuregwu na mmụta igwe. N'ụzọ dị mkpa, a na-edobe oriri ike na mpaghara mgbawa na ọkwa Bifrost, na-ekwe nkwa ngwaọrụ mkpanaka nwere arụmọrụ dị elu na-enweghị ịba ụba ike, ikpo ọkụ na nha chọrọ.
