Goldmont Tsim

Mar 14, 2019

Goldmont yog tus thib cim ntawm kev txiav txim siab uas tsis muaj zog Atom microarchitect tsim los rau theem pib cov duab thiab cov computers. Goldmont yog ua rau ntawm 14 nm manufacturing process thiab txhawb nqa txog plaub cores rau cov neeg siv khoom. Nws suav nrog Intel Gen9 graphics architecture nkag tau nrog Skylake.


Lub Goldmont microarchitecture ua rau kev vam meej ntawm Silvermont lub tsev vajtse, thiab ua kom muaj cov nram qab no:


Ib qho tawm ntawm kev txiav txim tiav cav nrog 3-dav hlau superscalar pipeline. Tshwjxeeb:

Lub decoder yuav txiav txim siab 3 cov lus qhia ib hlis twg.

Tus microcode sequencer tuaj yeem xa 3 qhov rooj rau ib lub voj voog mus rau qhov chaw tshwj xeeb.

Retirement txhawb zog siab 3 ntawm ib lub voj voog.

Kev ua haujlwm hauv qhov kev txiav txim siab uas yog kev sib tw ua ke ntawm cov kav dej los ntawm daim ntawv qhia decoder.

Ntau qhov kev txiav txim tiav qhov rais thiab cov pob taws uas ua rau kom tawm qhov tob hauv kev txiav tawm ntawm cov zauv, FP / SIMD, thiab cov kev qhia nco.

Tag nrho tawm ntawm kev txiav txim siab tiav thiab disambiguation. Goldmont microarchitecture tuaj yeem ua ib qho khoom thiab ib lub khw ntawm ib lub voj voog (piv rau ib lub pob los yog ib lub khw rau ib lub voj voog hauv Silvermont microarchitecture). Lub cim xeeb ntawm txoj kev nco kuj muaj xws li qib thib ob TLB li nrog 512 nkag rau 4KB nplooj ntawv.

Thaj chaw ua tiav rau hauv Goldmont microarchitecture muab peb lub raj xa dej thiab tuaj yeem ua rau txog peb yam yooj yim rau hauv cov haujlwm ALU kev khiav haujlwm ntawm ib ntu.

SIMD integer thiab floating-point cov lus qhia hauv lub 128-ntsis dav cav. Cov lus qhia thiab latency ntawm ntau cov lus qhia tau zoo tuaj, xws li PSHUFB nrog 1-zaug ntawm kev sib tw (piv rau 5 cycles rau Silvermont micarchitecture) thiab ntau lwm yam kev qhia SIMD nrog ob npaug ntawm cov ntaub ntawv.

Los ntawm cov lus qhia thiab latency ntawm cov lus qhia rau accelerating encryption / decryption (AES) thiab muaj tsawg dua ntawm multiplication (PCLMULQDQ) tau zoo tuaj yeem hauv Goldmont microarchitecture.

Lub Goldmont microarchitecture qhia cov lus qhia tshiab nrog kho vajtse ceev ceev hashing algorithm, SHA1 thiab SHA256.

Lub Goldmont microarchitecture kuj ntxiv kev txhawb rau kev qhia RDSEED rau cov cim naj npawb ntawm cov rooj sib tham uas pom NIST SP800-90C txuj.

PAUSE kev qhia latency yog qhov ua kom zoo dua kom pab tau zoo zog.
