Chenjerera, ARM? Nyowani 64-bit Synopsys ARC cores ichaita katatu kuita

Vashoma vanhu vanoziva kuti iyo ARC processor architecture ndeimwe yeanowanzo architecture pamwe neARM, MIPS uye x86. Yakagadzirwa muma1980s, iyo ARC architecture inoshandiswa mumhando dzakasiyana dze microcontrollers kune dzakasiyana siyana dzepamusoro-tech zvigadzirwa, uye gore rega rega ingangoita. 1,5 bhiriyoni zvishandiso.

Munguva pfupi yapfuura, Synopsys Corporation yakazivisa chizvarwa chitsva che32- uye 64-bit ARC processor cores, iyo inovimbisa kuita katatu kana ichienzaniswa nevakatangira, uye zvakare ichabvumira kuvaka masisitimu-pa-chip ane gumi nemaviri cores. Nekudaro, iwo macores matsva achabvumira Synopsys kukwikwidza neARM munzvimbo dzinoverengeka.

"Zvishandiso zvakamisikidzwa senge SSD controllers kana network zviri kuramba zvichinetsa, zvinoda budiriro yakakura ine simba shoma uye saizi," akadaro John Koeter, mukuru mutevedzeri wemutungamiri wezvekushambadzira uye zano rezvivakwa paSynopsys. "Nekuburitswa kweiyo ARCv3 dhizaini uye iyo ARC HS5x uye HS6x cores, vanogadzira vachakwanisa kusangana nekuwedzera kuri kuita maSoCs avo nhasi uye mune ramangwana."

Nyowani Synopsys DesignWare ARC processor mhuri dzinosanganisira 32-bit cores HS56/HS57D/HS58 uye 64-bit kernels HS66/HS68. Iwo achangobva kuziviswa ma processors anonangidzirwa kune dzakasiyana siyana dzekushandisa senge solid-state drive (SSD) controllers, network controllers, mota autopilots, mota infotainment masisitimu nezvimwe zvakawanda. Tichifunga nezve kukura kwezvinodiwa zve RAM, 64-bit ARC HD6x ichakubvumidza iwe kugadzira masisitimu ane 4,5 PB yeDRAM, nepo zvishandiso zvinoenderana neARC HD5x zvichifanira kuzviganhurira kune mavhoriyamu madiki. Nekudaro, iwo chaiwo huwandu hweiyo RAM inotsigirwa inogona kunge ichitemerwa neiyo inoshanda sisitimu inoshandiswa, uye mabhenefiti anooneka e64-bit CPU anozotaurwa nepombi yakafara uye hombe rerejista faira.

Kana iri iyo DesignWare ARC HS5x uye DesignWare ARC HS6x zvivakwa, ivo vanotsigira iyo ARCv3 yekuraira set, iyo inogona kuwedzerwa ne APEX (ARC processor EXtensions) mirairo kana vamwe vevatengi vachida chimwe chinhu chakananga. Pamusoro pezvo, iyo ARC HS57D inoshongedzerwa neARCv3DSP dhijitari chiratidzo processor ine tsigiro yemirairo zana nemakumi mashanu. Iwo macores matsva ane kudzika kwepombi yematanho gumi, anogona kuita mirairo miviri pawachi kutenderera, uye zvakare akashongedzerwa ne150-bit inoyangarara point unit. Panguva imwecheteyo, shanduro dzepamusoro dzekernels dzinotsigira chikamu chechipiri cache (L10) inosvika 128 MB muhukuru.

Kutaura nezvekuita, Synopsys inoti 3 DMIPS paMHz muhuwandu hwekuverenga, pamwe ne5,1 CoreMark paMHz, iyo yakanaka kwazvo kune madiki cores ane mashoma mashandisiro emagetsi. Saka, 3 DMIPS paMHz yakakwirira kupfuura iyo yema processor ane simba Cortex-A55, nepo 5,1 CoreMark paMHz yakakwirira kupfuura chero ARM processor ye microcontrollers.

Imwe yeakakosha maficha eiyo nyowani DesignWare ARC HS5x uye DesignWare ARC HS6x mhuri kugona kugadzira system-on-chip (SoC) ine gumi nemaviri general chinangwa processor cores uye gumi nematanhatu accelerators. Imwe neimwe musimboti / accelerator mune yakadaro processor inomhanya nekumhanya kwayo wachi uye inoshandisa yayo yega subsystem kuti iwedzere kushanda kwesimba. Pamwe chete nemacores matsva, Synopsys inopawo on-chip cache coherent connection ine data data rate ye12 GB/s.

Iri rudzi rweSoC yakavakirwa pachivako cheArC hachina kunyanya kuwanda nhasi, asi uchifunga nezveanovimbisa ma processors e autopilot masisitimu, chengetedzo yedata, data flow control, akawanda-cores uye akasiyana marudzi eanomhanyisa achauya akanyatso. Iyo yekupedzisira ichagonesa Synopsys kukwikwidza neARM cores yenzvimbo muSoC yezvikumbiro izvi, izvo zvisati zvaitika. Saka, mugadziri weSSD Starblaze atove kufarira iyo DesignWare ARC HS5x uye DesignWare ARC HS6x cores.

"Vagadziri vakamisikidzwa vakakwenenzverwa vanoramba vachitarisana nematambudziko matsva mukuita basa repamusoro nehuwandu hwendangariro uye simba nekukura," akadaro Bruce Cheng, mukuru wesainzi kuStarblaze. "Iyo yakawanda-yakakosha kugona kweSynopsys 'itsva 32-bit ARC HS5x uye 64-bit HS6x processors ichaita kuti tikwanise kuwana mazinga matsva ekushanda kwemagetsi asina kupihwa nemamwe ma processor ari pamusika."

Synopsys ichatanga kupa ARC cores HS56, HS57D, HS58, HS66, HS68, pamwe neshanduro yavo yakawanda-processor HS56MP, HS57DMP, HS58MP, HS66MP, HS68MP, kutanga muchikamu chechitatu cha2020. Pamusoro pezvo, kambani ichapa iyo ARC MetaWare Development Toolkit yekugadzira machipisi zvichienderana neaya macores, pamwe nesimulator uye verifier kutarisa kushanda kweSoC isati yaitwa musilicon. Kana iri yerutsigiro kubva kune anoshanda masisitimu, iyo kernels nyowani ichaenderana nehuwandu hwekugovera kweLinux, Zephyr, pamwe nemhando dzakasiyana dzeanoshanda masisitimu.
