Kwanan nan a karkashin rigar Linux Foundation an kirkiro wani sabon aiki, da CHIPS Alliance "Kayan Aiki gama gari don ma'amaloli, Masu sarrafawa da Tsarin aiki"(Kayan aiki gama gari don musaya, masu sarrafawa da tsarin aiki), aka yi niyya don inganta tsarin bude kayan aiki da haɓaka mafita dangane da tsarin gine-ginen RISC-V.
Waɗanda suka kafa wannan sabon aiki "CHIPS Alliance" su ne Google, SiFive, Western Digital da Esperanto Technologies. CHIPS Alliance an ƙaddara ta sanya kanta a matsayin tsaka tsaki da dandamali mai zaman kansa.
Menene haɗin gwiwa na CHIPS?
Wannan dandamali zai ba da dama ga masana'antun kayan aiki (Kayan aiki) na iya haɓaka ayyukansu tare don ƙirƙirar buɗewar aiwatar da CPU daga cikin-akwatin da kuma tsarin guntu guda (SoC) ta amfani da gine-ginen RISC-V.
RISC-V (wanda aka faɗi "Risk-Five") shine tsarin koyar da kayan aikin kyauta kyauta (ISA) bisa tsari mai kama da RISC. Ba kamar yawancin saitunan koyarwa ba, RISC-V's kyauta ne kuma buɗe kuma ana iya amfani dashi don kowane dalili.
Ba kowa damar zanawa, ƙera da siyar da kwakwalwan RISC-V da software. Duk da cewa ba shine farkon buɗe gine-ginen ISA ba, amma yana da mahimmanci saboda an tsara shi don ya zama mai amfani akan na'urori masu yawa.
Kodayake a halin yanzu kungiyar RISC-V Foundation tana aiki ne kawai da gine-gine daga umarnin da aka saita, amma baya aiki da takamaiman aiwatarwa.
Abin da ya sa aka haife wannan sabon tushe da aikin Allianceungiyar CHIPS shine shirya ingantaccen ƙirar buɗe guntu don na'urori masu hannu, tsarin kwamfuta, kayan masarufi da Intanet na abubuwa.

A matsayin gudummawar ku ta farko, wadanda suka kirkiro kawancen CHIPS suka gabatar da wadannan ayyukan don ci gaban hadin gwiwa.
