KuChina, kugadzirwa kwakawanda kwevanodzora kugadzirwa kweSSD kwakakosha sesangano rekugadzirwa kwemba kweNAND flash uye DRAM ndangariro. Kugadzirwa kushoma kwe32-layer 3D NAND uye DDR4 machipisi kwatotanga munyika. Zvakadini nevanodzora?
Maererano nenzvimbo , muChina, makambani angangoita gumi ari kugadzira vatongi veSSD. Vese vanoshandisa imwe musanganiswa wemacores kana ARM architecture (mirayiridzo seti). Asi imwe kambani yakakwanisa kushamisa: nguva pfupi yadarika mugadziri wenyika kubva kuChina akapa vatongi zvichibva pane yekutanga Chinese microprocessor architecture, Godson.
Iyo Godson architecture kana cores yakave hwaro hweLoongson processors akazozivikanwa zvakanyanya mukusavapo. Iyo Godson dhizaini inotsamira paMIPS mirairo uye iri, musimboti, haina kuipa kune vatongi veSDD kupfuura iyo ARM yekuvakisa. Iyo Godson IP controller yakagadzirwa neChinese kambani Guokewei. Aya ndiwo maGK2302 mhinduro ane SATA 6 Gb/s interface uye kumhanya kwekushanda kunosvika 500 MB/s.
Sekureva kwekambani, GK2302 controller paIP Godson ine 15% inobereka zvakanyanya kupfuura dhizaini yapfuura paArM cores (GK2301) uye inoshandisa 6,5% shoma simba. Iko hakuna rumwe ruzivo nezve GK2302 parizvino. Zvekureva, iyo GK2301 inotsigira mana ndangariro nzira neLDPC kukanganisa kukanganisa uye inobvumidza iwe kuti ugadzire maSSD ane huwandu hunosvika 4 TB (kusvika 32 NAND MLC/TLC/QLC machipi). Inotsigirwa interfaces: ONFI 3.0/Toggle 2.0, pamwe neSM2/3/4 (yenyika chiyero) uye SHA-256/AES-256 encryption. Chimwe chinhu chakafanana chinogona kutarisirwa kubva kumutongi mutsva.
Mashoko mashoma pamusoro pekambani yeGuokewei. Yakarongwa muna 2008, kunyangwe yakapinda mukutsinhana kwekuchengetedza muna 2017 chete. Iyo kambani inyanzvi mukugadzira machipisi e-set-yepamusoro mabhokisi, data rekuchengetedza masisitimu, ma controller ema sensors uye zvinhu zvakabatana neInternet. Muna 2018, Guokewei's turnover yaiva madhora mamiriyoni 57,68. Panguva imwecheteyo, kambani inogamuchira rubatsiro kubva kumari yehurumende yeChina, iyo inobvumira kuti ienderere mberi pasina hanya nekubudirira.
