Hiina jaoks on SSD kontrollerite masstoodang sama oluline kui NAND-flashi ja DRAM m\u00e4lu kodumaine tootmine. Riigis on juba alustatud piiratud tootmist 32-kihilisest 3D NAND-ist ja DDR4 kiipidest. Kuidas on asjad aga kontrolleritega?<\/p>\n

\"K\u00f5ik<\/p>\n

Vastavalt veebilehe <\/a>EXPreview<\/a><\/noindex>, arendavad Hiinas SSD kontrollerite kallal umbes k\u00fcmme ettev\u00f5tet. K\u00f5ik nad kasutavad mingit ARM arhitektuuri v\u00f5i tuumade kombinatsiooni. Kuid \u00fchele ettev\u00f5ttele \u00f5nnestus \u00fcllatada: paar p\u00e4eva tagasi esitles riiklik arendaja Hiinas kontrollerit, mis p\u00f5hineb esimese Hiina mikrop\u00f5hja arhitektuuril Godson.<\/p>\n

Godson arhitektuur v\u00f5i tuumad on olnud aluseks laialdaselt tuntud Loongson protsessoritele. Godson arhitektuur p\u00f5hineb MIPS-i k\u00e4sklustel ja on SSD kontrollerite jaoks sama hea nagu ARM arhitektuur. Godson IP p\u00f5hjal l\u00f5i Hiina ettev\u00f5te Guokewei. See on GK2302 lahendus, millel on SATA 6 Gbit\/s liides ja t\u00f6\u00f6kiirus kuni 500 MBytes\/s.<\/p>\n

Ettev\u00f5tte teatel on GK2302 kontroller IP Godson 15% tootlikum kui eelmine arendus ARM tuumadel (GK2301) ja tarbib 6,5% v\u00e4hem energiat. GK2302 kohta ei ole praegu rohkem teavet. Infoks, GK2301 toetab nelja m\u00e4lu kanalit koos LDPC vigade parandusega ja v\u00f5imaldab luua SSD-sid mahuga kuni 4 Tbit (kuni 32 NAND MLC\/TLC\/QLC kiipi). Toetatud liidesed - ONFI 3.0\/Toggle 2.0, samuti kr\u00fcpteerimine SM2\/3\/4 (rahvuslik standard) ja SHA-256\/AES-256. Midagi sarnast on oodata uue kontrolleri puhul.<\/p>\n

M\u00f5ned s\u00f5nad ettev\u00f5tte Guokewei kohta. See loodi 2008. aastal, kuigi tuli aktsiaturule alles 2017. aastal. Ettev\u00f5te spetsialiseerub kiipide arendamisele TV-receiverite, andmesalvestuss\u00fcsteemide, sensorite ja IoT-seadmete kontrollerite jaoks. 2018. aastal oli Guokewei k\u00e4ive umbes 57,68 miljonit dollarit. Samal ajal saab ettev\u00f5te Hiina valitsuse fondidelt toetusi, mis v\u00f5imaldavad tal edendada oma tegevust, muretsemata kasumlikkuse p\u00e4rast.<\/p>\n
