Pour la Chine, la production de masse de contr\u00f4leurs pour la fabrication de SSD est tout aussi essentielle que l'organisation de la production nationale de m\u00e9moire NAND-flash et DRAM. Le pays a d\u00e9j\u00e0 lanc\u00e9 une production limit\u00e9e de NAND 3D \u00e0 32 couches et de puces DDR4. Qu'en est-il des contr\u00f4leurs ?<\/p>\n

\"Tout<\/p>\n

Selon le site <\/a>EXPreview<\/a><\/noindex>, en Chine, environ dix entreprises d\u00e9veloppent des contr\u00f4leurs pour SSD. Toutes utilisent une combinaison de c\u0153urs ou d'architectures ARM (ensembles d'instructions). Cependant, une entreprise a r\u00e9ussi \u00e0 \u00e9tonner : r\u00e9cemment, un d\u00e9veloppeur national chinois a pr\u00e9sent\u00e9 des contr\u00f4leurs bas\u00e9s sur la premi\u00e8re architecture de microprocesseur chinoise Godson.<\/p>\n

L'architecture ou les c\u0153urs Godson sont \u00e0 la base des processeurs Loongson, qui ont acquis une certaine renomm\u00e9e. L'architecture Godson repose sur des instructions MIPS et, en principe, elle est aussi performante pour les contr\u00f4leurs SSD que l'architecture ARM. Le contr\u00f4leur utilisant un IP Godson a \u00e9t\u00e9 cr\u00e9\u00e9 par la soci\u00e9t\u00e9 chinoise Guokewei. Il s'agit du GK2302 avec une interface SATA 6 Gbit\/s et une vitesse de fonctionnement allant jusqu'\u00e0 500 Mo\/s.<\/p>\n

Selon l'entreprise, le contr\u00f4leur GK2302 sur IP Godson est 15 % plus performant que la version pr\u00e9c\u00e9dente bas\u00e9e sur les c\u0153urs ARM (GK2301) et consomme 6,5 % d'\u00e9nergie en moins. Aucune autre information sur le GK2302 n'est disponible pour l'instant. Pour r\u00e9f\u00e9rence, le GK2301 prend en charge quatre canaux m\u00e9moire avec correction d'erreurs LDPC et permet de cr\u00e9er des SSD d'une capacit\u00e9 allant jusqu'\u00e0 4 To (jusqu'\u00e0 32 puces NAND MLC\/TLC\/QLC). Les interfaces prises en charge sont ONFI 3.0\/Toggle 2.0, ainsi que le chiffrement SM2\/3\/4 (norme nationale) et SHA-256\/AES-256. On peut s'attendre \u00e0 quelque chose de similaire de la part du nouveau contr\u00f4leur.<\/p>\n

\n\"Tout<\/p>\n

Quelques mots sur la soci\u00e9t\u00e9 Guokewei. Elle a \u00e9t\u00e9 fond\u00e9e en 2008, mais n'est entr\u00e9e en bourse qu'en 2017. L'entreprise se sp\u00e9cialise dans le d\u00e9veloppement de puces pour d\u00e9codeurs TV, syst\u00e8mes de stockage de donn\u00e9es, contr\u00f4leurs pour capteurs et objets connect\u00e9s \u00e0 Internet. En 2018, le chiffre d'affaires de Guokewei a atteint environ 57,68 millions de dollars. Par ailleurs, l'entreprise re\u00e7oit des subventions des fonds gouvernementaux chinois, ce qui lui permet de progresser sans se soucier de sa rentabilit\u00e9.<\/p>\n
