F\u00f6r Kina \u00e4r massproduktion av kontroller f\u00f6r SSD-tillverkning lika viktigt som att organisera inhemsk produktion av NAND-flashminne och DRAM. I landet har begr\u00e4nsad produktion av 32-lagers 3D NAND och DDR4-chips redan startat. Hur ligger det d\u00e5 till med kontrollerna?<\/p>\n

\"Allt<\/p>\n

Enligt webbplatsen <\/a>EXPreview<\/a><\/noindex>, utvecklar cirka tio f\u00f6retag kontroller f\u00f6r SSD i Kina. Alla anv\u00e4nder n\u00e5gon kombination av k\u00e4rnor eller ARM-arkitekturer (instruktionsupps\u00e4ttningar). Men en f\u00f6retag har lyckats \u00f6verraska: nyligen presenterade en nationell utvecklare fr\u00e5n Kina kontroller baserade p\u00e5 den f\u00f6rsta kinesiska mikroprocessorkonstruktionen Godson.<\/p>\n

Godson-arkitekturen eller k\u00e4rnorna har blivit grunden f\u00f6r de popul\u00e4ra Loongson-processorerna. Godson-arkitekturen baseras p\u00e5 MIPS-instruktioner och \u00e4r i princip inte s\u00e4mre f\u00f6r SSD-kontroller \u00e4n ARM-arkitekturen. Kontrollen baserad p\u00e5 Godson-IP skapades av det kinesiska f\u00f6retaget Guokewei. Det h\u00e4r handlar om GK2302-l\u00f6sningen med SATA 6 Gbit\/s gr\u00e4nssnitt och en \u00f6verf\u00f6ringshastighet p\u00e5 upp till 500 MB\/s.<\/p>\n

Enligt f\u00f6retaget \u00e4r GK2302-kontrollern med IP Godson 15 % prestandastarkare \u00e4n den tidigare versionen baserad p\u00e5 ARM-k\u00e4rnor (GK2301) och drar 6,5 % mindre energi. Det finns f\u00f6r n\u00e4rvarande ingen ytterligare information om GK2302. F\u00f6r referens st\u00f6der GK2301 fyra minneskanaler med LDPC-felkorrigering och m\u00f6jligg\u00f6r skapandet av SSD:er med en kapacitet p\u00e5 upp till 4 TB (upp till 32 NAND MLC\/TLC\/QLC-chip). St\u00f6dda gr\u00e4nssnitt \u00e4r ONFI 3.0\/Toggle 2.0 samt kryptering SM2\/3\/4 (nationell standard) och SHA-256\/AES-256. N\u00e5got liknande kan f\u00f6rv\u00e4ntas av den nya kontrollern.<\/p>\n

\n\"Allt<\/p>\n

N\u00e5gra ord om Guokewei. F\u00f6retaget grundades 2008, men gick f\u00f6rst offentligt 2017. F\u00f6retaget specialiserar sig p\u00e5 utveckling av chips f\u00f6r TV-boxar, datalagringssystem, kontroller f\u00f6r sensorer och Internet-uppkopplade enheter. \u00c5r 2018 var Guokeweis oms\u00e4ttning cirka 57,68 miljoner dollar. Samtidigt f\u00e5r f\u00f6retaget bidrag fr\u00e5n de kinesiska statliga fonderna, vilket g\u00f6r att det kan forts\u00e4tta fram\u00e5t utan att t\u00e4nka p\u00e5 l\u00f6nsamhet.<\/p>\n
