I SoC basati su questo nuovo nucleo sono principalmente destinati a sistemi server e workstation, ma potrebbero essere creati anche varianti semplificate per dispositivi mobili e incorporati.    <\/p>\n<p>\u00c8 stato dichiarato che, rispetto al P550, il nuovo nucleo del processore SiFive contiene 16 MB di cache L3 invece di 4 MB, pu\u00f2 integrare fino a 16 core in un unico chip invece di 4, opera a una frequenza di fino a 3,5 GHz invece di 2,4 GHz, supporta la memoria DDR5 e il bus PCI-Express 5.0. L'architettura complessiva del nuovo nucleo \u00e8 simile a quella del P550 e ha anche un carattere modulare, che consente di aggiungere negli SoC ulteriori blocchi con acceleratori specializzati o GPU. I dettagli verranno pubblicati a dicembre e i dati RTL pronti per esperimenti su FPGA saranno resi disponibili l'anno prossimo.        <\/p>\n<p>RISC-V offre un sistema di istruzioni aperto e flessibile, consentendo la creazione di SoC e microprocessori completamente aperti per una variet\u00e0 di applicazioni, senza richiedere royalties o imponendo restrizioni all'uso.
