Los SoC basados en el nuevo n\u00facleo est\u00e1n orientados principalmente a sistemas de servidores y estaciones de trabajo, aunque tambi\u00e9n es posible la creaci\u00f3n de versiones reducidas para dispositivos m\u00f3viles y embebidos.    <\/p>\n<p>Se ha declarado que, en comparaci\u00f3n con el P550, el nuevo n\u00facleo de procesador de SiFive contiene 16 MB de cach\u00e9 L3 en lugar de 4 MB, puede combinar hasta 16 n\u00facleos en un solo chip en lugar de 4, opera a una frecuencia de hasta 3.5 GHz en lugar de 2.4 GHz, admite memoria DDR5 y el bus PCI-Express 5.0. La arquitectura general del nuevo n\u00facleo es similar a la del P550 y tambi\u00e9n tiene un car\u00e1cter modular, que permite agregar bloques adicionales con aceleradores especializados o GPU al SoC. Se planea publicar m\u00e1s detalles en diciembre, y los datos RTL listos para experimentaci\u00f3n en FPGA se publicar\u00e1n el pr\u00f3ximo a\u00f1o.        <\/p>\n<p>RISC-V proporciona un sistema de instrucciones de m\u00e1quina abierto y flexible que permite crear SoC y microprocesadores totalmente abiertos para aplicaciones variadas, sin necesidad de regal\u00edas y sin imponer condiciones para su uso. Actualmente, sobre la base de la especificaci\u00f3n RISC-V, diversas empresas y comunidades est\u00e1n desarrollando 111 variantes de n\u00facleos de microprocesadores bajo distintas licencias libres (BSD, MIT, Apache 2.0), junto con 31 plataformas, 12 SoC y 12 productos listos.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=56013\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f SiFive, \u043e\u0441\u043d\u043e\u0432\u0430\u043d\u043d\u0430\u044f \u0441\u043e\u0437\u0434\u0430\u0442\u0435\u043b\u044f\u043c\u0438 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u044b \u043d\u0430\u0431\u043e\u0440\u0430 \u043a\u043e\u043c\u0430\u043d\u0434 RISC-V \u0438 \u0432 \u0441\u0432\u043e\u0451 \u0432\u0440\u0435\u043c\u044f \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u0438\u0432\u0448\u0430\u044f \u043f\u0435\u0440\u0432\u044b\u0439 \u043f\u0440\u043e\u0442\u043e\u0442\u0438\u043f \u043f\u0440\u043e\u0446\u0435\u0441\u0441\u043e\u0440\u0430 \u043d\u0430 \u0431\u0430\u0437\u0435 RISC-V, \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u0438\u043b\u0430 \u043d\u043e\u0432\u043e\u0435 RISC-V \u044f\u0434\u0440\u043e CPU \u0432 \u043b\u0438\u043d\u0435\u0439\u043a\u0435 SiFive Performance, \u043a\u043e\u0442\u043e\u0440\u043e\u0435 \u043d\u0430 50% \u0431\u044b\u0441\u0442\u0440\u0435\u0435 \u043f\u0440\u043e\u0448\u043b\u043e\u0433\u043e \u0442\u043e\u043f\u043e\u0432\u043e\u0433\u043e \u044f\u0434\u0440\u0430 P550 \u0438 \u043e\u043f\u0435\u0440\u0435\u0436\u0430\u0435\u0442 \u043f\u043e \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0438\u0442\u0435\u043b\u044c\u043d\u043e\u0441\u0442\u0438 ARM Cortex-A78, \u043d\u0430\u0438\u0431\u043e\u043b\u0435\u0435 \u043c\u043e\u0449\u043d\u044b\u0439 \u043f\u0440\u043e\u0446\u0435\u0441\u0441\u043e\u0440 \u043d\u0430 \u0431\u0430\u0437\u0435 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u044b ARM.
