Come segnalano i nostri colleghi del sito AnandTech<\/a><\/noindex>, uno dei primi sviluppatori al mondo di SoC con architettura RISC-V open source, la societ\u00e0 SiFive<\/a><\/noindex> ha acquisito un pacchetto di propriet\u00e0 intellettuale sotto forma di blocchi IP per interfacce USB 2.0 e USB 3.x. L'accordo \u00e8 stato stipulato con la societ\u00e0 Innovative Logic, specialista nello sviluppo di blocchi licenziabili pronti per l'integrazione. In precedenza, Innovative Logic era gi\u00e0 stata notata<\/a><\/noindex> per le sue interessanti proposte di licenza gratuita per blocchi IP USB 3.0. L'accordo con SiFive rappresenta il culmine di tali esperimenti. In futuro, la propriet\u00e0 precedente di Innovative Logic continuer\u00e0 a vivere come parte integrante di piattaforme di progettazione SoC gratuite e commerciali basate sull'architettura RISC-V. All'azienda Huawei piacer\u00e0 certamente, se dovesse sentirsi costretta<\/a><\/noindex> a confrontarsi con ARM e x86.<\/p>\n

\"L'architettura<\/p>\n

Prima dell'acquisto dei blocchi IP di Innovative Logic, l'azienda SiFive era costretta a licenziare blocchi con interfacce USB da sviluppatori terzi, il che limitava, tra l'altro, le opportunit\u00e0 di licenziamento gratuito delle piattaforme per lo sviluppo di soluzioni su RISC-V. Pertanto, l'interesse per RISC-V diminuiva. L'accordo con Innovative Logic consentir\u00e0 di dotare la piattaforma delle interfacce pi\u00f9 avanzate, incluso USB 3.x Type-C, lo sviluppo del quale \u00e8 stato completato finora solo da alcune aziende nel mondo.<\/p>\n

\"L'architettura<\/p>\n

Insieme alla propriet\u00e0 intellettuale dell'azienda SiFive, passer\u00e0 il team di sviluppatori di Innovative Logic, situato a Bangalore, India. All'interno di SiFive, gli ex specialisti di Innovative Logic continueranno a sviluppare blocchi IP con interfacce USB. I dettagli dell'accordo non sono stati divulgati. Inoltre, non \u00e8 stato specificato per quali processi tecnologici sono stati creati i blocchi trasferiti nel contratto. \u00c8 noto solo che sono adatti per l'integrazione in SoC con produzione secondo \"processi tecnologici migliorati\". Non \u00e8 disponibile ulteriore informazione.<\/p>\n
