Comme le rapportent nos coll\u00e8gues du site AnandTech<\/a><\/noindex>, l'une des premi\u00e8res entreprises au monde \u00e0 d\u00e9velopper des SoC sur l'architecture ouverte RISC-V, la soci\u00e9t\u00e9 SiFive<\/a><\/noindex> a acquis un lot de propri\u00e9t\u00e9 intellectuelle sous la forme de blocs IP pour les interfaces USB 2.0 et USB 3.x. La transaction a \u00e9t\u00e9 r\u00e9alis\u00e9e avec l'entreprise Innovative Logic, sp\u00e9cialis\u00e9e dans le d\u00e9veloppement de blocs licenciables pr\u00eats \u00e0 int\u00e9grer. Auparavant, Innovative Logic avait d\u00e9j\u00e0 \u00e9t\u00e9 remarqu\u00e9e<\/a><\/noindex> pour ses offres int\u00e9ressantes de licences d'essai gratuites pour les blocs IP USB 3.0. La transaction avec SiFive marque le point culminant de telles exp\u00e9rimentations. \u00c0 l'avenir, l'ancienne propri\u00e9t\u00e9 d'Innovative Logic continuera \u00e0 vivre comme une partie int\u00e9grante des plateformes gratuites et commerciales pour la conception de SoC sur l'architecture RISC-V. Cette perspective plaira certainement \u00e0 Huawei, si elle est finalement contrainte<\/a><\/noindex> face \u00e0 ARM et x86.<\/p>\n

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

Avant l'acquisition des blocs IP d'Innovative Logic, la soci\u00e9t\u00e9 SiFive devait licencier des blocs avec des interfaces USB aupr\u00e8s de d\u00e9veloppeurs tiers, ce qui, en particulier, limitait les possibilit\u00e9s de licences gratuites pour les plateformes de d\u00e9veloppement de solutions sur RISC-V. En cons\u00e9quence, l'int\u00e9r\u00eat pour RISC-V diminuait. La transaction avec Innovative Logic permettra de doter la plateforme des interfaces les plus avanc\u00e9es, y compris USB 3.x Type-C, dont le d\u00e9veloppement a \u00e9t\u00e9 achev\u00e9 pour seulement quelques entreprises dans le monde.<\/p>\n

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

Avec la propri\u00e9t\u00e9 intellectuelle de l'entreprise SiFive, l'\u00e9quipe de d\u00e9veloppeurs d'Innovative Logic, bas\u00e9e \u00e0 Bangalore, en Inde, rejoindra SiFive. Dans le cadre de SiFive, les anciens sp\u00e9cialistes d'Innovative Logic continueront de d\u00e9velopper des blocs IP avec des interfaces USB. Les d\u00e9tails de l'accord ne sont pas divulgu\u00e9s. Il n'est \u00e9galement pas pr\u00e9cis\u00e9 pour quels proc\u00e9d\u00e9s technologiques les blocs dot\u00e9s d'interfaces ont \u00e9t\u00e9 cr\u00e9\u00e9s. Il est seulement connu qu'ils sont adapt\u00e9s pour une int\u00e9gration dans des SoC fabriqu\u00e9s selon des \u00ab proc\u00e9d\u00e9s technologiques am\u00e9lior\u00e9s \u00bb. Aucune autre information n'est disponible.<\/p>\n
