Leur cerveau est le processeur (ou CPU), un composant mat\u00e9riel programmable qui permet l\u2019ex\u00e9cution des logiciels (c\u2019est-\u00e0-dire les applications concr\u00e8tes). Le\u00a0jeu\u00a0d\u2019instructions (ISA) est une partie essentielle des processeurs. Elle constitue le vocabulaire que les logiciels utilisent pour indiquer les commandes (ou instructions) \u00e0 ex\u00e9cuter par le processeur. Elle repr\u00e9sente l\u2019interface de programmation entre le mat\u00e9riel et le logiciel.<br>De nombreux appareils informatiques modernes utilisent des ISA propri\u00e9taires, tels que ARM (la plupart des smartphones) et x86 (la plupart des PC et serveurs). Cependant, RISC-V, une ISA libre et ouverte cr\u00e9\u00e9e vers 2011 par Berkeley, bouscule les habitudes. Son ouverture favorise la concurrence et l\u2019innovation, car elle permet aux acteurs acad\u00e9miques et industriels de l\u2019impl\u00e9menter sans avoir \u00e0 payer de licences co\u00fbteuses. Cela est crucial dans cette \u00ab nouvelle \u00e8re dor\u00e9e pour l\u2019architecture informatique \u00bb, comme l\u2019ont d\u00e9clar\u00e9 les laur\u00e9ats du prix Turing 2017 (John Hennessy et David Patterson), o\u00f9 il faut trouver de nouvelles approches pour continuer \u00e0 am\u00e9liorer les performances et, surtout, l\u2019efficacit\u00e9 \u00e9nerg\u00e9tique.<br>Ce webinaire pr\u00e9sentera l\u2019ISA RISC-V et expliquera comment elle aide \u00e0 relever les d\u00e9fis li\u00e9s aux performances et \u00e0 l\u2019efficacit\u00e9 \u00e9nerg\u00e9tique.
