Cela permet d&rsquo;ex\u00e9cuter des programmes sur des syst\u00e8mes qui ne sont pas con\u00e7us pour eux. Les \u00e9mulateurs, comme leur nom l&rsquo;indique, \u00e9mulent les fonctions d&rsquo;un syst\u00e8me sur un autre. Ainsi, le second syst\u00e8me se comporte comme le syst\u00e8me original, en essayant de reproduire exactement les comportements externes du premier syst\u00e8me.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comment l&rsquo;\u00e9mulation fonctionne-t-elle ?<\/h2>\n\n\n\n<p>En r\u00e9sum\u00e9, un \u00e9mulateur est un logiciel qui agit\u00a0comme du mat\u00e9riel. Dans la plupart des cas, cela signifie simuler toutes les capacit\u00e9s d&rsquo;un composant mat\u00e9riel sous forme de composant logiciel. De plus, les composants mat\u00e9riels qui sont \u00e9mul\u00e9s en tant que logiciels doivent fonctionner sans bugs, sinon l&rsquo;\u00e9mulateur ne fonctionnera pas correctement. La difficult\u00e9 de transformer des pi\u00e8ces mat\u00e9rielles avanc\u00e9es et uniques en logiciels fonctionnels est la raison pour laquelle les \u00e9mulateurs pour les consoles de jeux modernes prennent beaucoup de temps \u00e0 d\u00e9velopper. Il faut beaucoup de travail et d&rsquo;efforts pour que le processus d&rsquo;\u00e9mulation fonctionne, car le mat\u00e9riel moderne, comme les derni\u00e8res consoles de Sony et Microsoft, est extr\u00eamement complexe.<\/p>\n\n\n\n<p>Dans le cas de la Playstation, par exemple, un \u00e9mulateur doit imiter une puce sonore sp\u00e9ciale, une carte graphique, un processeur et bien d&rsquo;autres composants\u00a0sans m\u00eame envisager l&rsquo;\u00e9mulation de p\u00e9riph\u00e9riques comme les pilotes du lecteur CD. La partie\u00a0du\u00a0mat\u00e9riel la plus difficile \u00e0 \u00e9muler est g\u00e9n\u00e9ralement le processeur. C&rsquo;est un composant central de chaque ordinateur, des smartphones aux consoles de jeux vid\u00e9o. \u00c0 bien des \u00e9gards, le processeur est le composant informatique le plus important en mati\u00e8re d&rsquo;\u00e9mulation, car tous les autres composants lui sont directement li\u00e9s.<\/p>\n\n\n\n<p>Tous les processeurs ne sont pas identiques. La principale diff\u00e9rence entre les processeurs r\u00e9side dans leur jeu d&rsquo;instructions. Le jeu d&rsquo;instructions d\u00e9termine la mani\u00e8re dont un ordinateur ex\u00e9cute les commandes qu&rsquo;un programme lui donne. Un \u00e9mulateur cible un syst\u00e8me dont le jeu d&rsquo;instructions est diff\u00e9rent de celui de la machine h\u00f4te. Par exemple, le processeur de la PlayStation utilise un jeu d&rsquo;instructions connu sous le nom de MIPS, qui est diff\u00e9rent de celui d&rsquo;un ordinateur de bureau ou d&rsquo;un ordinateur portable qui utilisent g\u00e9n\u00e9ralement le jeu d&rsquo;instruction x86.<\/p>\n\n\n\n<p>avec futura<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>L&rsquo;\u00e9mulation est le processus qui consiste \u00e0 imiter un programme, une plateforme mat\u00e9rielle\u00a0ou logicielle sur un autre programme ou une autre plateforme.
