PROCESSEUR d'Émulation et de verrouillage à une vitesse d'horloge

J'ai écrit un Z80 émulateur il y a plusieurs années, et pour faire le cycle d'exécution exacte, j'ai divisé la fréquence d'horloge dans un certain nombre de blocs de petite taille et avait le cœur exécuter que de nombreux cycles d'horloge. Dans mon cas, je l'ai attachée à la cadence du système de jeu, j'ai été à l'émulation. Chaque opcode savait combien de cycles qu'il a fallu pour exécuter et le noyau serait de continuer à courir opcodes jusqu'à ce que le nombre spécifié de cycles ont été exécutés. J'ai eu un extérieur exécuter en boucle pour exécuter le cœur de processeur, et exécuter d'autres parties du système émulé et puis dormir jusqu'à l'heure de début de l'itération suivante.

EDIT: Ajout de l'exemple de l'exécution de la boucle.

int execute_run_loop( int cycles )
{
    int n = 0;
    while( n < cycles )
    {
        /* Returns number of cycles executed */
        n += execute_next_opcode();
    }

    return n;
}

Espère que cette aide.

Que jfk dit, la façon la plus courante de le faire est cravate la vitesse du processeur pour le rafraîchissement vertical de l' (émulé) sortie vidéo.

Choisissez un nombre de cycles pour exécuter chaque image de la vidéo. Ce sera souvent spécifiques à la machine, mais vous pouvez le calculer par quelque chose comme :

cycles = clock speed in Hz /required frames-per-second

Puis, vous obtenez également de faire un sleep jusqu'à ce que la mise à jour vidéo est frappé, à ce stade, vous commencez le prochain n cycles de CPU émulation.

Si vous imiter quelque chose en particulier, alors vous avez juste besoin de regarder les fps taux et la vitesse du processeur pour obtenir ce droit environ.

EDIT: Si vous n'avez pas de temps externe exigences, alors c'est normal qu'un émulateur juste courir aussi vite qu'il le peut. Parfois, c'est un effet voulu et parfois pas 🙂

Oui, comme dit précédemment, la plupart du temps vous n'avez pas besoin d'un CPU émulateur pour émuler les instructions à la même vitesse de la vraie chose. Quel utilisateur de percevoir, c'est la sortie de calcul (c'est à dire de l'audio et de la vidéo sorties) donc vous avez seulement besoin pour être en phase avec ces sorties qui ne signifie pas que vous devez nécessairement une UC la vitesse de l'émulation.

En d'autres termes, si le frame rate de la vidéo d'entrée est, disons, 50 hz, puis de laisser le CPU émulateur de courir aussi vite qu'il peut pour attirer l'écran, mais assurez-vous de la sortie de la cadres de l'écran à la bonne vitesse (50Hz). À partir d'un point de vue externe de votre émulateur émule à la bonne vitesse.

En essayant d'être le cycle exact même le temps d'exécution est un non-sens sur un multi-tâches OS comme Windows ou Linux, car l'émulateur du temps d'instruction (typiquement moins de 1 vintage des années 80 Processeurs) et de la planification de la plage horaire de l'OS modernes sont comparables.

Essayer à la sortie de quelque chose à 50Hz taux est beaucoup plus facile que vous pouvez faire de très bonne qualité sur les machines modernes

Je suis en train de faire quelque chose d'un peu plus généraux de cas d'utilisation, tels que la capacité de convertir le temps, à une estimation de la quantité d'instructions et vice versa.
