Ресурсные и информационные конфликты в конвейерных системах

Автор работы: Пользователь скрыл имя, 10 Декабря 2012 в 21:45, курсовая работа

Описание работы

Конвейерная обработка основана на разделении исполняемой команды на сегменты, и выделении для каждой из них отдельного блока аппаратуры[1]. Сегментами конвейера могут быть оперативная память, арифметическое устройство, логическое устройство и др. Так же важную роль в конвейере играет организация передачи данных от одного сегмента к следующему. Конвейерную обработку можно использовать для совмещения этапов выполнения разных команд. Производительность при этом возрастает в разы, так как на различных тактах конвейера может выполняться несколько команд.
