Архитектура PCI Express
PCI Express обеспечивает высокую производительность ввода / вывода инфраструктуры для Настольные системы со скоростью передачи от 2,5 Гига переводов в секунду на PCI Express x1 полосу движения для Gigabit Ethernet, ТВ-тюнеры, 1394a / б контроллеров, так и общего назначения I / O. Архитектура PCI Express обеспечивает высокую производительность графической подсистемы инфраструктуры для Настольных системы удвоение возможностей существующих конструкций с AGP8x скорость передачи 4,0 гигабайт в секунду на x16 PCI Express полосу движения для графических контроллеров. ExpressCard использования PCI Express интерфейс, разработанный группой PCMCIA для мобильных компьютеров. PCI Express Расширенные функции управления питанием помогают продлить жизнь батареи и платформы, чтобы дать возможность пользователям работать в любом месте, без источника питания переменного тока.
Широкое внедрение
PCI Express в мобильных, корпоративных и коммуникационных сегментов позволяет сближение через повторное использование единой технологии интерконнекта.
PCI-E является последовательной шиной, которая использует две низковольтных дифференциальные пары LVDS, в 2,5 Гбит / с в каждом направлении [одной передачи, и одину получает пару]. PCI Express поддерживает 1x [2,5 Гбит], 2x, 4x, 8x, 12x, 16x, 32x и ширины шины [приема / передачи пар].
Дифференциальных контакты [Lanes], перечисленные в контактный из таблицы выше, LVDS что расшифровывается как: низкая сигнализации в дифференциальной схеме. |
