Abstract
A PCI Express system and a method of transitioning link state thereof. The PCI Express system includes an upstream component, a downstream component and a link. The upstream component and the downstream component transmit data to each other via the link. When at least one of the upstream component and the downstream component stops data transmission under a normal working state and if the system idle time period reaches a threshold idle time, then transiting the link into a second link state.
