1. A system comprising:
a transmission device and a reception device that are connected through a link,
the reception device including:
a reception buffer configured to receive and store transaction layer packets; and
a reception flow controller configured to generate flow control packets by monitoring an occupation state of the reception buffer,
the transmission device including:
a transmission buffer configured to store pending transaction layer packets to be transferred to the reception device;
a transmission flow controller configured to control a flow of transaction layer packets to be transferred to the reception device based on the flow control packets received from the reception device; and
a dynamic frequency controller configured to control a frequency of an internal clock signal of the transmission device by monitoring a state of the transmission buffer and a state of the transmission flow controller.
