Asyncronous interface in a system on chip and a method of operating the same

The mobile system is connected to the first interface, and a first channel configured to transmit a payload in synchronization with the first clock signal at a first transmission rate on a first channel, pay for receiving the payload from the first channels is connected to the load store unit and the unit payload storage and a payload receiver for receiving in synchronization with the second clock signal to the second interface rate on a second channel a payload from the payload storage unit. The length of the second channel is the first clock signal is shorter than the length of the first channel, is asynchronous with the second clock signal.
