Abstract
A method of operating an interface device including a first elastic buffer is provided. The method of operating the interface device includes performing a link equalization operation, checking a transmission mode of the interface device, and determining a transmission parameter of the interface device based on a status of the first elastic buffer or a status of a second elastic buffer included in another interface device communicating with the interface device when the transmission mode is a transmission parameter adjustment mode.
Claims31
A method of operating an interface device including a first buffer and in communication with another interface device including a second buffer, the method comprising:
- initializing one or more parameters associated with a data transmission or reception of the interface device;
- receiving a status information indicating that an overflow or an underflow is generated at the second buffer;
- adjusting the one or more parameters associated with the data transmission or reception of the interface device based on the status information;
- and
- performing the data transmission or reception based on the adjusted one or more parameters.
A method of operating an interface device including a first buffer and in communication with another interface device including a second buffer, the method comprising:
- initializing one or more parameters associated with clock signals for a data transmission or reception of the interface device;
- adjusting the one or more parameters by a step value;
- performing at least one of transmission or reception of data to and from the other interface device communicating with the interface device based on the adjusted one or more parameters;
- receiving, from the other interface device, a status information indicating a status of the second buffer;
- and
- determining whether a pre-underflow or a pre-overflow is generated in the second buffer based on the status information.
An interface device comprising:
- a receiver configured to receive data;
- a buffer in communication with the receiver and configured to store the received data;
- a transmitter configured to output skip ordered-sets;
- wherein the receiver is configured to receive a second status information indicating a status of another buffer included in another interface device;
- wherein an interval between the skip ordered-sets outputted from the transmitter is derived from a link characteristic;
- wherein the skip ordered-sets are used to compensate a difference in frequencies between bit rates at two ends of a link.
