Abstract
An integrated circuit device for use in a node of a communication system is provided. The integrated circuit device includes a memory configured to store data written thereto by a receiver associated with the node in accordance with a receiver clock, and to read data therefrom by a transmitter associated with the node in accordance with a transmitter clock. The integrated circuit device also includes a control logic circuit that is in communication with the memory, and is configured to send a control signal to the transmitter to adjust a speed of the transmitter clock responsive to an operating condition of the memory.
Claims20
An integrated circuit device for use in a node of a communication system, the device comprising:
- a memory configured to store data written thereto by a receiver associated with the node in accordance with a receiver clock, wherein the data is read therefrom by a transmitter associated with the node in accordance with a transmitter clock;
- and
- a control logic circuit in communication with the memory, configured to send a control signal to the transmitter to adjust a speed of the transmitter clock responsive to an operating condition of the memory.
A method, for use in a communication system having at least one node, for controlling a transmitter clock associated with the at least one node, the method comprising the steps of:
- writing data to a memory associated with the at least one node by a receiver associated with the at least one node in accordance with a receiver clock;
- reading data from the memory by a transmitter associated with the at least one node in accordance with a transmitter clock;
- and
- sending a control message from a control logic circuit associated with the at least one node in communication with the memory to the transmitter to adjust a speed of the transmitter clock responsive to an operating condition of the memory.
An article of manufacture comprising a machine-readable storage medium having one or more software programs stored therein, for use in a communication system having a at least one node, the at least one node being operative under control of the one or more software programs to perform the steps of:
- writing data to a memory associated with the at least one node by a receiver associated with the at least one node in accordance with a receiver clock;
- reading data from the memory by a transmitter associated with the at least one node in accordance with a transmitter clock;
- and
- sending a control message from a control logic circuit associated with the at least one node in communication with the memory to the transmitter to adjust a speed of the transmitter clock, responsive to an operating condition of the memory.
