Method and apparatus for transmitting data

摘要

A semiconductor device comprising interface logic for transmitting data bursts across an interface. The interface logic is arranged to transmit bursts of data across the interface such that the start of a burst of data is substantially aligned with a symbol interval (SI) boundary. The interface logic is further arranged to apply an offset to the SI boundary at the start of the burst of data.

1. A method for transmitting data across an interface, the method comprising:
determining a first default symbol interval boundary; transmitting a first burst of data across the interface at a time based upon the first default symbol interval boundary; receiving a unit interval timing signal; receiving a symbol interval value; dividing the unit interval timing signal by the received symbol value to generate a symbol interval timing signal; determining a second default symbol interval boundary; transmitting a second burst of data across the interface, wherein the start of the second burst of data is aligned with the second default symbol interval boundary based on a start of the symbol interval timing signal in the second default symbol interval boundary; determining a third default symbol interval boundary, the time between the first and second default symbol interval boundaries being the same as the time between the second and third default interval boundaries; determining an offset based on a unit interval of a fixed amount of time; applying the offset to the third default symbol interval boundary at a start of a burst of data; and transmitting a third burst of data across the interface, wherein the start of the third burst of data is aligned with the offset and not aligned with the third default symbol interval boundary.
