Abstract:
A method of data transfer from a data source to a data sink, wherein said data source and said data sink each comprise a clock, said method comprising the steps of:sending first data from said data source to said data sink; sending a bus clock signal from said data source to said data sink; receiving said first data at said data sink; receiving said bus clock signal at said data sink; passing selectively said first data through an M segment subset of an N segment shift register, where M is less than N, where N is at least 2, where the length of the M segment subset is determined by the phase of a clock within said data sink at the time which said bus clock signal is received from said data source at said data sink, such that said first data is accessible at said data sink at a controllable predetermined time; and synchronizing said clocks of the data source and the data sink to a common frequency and starting point, each of said clocks outputting a local clock signal.
