Abstract:
A method for initializing deterministic data transfers between a first device and a second device, wherein the first device operates according to at least a first clock having a first clock rate, wherein a second device operates according to at least a second clock having a second clock rate, wherein a ratio between the second clock rate and the first clock rate is an integer number greater than or equal to one, the method comprising:the first device receiving a serial data stream in one or more synchronous data transfers, wherein the serial data stream includes at least one ratio bit, wherein the at least one ratio bit is encoded with the ratio between the second clock rate and the first clock rate; the first device using the ratio bit to determine an edge of the second clock; and the first device transmitting a first source-synchronous clock to the second device on the edge of the second clock.
