Abstract:
An apparatus for communicating signals between a first circuit operating at a first frequency and a second circuit operating at a second frequency, wherein the first frequency is higher than the second frequency, the apparatus comprising:a control circuit to receive a clock signal at the first frequency and one or more of a clock signal at the second frequency and a set of one or more bits indicating a relationship between the first frequency and the second frequency, the control circuit to determine the relationship between the first frequency and the second frequency;a first buffer circuit to receive signals from the first circuit and to output signals to the second circuit, the first buffer circuit to receive a first control signal from the control circuit; anda second buffer circuit to receive signals from the second circuit and to output signals to the first circuit, the second buffer circuit to receive a second control signal from the control circuit;wherein the first and second control signals control the first buffer and the second buffer to communicate signals between the first circuit and the second circuit such that signals communicated to the respective circuits are available during predetermined time periods.
