Abstract:
1. A method of coupling one or more outputs of a first circuit to one or more inputs of a second circuit, the core of the first circuit operating at a first clock frequency, the second circuit operating at a second clock frequency, the first clock frequency substantially higher than the second clock frequency, said method comprising: generating a first clock operating at the second clock frequency based on a clock running at the first clock frequency; transmitting data from the first circuit to a latch of the second circuit using an edge of the first clock operating at the second clock frequency; latching the transmitted data at the second circuit using an edge of a second clock operating at the second clock frequency; and adjusting a phase of the second clock to substantially match a phase of the first clock at a point where the second clock reaches a clock input of the latch, said adjusting further includes:
