Abstract
A clocking system and method in a point-to-point bus configuration overcomes the limitations of conventional approaches. In one embodiment, the present invention ensures the same phase relationship for the write clock in the write direction for all data transfers between modules, and similarly the same phase relationship for the read clock in the read direction for all data transfers between modules, regardless of module location. In another embodiment, on a given module, all transfers of data between a data buffer and a memory device in both read and write directions are clocked by a read clock signal and a write clock signal that have the same phase relationship and have the same propagation delay as the data bus between the buffer and the memory device.
