Abstract
Systems, circuits, and methods for clock domain crossing for an interface between logic circuits are provided. A circuit is configured to allow an exchange of signals between a first logic circuit clocked using a first clock signal having a first frequency and a second logic circuit clocked using a second clock signal having a second frequency different from the first frequency. The circuit includes a first circuit segment configured to receive a first control signal to select the second logic circuit and a second control signal to indicate an initiation of an access operation, and ensure that the second control signal maintains a relationship with the first control signal based on the second clock signal. The circuit further includes a second circuit segment configured to receive, from the second logic circuit, a third control signal indicating a readiness of the second logic circuit to complete the access operation.
