Abstract
Systems and devices for signal arbitration are described. A first asynchronous circuit can receive and sanitize a first non-persistent signal representing a first request to generate a first persistent signal. A second asynchronous circuit can receive and sanitize a second non-persistent signal representing a second request to generate a second persistent signal. A mutual exclusive circuit can arbitrate between the first persistent signal and the second persistent signal and output a grant signal to issue a grant. A control circuit can control an operation mode of the first and second asynchronous circuits based on a control signal, a first grant signal indicating a grant status of the first request, a second grant signal indicating a grant status of the second request, the first persistent signal and the second persistent signal.
