Abstract
One embodiment of the present invention provides a circuit that preferentially grants requests. This circuit monitors at least two inputs for request signals and at least two inputs for enable signals, wherein each request signal is associated with a corresponding enable signal. If any enable signal is asserted and only one request signal is asserted, the circuit asserts a grant signal associated with the asserted request signal. Otherwise, if a single enable signal is asserted and multiple request signals are asserted, the circuit preferentially asserts the grant signal of the request signal associated with the asserted enable signal.
