Abstract
A method for passing mastership of a bus is described. According to the method, it is determined whether to use the bus. If the bus is to be used, it is determined whether the bus is available. If the bus is available, the bus is accessed and a signal is generated to indicate that the bus is being accessed. A timer is also started and access to the bus is yielded when the timer expires. A processor that passes mastership to a shared resource is also described. The processor comprises a resource accessing unit. The resource accessing unit allows the processor to access a resource upon receiving a first signal from a component coupled to the resource. The resource accessing unit yields access of the resource to the component upon receiving a second signal from the component.
