Abstract
In a disclosed example of a method, a requested value of a target register may be specified as a precondition to performing a requested read or write operation. The requested read or write operation may be generated by a requesting device, such as a processor, and sent over a bus to a peripheral device containing the target register. The target register may be polled internally to the peripheral device without generating additional bus traffic between the requesting device and the peripheral device. A ring topology may be used to internally poll the target register and to perform the requested read or write operation when the polled value of the target register equals the requested value.
