摘要：An apparatus and method for efficient communication of producer/consumer
buffer status are provided. With the apparatus and method, devices in a data processingsystem notify each other of updates to head and tail pointers of a shared buffer regionwhen the devices perform operations on the shared buffer region using signal
notification channels of the devices. Thus, when a producer device that produces data tothe shared buffer region writes data to the shared buffer region, an update to the headpointer is written to a signal notification channel of a consumer device. When a consumerdevice reads data from the shared buffer region, the consumer device writes a tailpointer update to a signal notification channel of the producer device. In addition,channels may operate in a blocking mode so that the corresponding device is kept in alow power state until an update is received over the channel.
