Abstract
A computing device having partitions, and a method of communicating between partitions, are disclosed wherein each partition comprises at least one address area readable but not writable from the other of the at least two partitions. In one embodiment one partition sends to the other partition a request for information, which information is in the other partition in an address area not accessible to the one partition, the other partition copies the information to an address area accessible to the one partition, and the one partition reads the information from the accessible address area. In another embodiment the at least one accessible address area of each partition includes a data area and a consumer pointer indicating the position to which that partition has read the data area in another partition.
