ABSTRACT:
The invention relates to the processing of state information such as interrupt status in a hierarchical network of nodes having a tree configuration. There is a root node at the top of the hierarchy, one or more intermediate nodes, and a plurality of leaf nodes at the bottom of the hierarchy. Each leaf node is linked to the root node by zero, one or more intermediate nodes. Each leaf node maintains information about one or more interrupt states, and each intermediate node maintains information derived from the interrupt states of leaf nodes below it in the hierarchy. This interrupt information is then processed by navigating from the root node to a first leaf node having at least one set interrupt state which is then masked out. The status of any intermediate nodes between this first leaf node and the root node is then updated if appropriate to reflect the fact that the particular interrupt state at the first leaf node is now masked out. These steps are then repeated with respect to all the other leaf nodes in the network having at least one interrupt state.
