Abstract
A plurality of physical addresses are derived from address information stored in an address memory of a bridge or other multi-port communication device, wherein the stored address information does not directly specify all the addresses. In a first embodiment, the stored addressing information specifies a single address value from a first block of preferably consecutive address values. A processor uses the first address value to derive a second address value from a second, different block of preferably consecutive address values, and then assigns both as, e.g., port addresses. In a second embodiment of the invention, the address memory stores address information which specifies a range of preferably consecutive address values, for instance, the first and last address values of the range. A processor fetches these address values from the address memory, identifies all address values within the range, and assigns them as, e.g., port addresses.
