Abstract
Methods and systems are disclosed for determining mask-value pairs for controlling access to a memory segment for a plurality of IDs. A first set of mask-value pairs is determined for a set of allowed identifiers (IDs) and a set of non-allowed IDs. Each mask-value pair of the first set matches at least one ID of the set of allowed IDs and does not match any of the IDs of the set of non-allowed IDs. Redundant mask-value pairs are removed from the first set to produce a second set. Subsets of mask-value pairs in the second set that match the entire set of allowed IDs are determined. The subset having the highest processing efficiency is determined and selected. A set of configuration data is generated that is configured to cause a memory management circuit to enforce access to the memory segment based on the selected subset of mask-value pairs.
