Abstract
In an example, a system includes an SRAM configured to store a plurality of access control rules, where each rule is stored in a separate row. The SRAM is configured to store a plurality of context entries, where each context entry is stored in a separate row. The system includes a controller configured to receive a request for an access control rule for a memory location from a first context. The controller is configured to search one or more access control rules for the first context, where access control rules for the first context are stored in a binary tree format. The controller is configured to, responsive to finding the access control rule for the memory location, return the access control rule to the first context. The controller is configured to, responsive to not finding the access control rule, return a null notification to the first context.
