SECURITY CONFIGURATION FOR MEMORY ADDRESS TRANSLATION FROM OBJECT SPECIFIC VIRTUAL ADDRESS SPACES TO A PHYSICAL ADDRESS SPACE

Systems, apparatuses, and methods related to securing memory access made using virtual addresses are described. For example, a memory coupled to the computer processor can store instructions of routines of predefined, non-hierarchical domains. The computer processor can store separate tables for the different domains. A virtual address is configured with an object identifier and an offset of a location within the object represented by the object identifier. At least the object identifier of the virtual address is hashed to generate an index into a table of the current domain in which the processor is executing instructions. An entry retrieved from the table using the index provides a security configuration for the object represented by the object identifier. The processor secures memory access according to the security configuration in response the execution of an instruction that uses the virtual address.
