<p>A method and an apparatus for performing a virtual memory access. A software object (350) is executed. A security level for the software object (350) is established. A secondary table (430) is established. A memory access request based upon the executing of the software object (350) is received. At least one security level that corresponds to a segment in the secondary table (430) is determined. A match between an execution security level and a security level associated with a segment being accessed is verified in response to an execution of the software object (350). A virtual memory address based upon the secondary table (430) in response to a match between the execution security level and the security level associated with the segment being accessed is determined. A physical memory location corresponding to the virtual memory address is located. A portion of a memory based upon locating the physical memory location is accessed.</p> |
