Embodiment Construction

[0023] Hereinafter, examples of implementation of the present invention will be described. In the interest of clarity, not all features of a practical implementation of the invention are described in this specification. It should of course be appreciated that in developing any such actual embodiment, many implementation-related determinations must be made in order to achieve the inventor's specific goals, such as compliance with system-related and Business-Related Restrictions. In addition, it should be understood that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of one with ordinary knowledge in the art having reference to the present disclosure.

[0024] Such as figure 1 As shown in , embodiments of the present invention provide memory access using a secure access system. Embodiments of the present invention provide a system of memory access tables to provide security during memory accesses initiated by one...

Abstract

A method and an apparatus for performing a virtual memory access. A software object is executed. A security level for the software object is established. A secondary table is established. A memory access request based upon the executing of the software object is received. At least one security level that corresponds to a segment in the secondary table 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. A virtual memory address based upon the secondary table 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.

Description

technical field [0001] The present invention generally relates to computer system operations, and more particularly to a method and apparatus for performing security configuration based on physical addresses to provide a secure memory access. Background technique [0002] Computers or computer systems are an important element in many of today's industrial and home applications. There are many systems, such as manufacturing systems, power systems, product distribution systems, file systems, etc., that are powered by computer systems using processors. These processors perform various tests and execute multiple software programs that interact with each other. Input / output devices often allow the processing operations of the processor and software programs. A standard level of security is desired during processor operation so that certain software structures (eg, software objects, subroutines, stand-alone programs, etc.) can be controlled to give priority over other software s...
