摘要： A method and apparatus for restricting the execution of security sensitive instructions. A first security identification (ID) is associated with each of a plurality of instructions or a set of instructions that are to be executed by a processor. Software code running on the processor requests to execute at least one of the plurality of instructions or set of instructions. The processor obtains a second security ID associated with the software code running thereon and compares the second security ID with the first security ID. The processor executes the requested instruction or set of instructions providing that the second security ID matches the first security ID.

摘要： A memory management unit (MMU) is disclosed for managing a memory storing data arranged within a multiple memory pages. The memory management unit includes a security check receiving a physical address within a selected memory page, and security attributes of the selected memory page. The security check unit uses the physical address to access one or more security attribute data structures located in the memory to obtain an additional security attribute of the selected memory page. The security check unit generates a fault signal dependent upon the security attributes of selected memory page and the additional security attribute of the selected memory page. The security attributes of the selected memory page may include a user/supervisor (U/S) bit and a read/write (R/W) bit as defined by the ×86 processor architecture. The one or more security attribute data structures may include a security attribute table directory and one or more security attribute tables. The security attribute table directory may include multiple entries, and each entry of the security attribute table directory may include a present bit and a security attribute table base address field. A central processing unit (CPU) is described including the memory management unit (MMU), and a computer system is disclosed including the CPU. A method is described for providing access security for a memory used to store data arranged within multiple memory pages.

摘要： A microprocessor including a context save unit is provided. The context save unit is configured to periodically perform context saves. When the microprocessor receives an interrupt signal, the microprocessor enters the interrupt service routine without performing a context save. After completing execution of the interrupt service routine, the microprocessor restores the most recently saved context and begins executing the task at that saved context. The interrupt service routine is entered rapidly but the interrupt service routine does not include instructions for saving the registers which it utilizes to perform its function. The context save unit is configured to perform a context save at the occurrence of a variety of events. A fixed or variable time interval may be selected, and each interval includes several options.

摘要： A memory management unit (MMU) is disclosed for managing a memory storing data arranged within a plurality of memory pages. The MMU includes a security check unit (SCU) receiving a linear address generated during execution of a current instruction. The linear address has a corresponding physical address residing within a selected memory page. The SCU uses the linear address to access one or more security attribute data structures located in the memory to obtain a security attribute of the selected memory page. The SCU compares a numerical value conveyed by a security attribute of the current instruction to a numerical value conveyed by the security attribute of the selected memory page, and produces an output signal dependent upon a result of the comparison. The MMU accesses the selected memory page dependent upon the output signal.
