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.

摘要： A method and apparatus for controlling access to segments of memory having security data stored therein is provided. A security check unit maintains information for a plurality of segments of memory regarding whether each of these plurality of segments has secure data stored therein. A hint directory maintains information regarding whether any of a plurality of these segments has secure data stored therein. The hint directory is capable of bypassing the security check unit when it receives an address that falls within a plurality of the segments that have been indicated as being free from secure data. When the hint directory determines that a received address falls within one of a plurality of segments that contain secure data, then the address is passed to the security check unit for a closer examination.

摘要： A microprocessor including a context file configured to store multiple contexts is provided. The microprocessor may execute multiple threads, each thread having its own context within the microprocessor. In one embodiment, the present microprocessor is capable of executing at least two threads concurrently: a task and an interrupt service routine. Interrupt service routines may be executed without disturbing a task's context and without performing a context save operation. Instead, the interrupt service routine accesses a context which is independent of the context of the task. In another embodiment, the context file includes multiple interrupt service routine contexts. Multiple ISR context storages allow for nested interrupts to be performed concurrently. In yet another embodiment, the microprocessor is configured to execute multiple tasks and multiple interrupt service routines concurrently. Multiple tasks may be executed concurrently by the microprocessor in addition to executing multiple interrupt service routines concurrently. In still another embodiment, the microprocessor includes a primary context and multiple local context storages coupled to each of its execution units. A given execution unit may execute instructions referencing the primary context or the local context connected thereto.
