    摘要: A method including monitoring whether an externally originating signal reaches a predetermined threshold value in a host, producing an output value based on the monitoring, and identifying a power environment for the host based on the output value is described. Also described is a method for determining the power environment of a host. Systems and hosts for implementing the methods are also described.

    摘要: A subset of software objects stored in a first segment of non-volatile memory are identified as requiring frequent write operations or otherwise associated with a high endurance requirement. The subset of software objects are move to a second segment of non-volatile memory with a high endurance capacity, due to the application of wear leveling techniques to the second segment of non-volatile memory. The first and second segments of memory can be located in the same memory device or different memory devices.

    摘要: A microcontroller system, such as a system-on-a-chip integrated circuit, including a processor (e.g., a Von Neumann processor), memory, and a memory protection unit (MPU), where the MPU provides execute-only access rights for one or more protected areas of the memory. The MPU can allow instructions fetched from within a protected area to access data in the protected area while preventing instructions fetched from outside the protected area from accessing data in the protected area.

    摘要: A content-addressable memory (CAM) for managing the reallocation of erasable objects within a non-volatile memory is conceptually separated into two tables: a first table provides verification of whether or not a logical address has been reallocated and, if so, a second table provides the physical address of the reallocated erasable object.
