Abstract: System and methods are provided for storing address-mapping data from a storage device on a processing system. Address-mapping data is stored on a non-volatile memory of a storage device, the address-mapping data indicating mapping from logical addresses to physical addresses of the non-volatile memory of the storage device. The address-mapping data is transmitted from the non-volatile memory to a processing system. In response to a request to access a logical address of the non-volatile memory, part of the address-mapping data is transferred from the processing system to a volatile memory of the storage device, the part of the address-mapping data being associated with a mapping from the logical address to a physical address of the non-volatile memory.

Abstract: Systems and methods are provided for performing memory management in a storage device. The systems and methods may include receiving, at the storage device, a command to perform an operation on a data segment, wherein the command includes an indication of access properties associated with the data segment. The systems and methods may further include determining a plurality of physical memory locations associated with the data segment, and performing memory management on the plurality of physical memory locations based on information about the access properties.

Abstract: Systems and methods for optimizing lifespan of a storage device are provided. A request to store data to the storage device is received. The storage device includes a plurality of regions. A determination is made that a first group of regions of the plurality of regions is associated with an error measurement threshold that is lower than a second group of regions of the plurality of regions. A region of the storage device that is in the first group of regions is selected based on the determination. The data is stored to the selected region.

Abstract: A real time control system capable of accurately supporting the real time characteristics of a multitasking digital signal processor (DSP) which requires an operating system (OS), is provided. In this real time control system, a ready queue and a waiting queue each includes a priority link having information indicating the first task control block and the last task control block among task control blocks of the same priority in a multitasking environment, and a queue link having information indicating the first task control block and the last task control block among tasks for a DSP according to the purpose of use. Timer control blocks are managed using a timer wheel having a pointer arrangement structure. A memory is divided into an internal memory and an external memory, and thus the internal and external memories are managed respectively at user request.
