An input/output store instruction is handled. A data processing system includes a system nest coupled to at least one input/output bus by an input/output bus controller. The data processing system further includes at least a data processing unit including a core, system firmware and an asynchronous core-nest interface. The data processing unit is coupled to the system nest via an aggregation buffer. The system nest is configured to asynchronously load from and/or store data to at least one external device which is coupled to the at least one input/output bus. The data processing unit is configured to complete the input/output store instruction before an execution of the input/output store instruction in the system nest is completed. The asynchronous core-nest interface includes an input/output status array with multiple input/output status buffers.

A data storage device restoring method is provided, which is adapted to a data storage device. The data storage device includes an SSD controller, a power management circuit, a non-volatile memory, and a reset circuit. The data storage device restoring method includes: the power management circuit determines whether a normal signal from the SSD controller is received within a predetermined time; if not, the power management circuit resupplies power to the data storage device but stops supplying power to the non-volatile memory, thereby the SSD controller stays in a read-only memory mode to automatically execute the data storage device restoring process.

Techniques for computer memory management are disclosed herein. In one embodiment, a method includes in response to receiving a request for allocation of memory, determining whether the request is for allocation from a first memory region or a second memory region of the physical memory. The first memory region has first memory subregions of a first size and the second memory region having second memory subregions of a second size larger than the first size of the first memory region. The method further includes in response to determining that the request for allocation of memory is for allocation from the first or second memory region, allocating a portion of the first or second multiple memory subregions of the first or second memory region, respectively, in response to the request.

A high-capacity system memory may be built from both quasi-volatile (QV) memory circuits, logic circuits, and static random-access memory (SRAM) circuits. Using the SRAM circuits as buffers or cache for the QV memory circuits, the system memory may achieve access latency performance of the SRAM circuits and may be used as code memory. The system memory is also capable of direct memory access (DMA) operations and includes an arithmetic logic unit for performing computational memory tasks. The system memory may include one or more embedded processor. In addition, the system memory may be configured for multi-channel memory accesses by multiple host processors over multiple host ports. The system memory may be provided in the dual-in-line memory module (DIMM) format.

A device includes a plurality of reconfigurable resources, a bus, and a configurator. The bus interconnects the plurality of reconfigurable resources. The configurator is configured to deterministically compute a segmented interconnect configuration for the bus based on operational parameters associated with the device and operational constraints associated with program modules to be executed by the plurality of reconfigurable resources.

Methods, systems, and devices for authenticating software images are described. A system may include one or more control units that use software images for managing different functions of the system. The system may also include a secure storage device configured to validate or authenticate the software images used by the different control units of the system. A software image of a control unit may be authenticated by generating a first hash associated with a portion of its underlying source code and generating a second hash associated with a corresponding portion of the source code of the copy of the software image stored to the secure storage device. Different patterns of the source code of the software images may be used to generate the hashes. The first hash and second hash may be compared, and the software image may be authenticated based on the hashes matching.

Techniques for improved mobile application architectures and service communication protocols are discussed herein. Some embodiments may include a mobile device configured for providing a mobile application including multiple service applications. The service applications may execute asynchronously and in separate containers, providing service orientated architecture (SOA)-like services with respect to other portions of the mobile application, or even external applications. The separation of a monolithic mobile application into separate service applications provide advantages in terms of application performance, development, and maintenance. For example, a subset of all service applications may be started up, and executed on demand to improve device resource utilization efficiency.
