This disclosure provides a controller, address management method, and system for a phase-change memory (PCM). The method includes: determining the address mapping mode of the PCM; if it is a static mapping mode, mapping a first source address to a first destination address based on a preset mapping table; if it is a dynamic mapping mode, matching a corresponding address mapping rule according to a dynamic scenario, and mapping a second source address to a second destination address based on the address mapping rule; if it is a hybrid mapping mode, mapping a third source address to a third destination address based on a preset mapping table, controlling the PCM to perform read operations based on the third destination address; and matching a corresponding address mapping rule according to a dynamic scenario, mapping a fourth source address to a fourth destination address based on the address mapping rule, and controlling the PCM to perform write operations based on the fourth destination address. This application can reduce the read latency of the PCM, improve the write performance and media lifetime of the PCM, and achieve a balance between read and write performance.

The invention provides an ais-based workflow work order configuration method and system and a medium, and the method comprises the steps: embedding an aims engine in a Vue3 architecture, and constructing to obtain a front-end platform configured with a visual configuration management interface; pre-configuring an ais template through a visual configuration management interface, and storing a corresponding template JSON configuration according to a template identifier; when a link in a workflow is configured, establishing a static mapping relationship between the link in the workflow and the corresponding template identifier by specifying the corresponding template identifier; according to the static mapping relation, template JSON configuration corresponding to the link is obtained, and then the template JSON configuration and work order basic data are constructed to obtain a JSON configuration file; and according to the JSON configuration file, rendering to generate a corresponding display interface. According to the method, the complex and dynamic workflow work order can be quickly, efficiently and flexibly generated, the development cost is remarkably reduced, and the delivery efficiency and the system adaptability are improved.

The invention discloses a unified cryptographic interface management system and method based on hardware feature automatic identification. The system obtains a manufacturer identifier VID and a product identifier PID of the safety equipment by scanning a USB bus, dynamically loads a corresponding manufacturer driver library according to a built-in static mapping table during deployment, and analyzes and constructs an SKF standard interface function pointer table by using a dynamic symbol; when the equipment is opened, a packaging handle containing a real equipment handle and a function pointer table is generated, and subsequent interface calling is specifically realized by unpacking the handle and routing to a manufacturer; and meanwhile, a global unique equipment identifier is generated by adopting a manufacturer name: equipment model combination format, so that the conflict of equipment names of multiple manufacturers is avoided. According to the scheme, user configuration is not needed, plug-and-play and transparent calling of multi-brand UKEYs are supported, and the compatibility and management efficiency of national secret equipment are improved.

The invention relates to the technical field of data storage, and discloses a UFS-oriented high-speed direct data path performance test method, which comprises the following steps: in a user space processing flow, creating a test thread bound to a specific CPU processor core, multiplexing a data cache pool by the test thread to construct an input and output request, and issuing the input and output request through an input and output control interface; in a kernel space processing flow, pre-established mapping and page locking on a user space data cache pool are utilized, and input and output requests are directly dispatched to a corresponding multi-command queue hardware queue in a UFS device driver to be executed. By bypassing a Linux block device layer, a direct data path from a user space to a UFS driver is established, so that the input and output paths are greatly shortened, and the sequential and random read-write performance is remarkably improved; by establishing a static mapping relation among the threads, the CPU processor cores and the multi-command queue hardware queue, multi-core resource competition is effectively reduced, and the parallel processing capacity of UFS equipment is fully released.

The invention discloses a mapping storage method, device and equipment of an SSD of DRAMLess and a medium, and relates to the technical field of solid state disks, and the mapping storage method comprises the steps that a static mapping storage area is arranged in a flash memory space of the solid state disk, and physical blocks of the static mapping storage area work in a static single-layer unit mode; in the running process of the solid state disk, dynamically distributing physical blocks of areas except the static mapping storage area to serve as storage space of mapping table data, and forming a dynamic mapping storage area; selecting a target storage area from the static mapping storage area and the dynamic mapping storage area for mapping table data to be written according to a preset selection strategy; and writing the mapping table data into the target storage area. According to the invention, the problem of local excessive wear is obviously improved, so that the overall service life and reliability of the DRAMLess SSD are greatly improved while the read-write performance is ensured.
