This invention relates to the field of metal material processing technology. It discloses a synergistic composite forming process for metal wire electroforming and drawing, comprising the following steps: first, surface cleaning and activation treatment of the base metal wire to remove oxide layers, oil stains, and impurities; then, feeding the pretreated wire into an electroforming device to deposit a metal plating layer, obtaining an initial electroformed composite wire; subsequently, direct online radial high-pressure drawing to achieve a dense bond between the electroformed layer and the base metal; followed by annealing of the composite wire; repeating the electroforming, drawing, and annealing steps at least once to complete multiple synergistic cycles; finally, testing the dimensional accuracy, mechanical properties, and interlayer bonding force of the composite wire, and cutting it into finished products after passing the tests. This invention employs an online tandem synergistic process of electroforming and drawing, avoiding plating oxidation and interface contamination. Radial high-pressure drawing can compact the plating layer, eliminate porosity, and improve bonding density.

This application relates to the field of integrated circuit design technology and discloses an on-chip network deadlock prevention method and system based on path reservation and credit backhaul. The core of the method lies in proactively locking virtual channel resources along the entire path via an independent reservation request packet along an adaptive route before data packet transmission. Combined with a "credit backhaul confirmation" mechanism, data packets are only allowed to be injected into the network after the source node receives an confirmation packet, thus transforming resource dependencies into unidirectional credit flow control. Simultaneously, reservation resource management is achieved by setting a distributed reservation state table in each router, and soft reservation and multi-path exploration mechanisms are introduced to improve resource utilization efficiency and path selection flexibility. This scheme fundamentally breaks the conditions for circular waiting, completely avoids deadlock, and eliminates the performance bottleneck of traditional methods when virtual channel resources are limited, achieving high determinism in data transmission, low blocking risk, and high efficiency in resource utilization.

The invention provides a bit-level parallel processing system for vector dot product calculation. The bit-level parallel processing system is used for processing dot product calculation of two vectors in parallel. The system comprises a plurality of parallel processing channels which are used for processing initial data packets obtained after preprocessing of two vectors in parallel and outputting final local sums of the processing channels, each processing channel is provided with a bidirectional routing node and a binary splitting node, and through cooperation of the two nodes, the final local sums of the two vectors are obtained. The processing channel can split the processed data packet and send the split data packet to other processing channels; the Bypass path is used for connecting the bidirectional routing nodes of the processing channels; and the global accumulator is used for calculating the sum according to the final local sum of all the processing channels. According to the technical scheme, the binary split nodes and the routing exchange nodes are added into the processing channels, so that the problems of performance bottleneck, resource waste, limited application scene and limited expandability caused by mutual isolation and independent calculation of the processing channels in the prior art are solved.

The invention discloses a network static routing configuration method based on compatibility of an SNMP protocol and a YANG model. The network static routing configuration method comprises the following steps: step 1, serialization conversion from the SNMP to the YANG: an idxBuf of the SNMP is coded into a staticroutears structural body compatible with the YANG; step 2, reverse synchronization from the YANG to the SNMP: after receiving the configuration parameter data and processing the configuration parameter data, the protocol stack module returns a corresponding processing result to the SNMP, and writes the FRR configuration state back to an MIB library through an IDB operation of the SNMP; and step 3, storing and recovering large-scale static routing configuration. According to the invention, the stock SNMP network management system can manage the YANG equipment without being transformed, so that the upgrading cost of an operator is reduced; through the adaptive compatibility solution of the application, the atomicity guarantee of the configuration transaction can be realized, the configuration change takes effect completely or rolls back completely, and the intermediate state is avoided; according to the method and the device, the performance bottleneck of large-scale static routing configuration storage is eliminated, and the configuration recovery speed when the equipment is restarted is optimized.

The application relates to the technical field of file storage management, and discloses a file storage management system of a cloud storage system, which comprises an access adaptation module, a metadata module, a slice version module, a deterministic mapping module, a container management module and a persistence control module. The deterministic mapping module performs stateless calculation based on a file identifier and a data block index number to generate a target container identifier and a virtual slot number. The container management module constructs a buffer container in the memory, ignores the discreteness of the virtual slot, and writes data blocks into a data storage area in a compact appending mode. The persistence control module drives effective data to be written into a disk according to a comparison result of a global version identifier and a historical version. The application eliminates the metadata bottleneck through deterministic routing, converts random I / O into sequential I / O through memory compact reorganization, and solves concurrent conflicts based on a lock-free mechanism, thereby significantly improving the throughput and expansibility of the storage system.

The PCIe system and the memory access method thereof disclosed by the application distribute the IOMMU function to the PCIe switching chip; the management module of the PCIe system obtains the identity of the physical endpoint device connected to the PCIe switching chip, the physical address of the peer device and the virtual address of the virtual endpoint device corresponding to the peer device during initialization, and delivers the information as routing and verification information to the input / output memory management unit of the PCIe switching chip. Thus, the input / output memory management unit in the PCIe switching chip can match the device identity and the virtual address in the message in the plurality of routing and verification information after receiving the message of a device, so as to convert the virtual address of the destination device in the message to obtain the physical address, and then route based on the physical address. It can be seen that the message does not need to pass through the host (root node) in the memory access mode, but only needs to pass through the PCIe switching chip, so as to reduce the DMA delay and eliminate the performance bottleneck of the root complex.

In the application, the resource utilization rate of the offshore wind power simulation platform is significantly improved, and the simulation calculation period is greatly shortened.
