A processing device includes a process portion and a processor. The process portion performs medium processing on a transfer medium, subsequent to or prior to ejection of ink forming an image to be transferred from the transfer medium to a transfer-receival medium. The processor causes the process portion to perform one of the medium processing of forming additional information on the transfer medium in a non-transfer mode, or the medium processing of implementing a restriction procedure on the additional information formed on the transfer medium, or the medium processing of implementing an image transfer procedure on the image formed on the transfer medium and not implementing an information transfer procedure on the additional information formed on the transfer medium.

The invention discloses a data path verification method and device and a nonvolatile storage medium. The method comprises the steps that a to-be-verified standardized input file is obtained, the standardized input file adopts a preset standardized file format, and the standardized input file comprises parameters of a target test case and a predicted test result of the target test case; the parameters comprise a transmission mode of a target data path, a packet sending number of the target data path and a packet sending address of the target data path, and the target data path is a data path for transmitting doorbell data to the memory access controller; based on the standardized input file, performing a simulation test on the target test case to obtain an actual test result; the predicted test result is compared with the actual test result, a target verification result is obtained, and the target verification result comprises verification passing or verification failure. The technical problems that a traditional data path verification method needs manual operation, so that efficiency is low, and errors are prone to occurring are solved.

The application discloses an inline small data transmission method and system based on an NVMe command queue, and belongs to the field of electronic digital data processing. The application aims at the problem that the PRP / SGL mechanism in the existing NVMe protocol takes 4KB physical pages as the minimum transmission granularity, leading to bandwidth amplification and redundant direct memory access operation in the small data scene. The submission queue is expanded into a mixed transmission channel of commands and data. When the effective load is less than or equal to a preset threshold, the host side segments the data, constructs an NVMe command containing a combined command type code, and writes the command and the data segment as a continuous 64-byte entry into the submission queue in sequence. The solid state disk controller sequentially reads the submission queue, identifies the inline transmission mode according to the combined command type code, directly extracts the data segment or triggers the direct memory access engine to perform multi-source aggregation transmission. The application eliminates redundant direct memory access transactions, improves the high-speed peripheral component interconnect link bandwidth utilization, and reduces the small data transmission delay.

A method and apparatus for displaying a target application across one or more devices is disclosed. The method includes determining a functional module within the target application running on a first device, where the module comprises one or more pages. A transfer parameter and a configuration parameter of the functional module are parsed. The transfer parameter identifies the target device—either the first device or a second device—for display of the module, while the configuration parameter defines display-related information. Based on the transfer parameter, the functional module is selectively transferred to and laid out on the determined target device. The system supports flexible multi-device display scenarios, including fixed, sequential, exclusive, or terminal transfer modes, enabling adaptive rendering of application modules across heterogeneous devices.

This invention relates to the field of data processing technology, and discloses an FPGA update method, apparatus, device, and program product based on a GLink control system. The method includes: acquiring the operating mode of the node to be updated and a first target update file corresponding to the operating mode; determining the transmission mode of the first target update file based on the operating mode; and sending the first target update file to a non-volatile memory based on the transmission mode, so that the non-volatile memory updates the initial file to a second target update file; wherein the non-volatile memory stores the initial file, and the second target update file is used for FPGA updates. This invention controls the FPGA via the GLink bus, allowing firmware update files to be transmitted via a network or other general-purpose interfaces, eliminating the need for a specific manufacturer's dedicated JTAG downloader. Furthermore, remote upgrades via the network eliminate the need for on-site engineer operation, reducing manpower and time costs while avoiding the risk of operational errors.

The application provides a high-efficiency covert channel attack and information leakage method based on multiple interrupt driving, which is called Compound-INT. Four stable and controllable interrupt types (rtc0, PMI (Performance Monitor Interrupts), MCP (Machine Check Polls), IWI (IRQ Work Interrupts), and TLB (TLB shootdowns)) are screened out by analyzing the / proc / interrupts interface in an operating system to construct an efficient covert channel. The method supports two transmission modes, single bit and multi-bit. Single bit realizes data coding by controlling the interrupt triggering frequency, and multi-bit combines synchronous and asynchronous transmission modes to improve bandwidth and anti-interference, and adapt to the complex conditions of a multi-core environment. In addition, the application realizes the leakage of the existence state of a target file in a restricted directory by using the PMI interrupt, and speculates the structure information of a deep neural network (DNN) model by using the TLB shootdowns interrupt mode, thereby expanding the application scenarios of the covert channel. Experimental results show that the method has high transmission rate, low error rate and strong robustness, and provides a new idea for the security research of the interrupt mechanism of an operating system.

The present invention provides a processing apparatus, a control method, and a transfer medium that contribute to suppressing the transfer of additional information from the transfer medium to the transfer medium during the transfer process. [Solution] The processing apparatus comprises a processing unit and a CPU. The processing unit performs media processing on the transfer medium 51 after the ink has been ejected or before the ink is ejected. The ink forms an image L0 that is transferred from the transfer medium 51 to the transfer medium 61. The CPU causes the processing unit to perform media processing to form additional information L2 on the transfer medium 51 in a non-transfer mode. The non-transfer mode is a mode in which, in the transfer process in which the image L0 is transferred from the transfer medium 52 to the transfer medium 61, the additional information L2 is not transferred from the transfer medium 52 to the transfer medium 61.
