The present application relates to the technical field of DRAM memory repair, in particular to a DRAM failure unit repair method based on SOC driving mapping adjustment.The present application detects the physical address of the failure CELL unit in the DRAM grain through a test device, generates repair mapping data, records the repair mapping data in the form of a two-dimensional code on the surface of the DRAM grain and stores the repair mapping data to a non-volatile memory, loads the repair mapping data to a driving program when the SOC starts, synchronously modifies the address mapping relationship of the MMU and the IOMMU through the driving program, and redirects the access to the failure physical address to a backup physical address.The present application simultaneously modifies the MMU and the IOMMU mapping at the driving level, realizes the unified address remapping of the CPU and the DMA device access path, makes the DRAM grain containing the failure unit be used in a reduced capacity, greatly reduces the PCBA cost, and does not need to be modified in hardware, and is flexible to implement.

This invention relates to a high-low frequency mixed-assembly adapter for signal switching, belonging to the field of connector technology. The high-low frequency mixed-assembly adapter includes a housing component and an insulator component and contacts disposed within the housing component. The insulator component includes a first insulator and a second insulator for mounting the contacts. The contacts include high-frequency contacts and low-frequency contacts. The low-frequency contacts on the first and second insulators are connected one-to-one by wires, and the high-frequency contacts on the first and second insulators are connected by a rigid-flexible plate adapter to achieve high-frequency signal switching. The insulator component also includes a straight sleeve between the first and second insulators, which is formed by two joined semi-cylinders. This invention eliminates the need for cable signal switching, allowing for selection of a suitable switching method based on the type and characteristics of the contacts, thus solving the problem of difficult signal switching in confined spaces while simultaneously supporting both high- and low-frequency signal switching.

The application discloses an LCD crosstalk suppression system and method through edge pixel gray scale adjustment, and the system comprises an edge pixel identification module configured to identify the pixel area of the display character edge through an image processing algorithm; a gray scale adjustment module connected to the edge pixel identification module, which adjusts the gray scale value of the edge pixel according to a preset adjustment strategy; and a display control module connected to the gray scale adjustment module, which sends the adjusted pixel data to the LCD for display. Through the cooperative work of the edge pixel identification module and the gray scale adjustment module, the application realizes effective suppression of the LCD crosstalk phenomenon and significantly improves the display quality. The adaptive threshold algorithm is adopted for edge detection, improving the accuracy and flexibility of edge pixel identification and adapting to the needs of different display scenarios. The application of the piecewise linear adjustment strategy makes the gray scale adjustment more precise, can more effectively suppress the crosstalk phenomenon and improve the display effect.
