The project has broken through technical bottlenecks including high-speed VIDEO control technology, LVDSAFE technology, and DADFShading algorithm, reaching the international advanced level of its kind. By researching heterogeneous multi-core SoC architecture, we have completed the hardware-software co-design of image processing and printing control algorithms, broken through the limitations of algorithm allocation under single-core or homogeneous multi-core scenarios, and solved the energy efficiency issues of SoC chips. By combining high-performance hardware floating-point arithmetic units and high-precision optical color sensors, a high-performance color closed-loop correction mechanism has been established, realizing high-performance color correction for color printers. For the first time, the control of A4 DADF scanners has been realized. The technical problem of slow speed caused by large data volume in high-speed scanning of A4 DADF has been solved via LVDSAFE technology, and high-quality output of DADF scanned images has been achieved based on the DADFShading algorithm. It is the first domestic entity to fully independently master core technologies including color engine control and color correction, realizing high-speed color printing and copying functions. During the project period, the color printing master control SoC was integrated into self-developed A4 color printers and A3 color copiers for mass production introduction and development. It passed pilot production and finalization inspection, reaching stable mass production levels, and was applied in industrialization on self-developed A4 color printers.
