Problems solved by technology

Due to the performance limitation of the general processor on the PC and the transmission speed limitation of the parallel interface, the current digital printing machine cannot process the printing image with a large amount of data in real time, and the printing speed is also far behind that of the printing machine using traditional printing technology. The advantages of high precision and low pollution of digital printing machines cannot be widely used in actual production

Abstract

The invention discloses a high-speed digital printing processing system based on an embedded processor. The system comprises a gigabit Ethernet interface, an RS 485 interface, a Rapid input / output (IO) interface, the embedded processor and a field programmable gate array (FPGA), wherein the embedded processor comprises an instruction receiving unit, an instruction processing unit, an instruction output unit, a data receiving unit, a compressed data caching unit, a data decompressing unit, a decompressed data caching unit and a data output unit. According to the system, the high-performance processor and the FPGA serve as the core, high-speed transmission of printing data from a personal computer (PC) to a printing nozzle is finished through the gigabit Ethernet interface and the Rapid input / output interface, the processing and the forwarding of a printing instruction are finished through the gigabit Ethernet interface and the RS 485 interface, and processing operation, such as decompression of printing image data, image rotation and the like, are finished at the same time, so the transmission efficiency and the throughput of data are greatly improved, and the efficient output of a digital printing machine is realized.

Description

technical field [0001] The invention belongs to the technical field of printing and printing, and in particular relates to a high-speed digital printing processing system based on an embedded processor. Background technique [0002] As the textile printing industry has higher and higher requirements for printing accuracy, flexibility in batch plate making and environmental protection, digital printing technology has gradually replaced traditional printing technology and become the leading technology in the textile printing industry. The rapid growth of digital printing market demand and the rapid development of digital printing industry have higher and higher requirements for digital printing speed, and a processing system with faster data processing capabilities is required to realize data transmission and data processing of digital printing machines. [0003] Most of the current digital printing machines first complete the processing of the printing image on the PC, and th...
