Embodiment Construction

[0014] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0015] The high-speed digital printing method based on the multi-core processor and DMA technology of the present invention is realized on the digital printing system, and the structure of the digital printing system is as follows: figure 1 As shown, it includes multi-core processor, memory, system bus, DMAC, nozzle and hard disk; where: DMAC, multi-core processor and memory are connected through the system bus, and DMAC is connected to the nozzle and hard disk respectively.

[0016] In the multi-core processor, one of the cores is dedicated to processing print commands, and the other cores are used for complex processing such as image decompression and rotation. Dedicated to one core to process print commands can quickly and efficiently process print commands, while using multi-core processors to process images can greatly speed up image p...

Abstract

The invention discloses a high-speed digital printing method based on a multi-core processor and the DMA technology. The problem that an existing digital printing machine still cannot carry out real-time processing on a large number of images due to the limitations of the PC processor performance and parallel interface data transmission is solved. Firstly, a multi-core processor is used for quickening processing on printing commands and printing images, then the DMA technology is used for achieving the input / output operation mode that automatic in-batch data exchanging is carried out between a high-speed peripheral device and a main memory so as to reduce CPU interference to the greatest extent, the efficiency of a whole computer system is greatly improved, finally the RAID technology is used for improving the access speed of a hard disk, and therefore the efficiency of a whole digital printing system is promoted.

Description

technical field [0001] The invention belongs to the technical field of digital printing, and in particular relates to a high-speed digital printing method based on a multi-core processor and DMA technology. Background technique [0002] China is a big country in the textile industry, and textiles account for a large part of China's export products. Printing and dyeing is an effective means to enrich the variety of textile designs and improve product grades. It is recognized as a high value-added industry in the textile industry. Printing and dyeing can bring higher value to textiles. Textiles after printing and dyeing can not only be used as daily necessities, but also become A kind of handicraft. As a handicraft, the value of textiles is further enhanced. However, there are many problems in the traditional textile industry. For example, the traditional textile printing and dyeing industry is a typical industry with high energy consumption, high noise and high pollution. ...
