面向喷墨打印机的高速数据处理系统

为提高工业喷墨打印机的打印速度，设计基于MPC8548E和Xilinx Virtex 5的高速数据处理系统。MPC8548E处理器通过千兆网从PC端接收经编码的打印图案数据，对其进行解码并通过RapidIO传输给Virtex 5。具有强大实时处理能力的Virtex 5对图案数据进行处理，并将处理后的数据传输给喷头。性能测试结果表明，该系统的数据处理能力可达320 Mb/s，相比国内印花机，在同等条件下其性能提升明显。

High-speed Data Processing System for Inkjet Printer

To increase the printing speed of digital inkjet printer,this paper presents a high-speed data processing system based on MPC8548E and Xilinx Virtex-5.In this system,the MPC8548E processor decodes the received encoded printing design paper data which receives from PC port by Gigabit net and transfers it to Virtex-5 through RapidIO.Virtex-5 has strong ability of real-time processing to transfer the processed data to print heads.Performance test results show that the data processing ability of the system is up to 320 Mb/s,and it is much higher than civil decorating machine under the same condition.
