摘　　要：针对电脑横机选针器控制的实时性要求,给出一种结合ARM模块和FPGA二级控制的设计方案。ARM模块通过对花样文件进行解析后生成控制数据,并发送给FPGA;FPGA采用双缓冲结构对选针数据进行缓存,并设计一个流水线执行结构实现对选针器的实时控制。应用结果证明,该方法充分发挥了ARM系统快速运算和FPGA并行处理的优势,双缓冲结构的存储器设计和流水线执行方式,有效提高了数据吞吐率,实现了高速编织时选针器的可靠控制。For the real-time requirements of needle selection control of computerized flat knitting machine, the paper presents a new kind of secondary control design approach combined with ARM module and FPGA. The ARM module software analyzes pattern files to get control data and then transfers them to FPGA, and the FPGA caches control data in a double-buffered-memory. In addition, a pipeline execution structure is designed to achieve the re- M-time controllability of the needle selection. The results show that this method can take full advantage of fast cal- culation of the ARM module and the parallel processing characteristic of FPGA; and the double-buffer-memory and the pipeline structure can effectively improve the data throughput rate, which will make needle selection stable at high speed knitting.
