| 摘 要： | 在三星S3C6410硬件平台上,开发了基于Linux3.0.1内核的双口RAM驱动程序。双口RAM驱动程序遵循"机制"与"策略"相分离的设计思想,实现了对双口RAM随意读、写操作的机制。根据该操作机制和大直径提花圆纬机的控制特点,设计了应用程序对双口RAM的访问策略。实验结果表明,大圆机控制系统启动时能加载双口RAM驱动程序并正确识别双口RAM,大圆机控制系统能通过双口RAM实现上下位机的参数传递。

| Abstract: | This paper develops dual-port RAM driver based on Linus3. 0. 1 on Samsung S3C6410 hardware platform. Dual-port RAM driver follows the design idea of separation between ＂mechanism＂ and ＂strategy＂ and realizes the mechanism of random reading and writing operations of dual-port RAM. This paper designs access strategy of application program for dual-port RAM according to this operating system and control features of large diameter jacquard circular knitting machine. The experimental result shows that the control system of circular machine can load dual-port RAM driver and correctly identify dual-port RAM when starting; it can realize parameter transfer of upper and lower computers through dual-port RAM. |
