摘要
提出一种基于OMAP-L138双核处理器的嵌入式运动控制器的设计方法。利用OMAP-L138的ARM核实现人机界面、数控代码编译等功能,DSP核实现插补及产生脉冲、控制电机运转。该控制器采用双CPU架构及片内内存共享数据的设计方法,能够更好地满足嵌入式运动控制器对实时性、控制精度及功耗的要求。
The design method of embedded motion controller based on dual-core OMAP-L138 processor is in- troduced. The human-machine interface and NC code compilation are achieved by OMAP-L138＇s ARM core. The interpolation algorithm is achieved by DSP core, which generate pulses to control the motor running. The dual CPU architecture and on-chip memory to share data are adopted in the embedded motion controller. This is better able to meet the requirements of the embedded motion controller for r^al-lim~ onntral ;~; A
