Embedded NC System Based on ARM and DSP

Embedded NC system integrates essential modules into its core by means of "acting according to actual circumstances", which can overcome the drawbacks in the system volume and power consumption of the traditional NC system based on IPC structure, cut down the costs and enhance the system\´s performance. The paper provides the embedded NC system with the architecture of ARM and DSP, in which the ARM takes charge of the G code input, compiling and interpretation, the simulation display, the user\´s interface and the network interface etc, while the DSP is mainly in charge of real-time tasks such as interpolation computation and path control. Also the hardware and software architectures are introduced in the paper. NC system built on the embedded technology can reduce the system hardware scale, facilitate application development, cut down the costs and promote the system\´s reliability and real-time performance
