Research and development of an embedded numerical control system

This paper Puts forward a new scheme of Embedded Numerical Control System based on ARM and DSP, which is at the base of research on traditional numerical control system and embedded technology. And the paper also describes the development of hardware and software platform. All the development and realization are based on the idea of module design. The embedded numerical control system, using ARM and DSP to construct the main control platform, realizes the real-time operation of system and improves the stability and reliability with the modular designing ideas of hardware and software and with the support of embedded real-time operating system (uc/os-II). And the system could realize the multi-network supporting, which is also accord with the development of modularization, flexibility and latticing of numerical control system.
