To solve the problem which current research of RTCP function is limited to high-grade CNC system. Based on limited computational resources of the embedded CNC system, analyzes and modeling calculates RTCP function of CA double swing structure, and points out the offset distance is only related to the chord length corresponding to the arc length that the rotating radius crosses, and obtains the calculation formula of compensation. Finally, gives the implementing flow chart of the RTCP algorithm for low-cost embedded CNC system.

In order to realize high speed, high precision, high reliability, miniaturization performance of the CNC (Computer numerical control) system, this paper proposed a hardware platform of embedded CNC system based on OMAPL138 and FPGA. OMAPL138 is a SOC using C6748 DSP kernel and ARM9 kernel dual-core structure, the kernel frequency can achieve up to 375/456 MHz. ARM kernel of the CNC system which runs the Linux operation system is responsible for task management, DSP kernel is in charge of real-time interpolation and look-ahead algorithm, and FPGA module generates pulses to control the movement of the servo motor. Firstly, the overall hardware architecture of the embedded CNC system was designed. Meanwhile the hardware circuit design of CPU core module based on OMAPL138, human-computer interaction module, EMIFA bus interface of the FPGA core module were emphasized in detail, and also the serial port, Ethernet, USB communication interface module were introduced. A serial test experiments have been conducted and the results have shown that this embedded CNC system is powerful and stable.
