The Design of Embedded Motion Controller Based on DSP and Development of Driver under Linux
In this paper, in order to solve the problem of PC-based CNC system, such as instability high cost, large volume so and on , an embedded motion controller based on S3C2440 system bus is designed by using S3C2440 microprocessor and PCL6045B special DSP chip. Hardware interface circuit and address mapping between ARM and PCL6045B are introduced in detail, and some interface functions of the motion controller base on multi-tasking Linux operating system is designed. At last, the driver development and driver debugging of PCL6045B motion control chip under Linux are focused on. The result indicates that this controller can not only improve the real-time performance and reliability of system under the support of Linux, but also reduce the cost greatly.
