Title Design on control system based on AT91RM9200
Abstract
With industrial development and progress, embedded systems have become the main force of industrial systems and civilian systems. Embedded systems continue to develop, gradually replace PC as the mainstream of post-PC era.
In this paper, the design and debugging of the control circuit based on AT91RM9200 and the cyclone III FPGA are completed. ARM is responsible for overall control and data processing, and FPGA is due to generate a variety of timing control, FPGA is connected with ARM via the bus, as a peripheral device of the ARM. In the paper, circuit designs of the AT91RM9200 system and FPGA-based system are introduced, the designs of the driver of each module , the boot loader, interrupt handler and the main program are also introduced,at last the test process and results are given, which show that this system meets the design functional requirements.
