Embedded ARM processor FPGA technology in star sensor

An ARM(advanced RISC machine)embedded FPGA(field programmable gate arrays)chip - EPXA10 was introduced. A research of image acquisition and star position locating based on this technology were done and the accomplishment was achieved. The driving of the CMOS(complementary metal-oxide-semiconductor transistor) image sensor and the pre-processing of the digital image were accomplished in FPGA part of the EPXA10. The star position locating algorithm was achieved in ARM part of the EPXA10. The programs of serial port communication and the image display were realized by Visual C+ + language. The clear picture taken by the CMOS image sensor and the locating result were presented. By comparing the locating results of ARM and PC(personal computer),the result was accurate. The processing speed of the whole system is increased and the complexity, volume and power consumption of the circuit are reduced by adopting an ARM Embedded FPGA.
