The Design Of Digital Storage Oscilloscope And The Realization Of Control System Based On ARM

As one of the most common equipments the engineers use in research and development,the oscilloscope has been widely used in project measurements.The Digital Storage Oscilloscope(DSO)has become one of the most fast-developed equipments because of its proper characteristics.With the enhancing requirements on speed,precision and intelligentization,the 32-bit high-powered ARM microprocessor has become the best choice as a main CPU in complicated systems instead of the 8-bit singlechip.According to the schemes of traditional DSOs and requirement details of this project,the ARM+FPGA scheme is presented.The ARM microprocessor makes the control simple as well as the programming because of its strong control ability and flexible connectors.The design and realization scheme is highlighted in the paper.In this typical embedded system,an ARM9 microprocessor S3C2410 of SAMSUNG is employed withμCOS-Ⅱreal-time operation system running upon it.The software design is based on ADS1.2 with JTAG debugger.Practical testing verifed that the operation system can run successfully,the system can respond to keyboard's real-time input and show precise image of signals in its effectual bandwidth. Rear part of the paper gives testing procedure and results,along with possible improvements being discussed.
