Debug Of Integrated And Embedded NMR Spectrometer And Design Of Device Drivers

This paper describes an ARM-based integrated nuclear magnetic resonance spectrometer (NMRS) which is designed to resolve problems that the previous NMRS encounters, such as complicated structure, too big size and high price. This new system consists of digital frequency source, digital receiver, gradient waveform generator, impulse train control module and PC. Also, one kind of data exchange system is introduced for the integrated nuclear magnetic resonance spectrometer to solve other problems of the previous NMRS. Furthermore, the transplantation of embedded operation system of ARM-based ( Advanced RISC Machines ) micro processor, debug process and its result through the combination of ADS debugger and data exchange of integrated NMRS, as well as the design of device drivers are included. This papers ends with the discussion on the research & fabrication process and the test result.This paper mainly covers the following contents:1. Introductions of principles of NMR and NMR imaging as well as the structure of NMR imaging system;2. Introductions of concept of ARM Linux and transplantation of ARM Linux operation system;3. Detailed description of one kind of data exchange method of integrated NMRS;4. Detailed description of debug tools used, debug process and test result through the combination of ADS debugger and data exchange of integrated NMRS, as well as the design of device drivers; and,5. Summary and analysis of the whole debug process and the test result, as well as the expectations on the new system.
