Design of the embedded system uses the system architecture of double CPU (ARM+DSP), making full use of the control capability of ARM and the processing capability of DSP. The architecture makes the work separated more clearly and the function more strong in the system. By transplanting excellent Real Time Operating System, Linux, the equipments are provided with an effective, perfect, stable, reliable software platform, using QT which is the most popular graphics designing tool in Linux operating system to design an intelligentized man-machine interface. An embedded EMAT system based on ARM and DSP is designed successfully. The Electro-magnetic Acoustic Transducer (EMAT) system adopts advanced and reasonable hardware framework of superstratum plus substrate computers, embeds Linux operating system and an intelligentized man-machine interface.
