The design of embedded image teaching systems based on ARM technology

With the continuous development of multimedia and speech teaching laboratory in colleges and universities, and the application of digital processing technology, digital voice teaching equipment is attracting more and more attention from domestic universities and instrument manufacturers. Based on the core technology of ARM and DSP dual core technology, the theoretical analysis of digital language learning system is carried out, and the student terminal circuit and teaching software system are designed in detail, and the function and technical index of the whole system are tested. The test results show that the digital speech learning system constructed by the student terminal controlled by ARM and DSP binuclear is fully satisfied with the actual language teaching requirements.
