| Abstract: | In flight test, it is popular that PCM display and control in real-time with industrial computer and PCM decoder. But this product developed is not suitable on small-sized aircraft because of volume and weight. This method was not adopted in this paper, but another outlined with embedded technology of FPGA and DSP. It has been not only described in this paper that decoding of PCM streaming data and the way of data displaying, but also realized the function of PCM decoding and display in real-time. It has been resolved the problem of not suitable mode of PCM displaying on small-sized aircraft. |
