With the ever-changing times, technological progress, media transformation, and innovation, the soil for the growth of digital media art has been cultivated. The rapid development of the mobile Internet combines multimedia communications such as pictures, text, audio, video, and data, which greatly enriches people’s life experience. Embedded systems have strong processing capabilities, small size, and convenient use. In recent years, they have become the mainstream of multimedia research. Therefore, this paper proposes a research on the design of an embedded system intelligent platform based on digital multimedia artistic design. This paper adopts the literature research method to study the development and evolution of digital multimedia and the characteristics and applications of embedded systems and other related theoretical research and design an embedded system intelligent platform based on the artistic design of digital multimedia, from software and hardware design and application The platform design research is carried out in three aspects of the program, and the effect comparison of system’s scheduling test, real-time test, peak signal-to-noise ratio test, and digital multimedia art design is analyzed. The experimental results show that when the pixel values are the same (both are 6), the signal-to-noise ratio of this method reaches 48.5, which is higher than the output value of other method platforms, and the system setting performance is better.
