With the continuous promotion of ARM technology, and now people39。s daily life, the application of embedded systems which have already infiltrated. Can be said that embedded systems are now widely used in military, industrial, mercial, medical, personal and family aspects, and it is fast developing. Especially the electronic digital products, and its replacement quickly, which from the initial discrete ponents to the current integrated chip, and the product is smaller and smaller, but exhibited by the function is more powerful. This design uses DE2 development board as the main board, and presented digital music albums which based on the Nios II. Mainly realized on the SD card through the audio and image files stored in a read operation, after controlling the construction of the Nios processor, the audio information is transmitted to the audio module player, the picture information transmitted to the TFT LCD display, while using the touch operation of the whole Function. Hardware is mainly responsible for the construction pletion of the Nios processor, the audio module and the LCD part of the welding. Software ponent is mainly responsible for SD card, TFT LCD, touch the bottom of the chip, the audio module drivers and write the entire application. Through the pletion of hardware and software, finally pleted design that the album of electronic music which based on the SOPC.
