Abstract： |
The invention relates to the area of the electroacoustic technique, especially the technique area for processing the digital audio frequency in multiple format modes. The character of the invention are as follows: the player includes the program storage units shared by the program data and the program algorithm, the controller interlinked to the program storage units in sequence and the digital signal processor. Based on the structure features of the player, the invention has designed the method for loading, updating and adding the algorithm. The invention eliminates the costly algorithm storage, uses the storage reasonably so as to make users utilizes the player expediently. Meanwhile, the size of the print circuit board is reduced so as to reduce the power dissipation as well as the cost of the player. |
