<p>PURPOSE: A data processing system and an operation method thereof are provided to reduce power consumption by increase of a buffer size in case there is no activity of a user. CONSTITUTION: An audio processing device includes a plurality of buffers for storing data and data I/O(Input/Output) units for outputting the stored data. In case an interrupt signal is generated according to transmission complete of data stored in a first buffer, a DMA(Direct Memory Access) controller transmits data stored in a second buffer. The DMA controller changes each buffer to long buffers by increasing the size of each buffer(330,340). [Reference numerals] (AA) Generation of an interrupt signal; (BB) Current location</p> |
