In a data processing device, a processor processes data based on a stored program and a buffer manager accesses the data. The data processing device includes a program memory which stores program codes, the program codes being loaded into the program memory and executed by the processor when processing the data. A shared memory stores one of the program codes and the data. A control unit selectively connects one of the processor and the buffer manager to the shared memory based on a select pattern, wherein the shared memory functions to store the program codes when the select pattern is set in a first condition, and the shared memory functions to store the data when the select pattern is set in a second condition.
