PROBLEM TO BE SOLVED: To reduce power consumption more effectively in an information processing device with a radio communication function.SOLUTION: An information processing device 1 comprises a communication module 13, a first CPU 11, a second CPU 12, and UARTIF 11b, 12b, 12c, 13a. The communication module wirelessly communicates with an external apparatus. The first CPU 11 is able to switch between a sleep state in which the execution pf processing is restricted and a normal state of executing processing. The second CPU 12 is connected between the communication module 13 and the first CPU 11, able to operate at lower power consumption than the first CPU 11, and able to transfer data by direct memory access. The UARTIF 11b, 12b, 12c, 13a are comprised in each of the communication module 13, the first CPU 11, and the second CPU 12, and input and output data in the same data format.SELECTED DRAWING: Figure 1 |
