In a video audio processing device, a signal processing block (11, 12) includes an instruction memory (111, 121) and performs signal processing in accordance with a program loaded into the instruction memory. A main storage section (20) has a self-refresh function and is accessible from the signal processing block. An auxiliary storage section (30) stores the program for making the signal processing block perform the signal processing. Upon receipt of a standby instruction, a control section (15) performs control in such a manner as to transfer the program from the auxiliary storage section to the main storage section, and set self-refresh in the main storage section, and upon receipt of a return instruction, performs control in such a manner as to cancel the self-refresh in the main storage section, load the program from the main storage section to the instruction memory in the signal processing block, and activate the signal processing block.
