SIGNAL PROCESSING SYSTEM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a signal processing system capable of continuing signal processing even when abnormality due to an input signal or control data occurs.SOLUTION: In a signal processor 10, two signal processing means, that is, an operation system (FPGA13) which executes the same signal processing to an input acoustic signal and a standby system (signal processing module 12A to be executed on a CPU 12) operate. The standby system executes signal processing with a higher processing capacity than the operation system. When detecting a signal S31 indicating an error from the operation system, a determination part 41 of a selection part 22 controls selection means 42 to select an output signal S35 from the standby system instead of an output signal S34 from the standby system, and switches the operation system to the standby system.
