Title:
DIGITAL SIGNAL PROCESSING CIRCUIT
Document Type and Number:
Japanese Patent JP2020021359
Kind Code:
A
Abstract:
To provide a digital signal processing circuit capable of improving response speed of a processor, capable of suppressing malfunction due to noise, and capable of reducing constraints on kinds of signals capable of exerting these effects.SOLUTION: Whether the input voltage is a signal or not is determined, and a task is executed. The task comprises a first part present before a hold point or before it, and a second part present after the hold point. The hold point is present before a point where a malfunction occurs when the input voltage is an incorrect input. Interlocked with inputting of edge of the input voltage, execution of the first part is started, and a result of the execution of the first part is held when the execution of the first part is completed. When it is determined that the input voltage satisfies a condition under a state where it is not determined that the input voltage is the signal, at least one of that the execution of the first part is stopped and that the result of the execution of the first part is reset is issued.SELECTED DRAWING: Figure 1
