Abstract
Official abstract text for this publication.
An error detection method is to detect an error in a program to control hardware, which executes predetermined processing, via a register. The error detection method includes: outputting a signal indicating whether the predetermined processing is in execution; detecting that a change is made in a register value in the register, which register value is related to control of the predetermined processing, and outputting a detection signal; and detecting an error when it is detected, based on the signal indicating whether the predetermined processing is in execution and on the detection signal, that the change is made in the register value while the predetermined processing is in execution.
First claim
Opening claim text (preview).
What is claimed is: 1. An error detection method of detecting an error in a program that controls hardware, the hardware executing predetermined processing via a register, the error detection method comprising: outputting a signal indicating whether the predetermined processing is in execution; detecting that a change is made in a register value in the register, which accepts control from the program to control the predetermined processing, the register value controlling a start…
