Patent number: 11924568Abstract: In one example, a signal processing device includes first processors, a controller, a first selection section, a second processor, a second selection section, and a first comparison section. The first processors are associated with first signals. The first processors perform a predetermined process on the basis of an associated first signal to generate a second signal. The controller generates a selection control signal. The first selection section selects the first signal to be supplied to a selected first processor on the basis of the selection control signal. The second processor performs the predetermined process on the basis of the selected first signal to generate a third signal. The second selection section selects the second signal generated by the selected first processor. The first comparison section compares the third signal and the second signal selected by the second selection section of the second signals with each other.Type: GrantFiled: July 20, 2020Date of Patent: March 5, 2024Assignee: Sony Semiconductor Solutions CorporationInventor: Masaki Murozuka

Patent number: 11348657Abstract: It is aimed to detect an error of an address abnormality in a memory. An address error detection information generating unit generates address error detection information for detecting an error relating to an access address for a memory. A control part stores the address error detection information generated by the address error detection information generating unit in the memory at a time of write access. An error detecting part compares the address error detection information generated by the address error detection information generating unit with the address error detection information stored in the memory to detect an error at a time of read access.Type: GrantFiled: December 7, 2018Date of Patent: May 31, 2022Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventor: Masaki Murozuka
