  • Patent number: 11455248
    Abstract: A semiconductor device performs a software lock-step. The semiconductor device includes a first circuit group including a first Intellectual Property (IP) to be operated in a first address space, a first bus, and a first memory, a second circuit group including a second IP to be operated in a second address space, a second bus, and a second memory, a third bus connectable to a third memory, and a transfer control circuit coupled to the first to third buses. when the software lock-step is performed, the second circuit group converts an access address from the second IP to the second memory such that an address assigned to the second memory in the second address space is a same as an address assigned to the first memory in the first address space.

  • Publication number: 20220295137
    Abstract: A cable may be satisfactorily used that has a specific function such as a register that holds specification data and a current consumption unit such as an element for adjusting signal quality. The cable is connected between a first electronic device and a second electronic device. A determination unit determines whether or not the first electronic device is a compatible electronic device. A control unit performs control to operate in a compatible mode when the first electronic device is a compatible electronic device and operate in a non-compatible mode when the first electronic device is not a compatible electronic device on the basis of the determination result by the determination unit. Furthermore, an electronic device is connected to an external device via the cable. The determination unit determines whether or not the cable is a compatible cable.

  • Patent number: 11394797
    Abstract: A first communication section of an information processing device performs communication in a first segment of an IP network. A second communication section performs communication with other information processing devices via a non-IP wire interface. A proxy processing section generates a wire control command that is a control command using the wire interface on the basis of an IP control command that is a control command received from a first controller belonging to the first segment. The proxy processing section executes proxy processing on the basis of the wire control command by using the second communication section. The sharing processing section shares related information relating to a proxy control by the proxy processing section with a second information processing device belonging to a second segment.
