Abstract: A system on chip, semiconductor device, and/or method are provided that include a plurality of masters, an interface, and a semaphore unit. The interface interfaces the plurality of masters with a slave device. The semaphore unit detects requests of the plurality of masters, controlling the salve device, about an access to the interface and assigns a semaphore about each of the plurality of masters by a specific operation unit according to the detection result.

Abstract: An electronic system may include one or more units of processing circuitry configured to implement a main intellectual property (IP), a checker IP, and an error detection circuit. The main IP includes a first data path and a first control signal path. The checker IP includes a second control signal path. The error detection circuit is configured to detect an error of data by performing error correction code (ECC) decoding of output data that is output by the main IP to the error detection circuit through the first data path, and detect an error of a control signal based on a first signal that is output by the main IP to the error detection circuit through the first control signal path, and a second signal that is output by the checker IP to the error detection circuit through the second control signal path.

Abstract: A universal serial bus (USB) communication system includes a USB host that divides one data stream into first through (n)th sub-data streams and transmits the first through (n)th sub-data streams via first through (n)th USB host channels, respectively, a USB device that receives the first through (n)th sub-data streams via first through (n)th USB device channels, respectively and restores the data stream by combining the first through (n)th sub-data streams, and first through (n)th cables that are connected to the first through (n)th USB host channels via first through (n)th USB host ports and connected to the first through (n)th USB device channels via first through (n)th USB device ports. Here, the first through (n)th cables connect the first through (n)th USB host channels to the first through (n)th USB device channels, respectively.
