Abstract: An ECU monitoring system includes: an ECU that includes an input interface unit, a computer unit, and an output interface unit; a storage unit that stores a normal input signal and a normal output signal; a comparing unit that calculates a compared difference by comparing the current input signal with a previous input signal stored in the storage unit, and outputs an alarming signal showing the current input signal is abnormal, when the compared difference is out of a predetermined range; and a circulator that receives the output signal, provides the output signal when the output signal is a normal output signal, and provides a normal output signal to the output interface unit, instead of the output signal outputted from the computer in response to the abnormal input signal, when receiving the alarming signal from the comparing unit.

Abstract: Provided are a system and method for managing a neuromorphic memory. The system includes a memory having a multi-dimensional lattice structure, a prescience estimator (PSE) configured to separately estimate memory use of two or more data sets and determine a sequence of inputting the two or more data sets to the memory, and a prescience manager (PSM) configured to allocate memory regions in which the two or more data sets will be stored according to estimation results of the PSE, store the data sets, and perform learning and inference.

Abstract: An audio system based on an in-vehicle optical network and a broadcasting method thereof are provided. The audio system according to an exemplary embodiment includes: a multi-channel router which is connected to an in-vehicle optical network to receive a multi-channel audio signal from audio signals received from the optical network; and a plurality of speakers which are connected to the multi-channel router to receive the multi-channel audio signal through the multi-channel router. Accordingly, the speakers can operate by interworking with a network even when they have no function as network devices.
