Abstract: A method for applying error correction code (ECC) to a memory performed by an apparatus for applying ECC to a memory in an artificial neural network-based system semiconductor, includes dividing memory cells into a plurality of groups of memory cell arrays corresponding to first to n-th frames based on word lines, wherein n is a natural number greater than or equal to 2, performing an ECC write or read operation by applying ECC to a memory cell array of a group corresponding to each of the first to n-th frames, and performing a general write or read operation without applying ECC to the memory cell array of the remaining groups excluding the group corresponding to each of the first to n-th frames.

Abstract: The present invention enables efficient decoding by using DR mapping information between a base layer and an enhancement layer in various manners in an HDR decoder considering backward compatibility.

Abstract: A low noise amplifier (LNA) gain control method and a broadcast receiving device performing the same are disclosed. The method includes determining a LNA gain control based on a power measurement value of a received broadcast signal, confirming whether the received broadcast signal corresponds to a service channel period, stopping the LNA gain control when the received broadcast signal corresponds to the service channel period, and performing the LNA gain control when the received broadcast signal does not correspond to the service channel period.

Abstract: Disclosed is a method for processing, by a rear view camera image processing apparatus operated by at least one processor, an original rear image collected by a rear view camera, in which when the rear view camera collects an original rear image, the original rear image is processed through each of a first path and a second path, and an output image generated through the first path is displayed to a display apparatus, and a reduced rear image generated through the second path is temporarily stored. The effectiveness of the output image generated through the first path is judged, and when the output image is not effective, the temporarily stored reduced rear image is generated as a rear output image and delivered to the display apparatus.

A system on chip (SoC) comprises a plurality of central processing units (CPUs) for executing at least one operating system, a graphics processing unit (GPU) that is connected to each of the plurality of CPUs via a bus interface and communicates with each of the plurality of CPUs, and at least one state monitoring device that is selectively connected to at least one CPU among the plurality of CPUs and transmits execution state information of at least one operating system executed in the connected CPU to the GPU. The GPU is shared by at least one operating system and controls a sharing operation by the at least one operating system based on the execution state information of the at least one operating system.

Abstract: A system-on-chip (SoC) for operating a plurality of different central processing units and a method for operating the same are provided. The SoC includes a plurality of central processing units (CPUs) that execute respective software programs independently of each other, a bus interconnector for connecting the plurality of CPUs, and at least one access control device that is connected to the bus interconnector and controls each access to a physical resource shared by the plurality of CPUs via the bus interconnector, for each CPU.

Abstract: Disclosed is a method for suppressing an inter-carrier interference and noise signal, and an orthogonal frequency division multiplexing receiver for performing the same. Here, a method for an orthogonal frequency division multiplex (OFDM) receiver to suppress an inter-carrier interference and noise signal by using a symbol interference free interval without inter-symbol interference (ISI) in a guard interval (GI) includes: performing a weighting operation between sample data of the symbol interference free interval and sample data of the effective symbol interval by using a signal-to-noise ratio (SNR) of the symbol interference free interval and an SNR of an effective symbol interval corresponding to the symbol interference free interval; and performing a fast Fourier transform (FFT) on FFT input data configured by including the weighting-operated sample data into the effective symbol interval.

Abstract: A media processing device uses an external storage device. The media processing device includes a storage device access module, an information source, a program memory, a system memory, a signal processor, a user interface and a system controller. The system controller accesses the external storage device, reads file information, and constructs contents to be displayed. When the system controller receives a command to select a media file, the system controller accesses the external storage device, searches for the selected media file, reads data of the searched media file, copies the read data, and provides the copied data to be decoded. When the system controller receives a commend to encode a signal, the system controller controls the signal processor to encode the input signal into media data, constructs a media file from the encoded media data, positions the media file, and copies the constructed media file when the external storage device is accessible through the storage device access module.
