An electronic apparatus that writes encrypted data includes a first memory; a second memory configured to update encryption information including address information indicating a write location on the first memory and a parameter for use in encryption when data is encrypted and written to the first memory, and store the updated encryption information; an encryption and decryption unit configured to encrypt the data, based on the encryption information; and a processor configured to control the encrypted data to be written to the first memory, thereby increasing a safety level.

Data encryption method and electronic apparatus performing data encryption method

A computing system is disclosed. The computing system according to one embodiment of the present disclosure comprises: a memory device for storing an application program; a processor for executing a loader for loading data of the application program into a memory space allocated for execution of the application program; a local memory having a width corresponding to the size of a register of the processor; and a constant memory having a width smaller than that of the local memory, wherein, according to the size of constant data included in the application program, the processor loads the constant data into one of the local memory and the constant memory.

Computing system, and driving method and compiling method thereof

A sound discriminating method comprises sensing a sound signal; changing the sensed sound signal into an electrical signal; and determining whether the electrical signal is a predetermined sound by analyzing the electrical signal.

Method for determining sound and device therefor

A method of generating a multi-channel audio signal includes: representing locations of a plurality of speakers as a plurality of polygons whose vertices are located at locations of corresponding speakers; acquiring a location of an object sound; calculating distances between the plurality of polygons and the location of the object sound; selecting one of the plurality of polygons on the basis of the calculated distances; and generating a multi-channel audio signal that corresponds to speakers corresponding to the selected polygon by mapping the object sound to the speakers corresponding to the selected polygon.

Method of generating multi-channel audio signal and apparatus for carrying out same

A method of performing quadrature mirror filter (QMF) synthesis filtering includes recording new samples corresponding to a current time slot at positions of samples to be discarded in a first array that includes modulated QMF sub-band samples. The method further includes extracting samples from the first array to remove aliasing between adjacent sub-bands, determining filter coefficients corresponding to the extracted samples by using modulo operation, and synthesizing a time domain sample where aliasing is removed by using the extracted samples and the filter coefficients.

Method and apparatus for quadrature mirror filtering

A multi-decoding method, according to the present invention, comprises the steps of: receiving a plurality of bitstreams, dividing decoding modules for decoding the plurality of bitstreams according to a data amount of an instruction cache, and cross-decoding the plurality of bitstreams using each of the divided decoding modules.

Multi-decoding method and multi-decoder for performing same

A method of processing a sound signal is disclosed. The method of processing a sound signal includes receiving a sound signal from the outside of a device, converting the sound signal into a first frequency domain signal, determining whether or not the sound signal is a voice signal using the first frequency domain signal acquired through the conversion, converting the first frequency domain signal into a second frequency domain signal based on the determination, and recognizing the sound signal using the second frequency domain signal acquired through the conversion.
