摘要:
A method and apparatus for processing data in a heterogeneous multi-core environment, capable of reducing data processing time by storing frames not having redundant data only among input frames in a shared memory. The apparatus compares a second frame with a first frame having a time difference with respect to a first frame, thereby determining identity between the first frame and the second frame. The apparatus stores address information related to the first frame or stores the second frame according to the determination result, thereby reducing quantity of data to be updated.
摘要:
Provided are a data processing apparatus and a method of controlling the data processing apparatus. The data processing apparatus may select a single stream processor from a plurality of stream processors based on stream processor status information, and input data into the selected stream processor. The stream processor status information may include first status information of a processor core and second status information of at least one internal memory.
摘要:
Provided is an image processing apparatus. When a plurality of images acquired by photographing different directions is input, a region search unit of the image processing apparatus may search for an overlapping region within the plurality of images. An outlier removal unit may remove an outlier within the retrieved overlapping region.
摘要:
A multiprocessor system and a migration method of the multiprocessor system are provided. The multiprocessor system may process dynamic data and static data of a task to be operated in another memory or another processor without converting pointers, in a distributed memory environment and in a multiprocessor environment having a local memory, so that dynamic task migration may be realized.
摘要:
Provided is a method and system for dynamically parallelizing an application program. Specifically, provided is a method and system having multi-core control that may verify a number of available threads according to an application program and dynamically parallelize data based on the verified number of available threads. The method and system for dynamically parallelizing the application program may divide a data block to be processed according to the application program based on a relevant data characteristic and dynamically map the threads to division blocks, and thereby enhance a system performance.
摘要:
Disclosed is a scratch pad memory management device and a method thereof. The scratch pad memory management device divides a scratch pad memory into a plurality of unit blocks, maintains a memory allocation table corresponding to indices of the plurality of unit blocks in a main memory, and manages the scratch pad memory.
摘要:
A memory access address translating apparatus and method may each classify pixels included in an input image into a plurality of tiles, and may generate a new memory for each of the successive tiles to enable the successive tiles, among a plurality of tiles, to be stored in different banks.
摘要:
Provided is a hardware acceleration apparatus, method and computer-readable medium efficiently processing multi-core synchronization. A processor core that fails to acquire a lock variable may be switched to a low power sleep mode and a waste of power may be reduced. Additionally, when a lock variable is returned, a wakeup signal may be transmitted to a processor core operated in the low power sleep mode, and the processor core may be activated.
摘要:
Provided is a method and apparatus for measuring a progress or a performance of an application program in a computing environment using a micro-architecture. An apparatus for thread progress tracking may select a thread included in an application program, may determine, based on a predetermined criterion, whether an execution scheme for at least one instruction included in the thread corresponds to an effective execution scheme in which an execution time is uniform or a non-effective execution scheme in which a delayed cycle is included and the execution time is non-uniform, and may generate an effective progress index (EPI) by accumulating an execution time of an instruction executed by the effective execution scheme other than an instruction executed by the non-effective execution scheme.
摘要:
A signal processing apparatus and method providing a 3-dimensional (3D) sound effect may determine a mask related to an ambience of an input signal, separate the input signal into a primary signal and an ambience signal using the mask, decorrelate the ambience signal, and sum the decorrelated ambience signal and the primary signal, accordingly generating an output signal to which a sound effect is applied.
