An external intrinsic interface. A processor may include a core including a plurality of functional units, an intrinsic module located outside the core, and an interface module to perform relaying between the intrinsic module and a functional unit, among the plurality of functional units.

External intrinsic interface

An apparatus and method for processing a primitive in a three-dimensional (3D) graphics rendering system is provided. The primitive processing apparatus may discard a primitive or store the primitive in a memory, depending on whether a sampling point overlapping the primitive is present among sampling points in a pixel area.

Apparatus and method for processing primitive in three-dimensional (3D) graphics rendering system

A rendering system and method. The rendering system may perform rendering using a rendering context stored in an internal memory. When a rendering context to be used is not available in the internal memory, the rendering system may load the rendering context to be used from an external memory into the internal memory. When an insufficient amount of storage space is available in the internal memory, storage space may be secured by selectively deleting a rendering context from the internal memory, and a requested rendering context stored in the external memory may be loaded into the internal memory.

Rendering system and method

Provided is a method and apparatus for ray tracing. A traversal unit to process an input ray to be input among a plurality of traversal units may be determined based on age of each of the plurality of traversal units. Age of the determined traversal unit may be determined based on age of each of rays that are processed by the traversal unit.

Method and apparatus for ray tracing

A non-blocking texture cache memory for a texture mapping pipeline and an operation method of the non-blocking texture cache memory may include: a retry buffer configured to temporarily store result data according to a hit pipeline or a miss pipeline; a retry buffer lookup unit configured to look up the retry buffer in response to a texture request transferred from a processor; a verification unit configured to verify whether result data corresponding to the texture request is stored in the retry buffer as the lookup result; and an output control unit configured to output the stored result data to the processor when the result data corresponding to the texture request is stored as the verification result.

A method for tile-based rendering may include verifying a size of a memory available in an apparatus for rendering, and determining a number of buffers required for performing a rendering based on graphics data input, and may further include determining a size of a tile to be used for performing the rendering based on the determined number of buffers and the size of the memory available.

Method and apparatus for tile-based rendering

Disclosed is a method and apparatus for performing tile-based rendering. A sequence of tiles to be processed may be determined based on a locality among the tiles. A tile dispatch unit selects a subsequent tile to be dispatched, based on the determined sequence. The tile dispatch unit may check whether an idle fragment processor exists among the plurality of fragment processors, and may dynamically dispatch the selected tile to an idle fragment processor

Method and apparatus for tile based rendering using tile-to-tile locality

A method for processing a three-dimensional (3D) image of a ray tracing scheme may be performed by an image processing apparatus by verifying whether local index information matching intersection point information of a ray is present within a prefetch table when intersection point information is received, and by transferring, to a shader, rendering information stored in a local memory based on the local index information, when the local index information matching the intersection point information is present.

Apparatus and method for image processing

An apparatus and method for non-blocking execution of a static scheduled processor, the apparatus including a processor to process at least one operation using transferred input data, and an input buffer used to transfer the input data to the processor, and store a result of processing the at least one operation, wherein the processor may include at least one functional unit (FU) to execute the at least one operation, and the at least one FU may process the transferred input data using at least one of a regular latency operation and an irregular latency operation.

A compilation apparatus may select a data format showing an optimum performance when a binary code is executed, from among a plurality of data formats supported by an execution apparatus used to execute a binary code, and may generate a binary code that uses the selected data format. The execution apparatus may execute a binary code provided by the compilation apparatus.

Method and apparatus for dynamic data configuration

A processor for processing stream data at a high speed is provided. The processor may include a functional unit to perform an operation on the stream data, an input interface module to perform relaying between the functional unit and an external data producer module that is used to input the stream data to the processor, and an output interface module to perform relaying between the functional unit and an external data consumer module that is used to receive an input of result data regarding a result of the operation performed by the functional unit.

Processor and system for processing stream data at high speed

A method and apparatus for providing shared caches. A cache memory system may be operated in a first mode or a second mode. When the cache memory system is operated in the first mode, a first cache and a second cache of the cache memory system may be operated independently. When the cache memory system is operated in the second mode, the first cache and the second cache may be shared. In the second mode, at least one bit may overlap tag bits and set index bits among bits of a memory address.

Method and apparatus for providing shared caches
