摘要： A ray tracing core comprising a ray generation unit and a plurality of T&I (Traversal & Intersection) units with MIMD (Multiple Instruction stream Multiple Data stream) architecture is disclosed. The ray generation unit generates at least one eye ray based on an eye ray generation information. The eye ray generation information includes a screen coordinate value. Each of the plurality of T&I units receives the at least one eye ray and checks whether there exists a triangle intersected with the received at least one eye ray. The triangle configures a space.

摘要： A ray tracing core comprises a ray tracing unit (RTU), a control unit, and a tree build unit (TBU). The ray tracing unit performs ray tracing based on a spatial partitioning structure. The control unit calculates the degree of complexity of the spatial partitioning structure by monitoring the load state of the ray tracing unit. The tree build unit builds the spatial partitioning structure having the degree of complexity which is calculated. The load state is determined based on a frame rate which is processed in the pertinent unit. The spatial partitioning structure applies a K-dimensional tree. For example, the degree of complexity can be modified according to either the maximum primitive number of a leaf node with respect to a K-dimensional tree structure or a tree depth.

摘要： A misinput avoidance method of a mobile terminal may be implemented to prevent a misinput caused by contacting unintended keys around the target key. A misinput avoidance method of a mobile terminal according to the present invention includes detecting inputs of a plurality of keys and discriminating a target key from other keys. The method also includes extracting keys around the target key and registering the keys around the target keys as neighbor keys. The method further includes processing the input of the target key while blocking the inputs of the neighbor keys. The method further includes releasing, when the target key is released, the blocking of the inputs of the neighbor keys.

摘要： An effective structure of a pixel cache for use in a three-dimensional (3D) graphics accelerator is provided. The pixel cache includes a z-data storage unit that reads z-data from a frame memory and provides the read z-data to a pixel rasterization pipeline; and a color data storage unit that in advance reads and stores color data from the frame memory at the same time when the z-data storage unit reads the z-data from the frame memory, and provides the color data to the pixel rasterization pipeline only when the result of predetermined z-test is determined to be a success in the pixel rasterization pipeline. Accordingly, the pixel cache structure enables only color data required to be read and stored in advance before processing of the color data, thereby preventing access latency, increasing the efficiency of a color cache, and reducing power consumption.

摘要： A floating-point ALU that performs an IEEE rounding and an addition in parallel in a simultaneous rounding method (SRM) type floating-point adder. The floating-point ALU includes an alignment/normalization section for bypassing or inverting a first fraction part and a second fraction part, performing an alignment by performing a right shift as much as a value obtained from an exponent part or performing a normalization through a left shift by calculating a leading zero with respect to the first fraction part, and obtaining a guard bit (G), round bit (R), and sticky bit (Sy); and an addition and rounding operation section for performing a addition and rounding with respect to the first fraction part and second fraction part outputted through the alignment/normalization section. According to the floating-point ALU, the processing time and the hardware size can be reduced, and the hardware of the SRM can be used as it is.

摘要： A 3D graphic accelerator and a method for processing a graphic acceleration using the same is provided in which the inputted primitives are geometrically processed, and existence of any transparent primitives or dominance/rarity of opaque primitives is determined among the geometrically processed primitives. The primitives are rendered in an object-order style and an image-order style in accordance with the determination. The information on the rendered primitives is stored in a corresponding frame buffer and a bucket, and the rendered primitives are display-refreshed. Thus, the 3D graphic accelerator with order- independent transparency and high performance is obtained.
