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： 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.

Thus, the 3D graphic accelerator with order- independent transparency and high performance is obtained.

摘要： A pipelined divider with a small lookup table is disclosed. The pipelined divider can greatly reduce the size of a lookup table with a low cost to overcome the problems involved in the conventional pipelined divider requiring a large lookup table due to its iterative operation type. The pipelined divider has a delay time of 3 cycles in a single precision, and can reduce a chip size by about ⅓ in comparison to the existing pipelined divider.
