20130342528 | APPARATUS AND METHOD FOR TRAVERSING HIERARCHICAL ACCELERATION STRUCTURE - An apparatus and method for traversing a hierarchical acceleration structure may determine whether a current traversal node is a leaf node, may calculate a first distance from the current traversal node to a pop level and a second distance from a root node to the pop level when the current traversal node is the leaf node, and may determine a hierarchical traversal restarting position by comparing the first distance and the second distance. | 12-26-2013 |
20140019782 | APPARATUS AND METHOD FOR MANAGING POWER BASED ON DATA - Provided is an apparatus and method for managing power based on data. The apparatus may include a code segment searching unit configured to search for at least one code segment in which a power type is inserted, a block determining unit configured to determine at least one block based on the at least one found code segment, and a power mode control unit configured to control the at least one determined block to operate in a power mode corresponding to the power type. | 01-16-2014 |
20140032976 | APPARATUS AND METHOD FOR DETECTING ERROR - An apparatus and method for detecting an error occurring when an application program is executed in a computer environment is provided. The error detection apparatus may measure a deterministic progress index (DPI) and a program counter (PC) value when an instruction is executed, set, as a verification set, a DPI and a PC value measured when the instruction is executed without causing an error, set, as a measurement set, the DPI and the PC value measured when an instruction is executed, and detect a runtime error of the instruction by comparing the measurement set to the verification set. | 01-30-2014 |
