摘要： Provided is a method and apparatus of selecting a preemption technique for a computation unit included in a processor to execute a second task before the at least one computation unit finishes executing a first task. The method includes receiving a preemption request, predicting a cost of preemption techniques based on a progress of the first task until receipt of the preemption request, and selecting one of the preemption techniques based on the predicted cost.

摘要： Provided are apparatuses and methods for rendering. The methods analyze draw commands and graphics states, generate hierarchical graphics states from the graphics states based on a graphics state common to the draw commands, and perform rendering of an image frame based on the hierarchical graphics states. The apparatuses use a hierarchical state generator and a graphics processing unit (GPU) to perform the rendering method.

摘要： A curve rendering method includes calculating a step size based on a length of a straight line connecting a start point and an end point among control points of a curve to be rendered, and calculating initial values of a forward differencing algorithm (FDA) based on the calculated step size and coefficient values of an equation of the curve that is determined based on the control points. The method further includes generating an FDA table based on the initial values, and calculating a coordinate value of a pixel based on the FDA table.

摘要： A method and apparatus for optimizing a configuration memory of a reconfigurable processor is provided. The method of optimizing the configuration memory of the reconfigurable processor includes analyzing parallelism of a loop of a program code based on an architecture of the reconfigurable processor and information regarding the configuration memory, scheduling groups of function units (FUs) to be activated in each cycle of the loop based on the analyzed parallelism, generating configuration data of each cycle, and determining a memory mapping to store the generated configuration data in the configuration memory.

摘要： Multiple-thread processing apparatuses and methods are provided. The multiple-thread processing method may include searching for loops in a plurality of threads, calculating a number of repetitions of each of found loops in respective threads among the plurality of threads, determining one or more threads based on the calculated number of repetitions of each of the found loops, dividing at least one of the one or more determined threads into child threads, and processing the child threads separately from one another in the plurality of threads.

摘要： Methods and apparatuses for determining a work-group size are provided. The method of determining a work-group size includes calculating a first value denoting spatial locality of a memory that is shared by one or more work items included in a work-group, calculating a second value denoting footprints of the one or more work items included in the work-group based on the first value, and determining the work-group size based on the first and second values.
