An image processing method includes: determining whether a draw command that is identical to a previous draw command is input; obtaining information about a transparency of a previous frame that is performed with the previous draw command; and performing image processing on a current frame based on the information about the transparency.

Apparatus, method and non-transitory computer-readable medium for image processing based on transparency information of a previous frame

A cache memory system includes a cache memory, which stores cache data corresponding to portions of main data stored in a main memory and priority data respectively corresponding to the cache data; a table storage unit, which stores a priority table including information regarding access frequencies with respect to the main data; and a controller, which, when at least one from among the main data is requested, determines whether cache data corresponding to the request is stored in the cache memory, deletes one from among the cache data based on the priority data, and updates the cache data set with new data, wherein the priority data is determined based on the information regarding access frequencies.

Cache memory system and operating method for the same

A rendering method includes determining, at a geometry processor, if a previous draw command from among previous draw commands is identical to a current draw command; in response to the previous draw command being identical to the current draw command, selecting a primitive list indicating a result of geometry processing performed on the previous draw command; and performing pixel processing using the primitive list.

Rendering method and apparatus

A method and apparatus for rendering graphics data are provided. The graphics data rendering method includes calculating a number of overlapping objects by tile in a first frame. The graphics data rendering method determines a tile size of a second frame based on the calculated number of the overlapping objects, divides the second frame based on the determined tile size, and renders the second frame by divided tile.

Apparatus and method for tile-based graphic data rendering

Image processing apparatus and method for processing transparency information of drawing commands

Provided is a rendering method and apparatuses for rendering image data. The rendering method includes generating a primitive list by performing geometry processing on a current tile to be rendered; determining whether the current tile is identical to a previous tile from among tiles included in a previously rendered frame; and in response to the previous tile being identical to the current tile, generating an image of the current tile by re-using an image of the previous tile.

Method and apparatus for rendering image data

A rendering apparatus and method are provided. The rendering method includes: reading a block, corresponding to a fragment, from among compressed blocks stored in a depth buffer, by considering frequency information corresponding to the fragment and prepared in advance; and performing a depth test for the fragment by considering the restored block.

Method and apparatus for rendering

Provided are a method and apparatus for avoiding bank conflict. A first instruction that is one of access instructions that are predicted to cause the bank conflict is replaced with a second instruction by changing an execute timing of the first instruction to a timing prior to the execute timing of the first instruction so as for the access instructions not to cause the bank conflict. Next, a load/store unit that is scheduled to access the bank according to the first instruction accesses the bank and reads out a data from the bank at an execute timing of the second instruction, and after that, the load/store unit is allowed to be inputted the read data at the execute timing of the first instruction. Accordingly, although the access instructions that are predicted to cause the bank conflict are allocated to the load/store units, the bank conflict can be prevented, so that it is possible to avoid deterioration in performance due the occurrence of the bank conflict.

Apparatus and method of avoiding bank conflict in single-port multi-bank memory system

Provided is a method and apparatus for rendering 3D graphics data. By calculating the size of a primitive, which is a basic constituent unit of objects indicated by the graphics data, on a screen, selecting one of a plurality of resolutions supported by a video stream according to the calculated size, generating a video frame image having the selected resolution from the video stream, and rendering the graphics data using the generated video frame image, the amount of memory space used and power consumed are reduced. In addition, since when rendering is performed using a video frame image decoded at a low resolution, a processing speed increases, and since rendering can be performed using video frame images decoded at various resolutions, image quality increases.
