Abstract: Provided is a method of managing commands, which includes receiving a frame buffer object (FBO) change command, comparing an FBO designated by the FBO change command with a FBO currently processed by a graphics processing unit (GPU) to determine whether the two FBOs are the same as each other, and managing the FBO change command or a flush command based on a result of the comparison.

Abstract: Computing apparatus and methods are provided for performing a tile-based graphics pipeline. The graphics pipeline includes a binning pipeline configured to generate a tile list of objects indicating which tile vertices, primitives, or patches the objects belong to; and a rendering pipeline configured to render an object, per tile, based on the tile list generated in the binning pipeline. Each of the binning pipeline and the rendering pipeline is configured to implement a tessellation pipeline. The graphics pipeline may be configured to operate in an efficiency mode to defer or lower tessellation by performing tessellation in one of the binning and rendering pipelines or by setting a new lower tessellation factor.

Abstract: A cache memory apparatus includes a tag comparator configured to compare upper bits of each of pieces of tag data included in a set indicated by a set address that is received with upper bits of a tag address that is received, compare other bits of each of the pieces of the tag data with other bits of the tag address, and determine whether there is a cache hit or a cache miss based on results of the comparisons, and an update controller configured to, in response to the cache miss, determine, as an update candidate, a piece of cache data included in the set and corresponding to the pieces of the tag data, based on the result of the comparison of the upper bits of each of the pieces of the tag data and the upper bits of the tag address, and update the update candidate with new data.

Abstract: A texture processing method of processing a compressed texel block in which texels constituting a texture are compressed into a predetermined block unit includes obtaining, based on the compressed texel block, a representative value of texels constituting a texel block, a weight for each of the texels constituting the texel block, and an index of the representative value and the weight corresponding to each of the texels constituting the texel block; storing the representative value, the weight, and the index in a texture cache; reading the representative value and the weight from the texture cache according to an index corresponding to a requested texel; generating texels based on the read representative value and the read weight; and performing texture filtering using the generated texels.
