Apparatus and method for performing tile-based rendering using prefetched graphics data

A method of performing tile-based rendering using prefetched graphics data in a graphics processing unit (GPU), the method comprising:

• performing binning on a current frame and obtaining a first binning bitstream of a first tile among a plurality of tiles of the current frame;
• determining whether the first tile and a second tile of a previous frame are similar to each other by using the first binning bitstream and a second binning bitstream of the second tile, wherein the second tile has a same tile ID as the first tile;
• prefetching second graphics data used to render the second tile by using the tile ID when it is determined that the first tile and the second tile are similar to each other;
• and
• rendering the current frame using the prefetched second graphics data.

A system on chip (SoC) comprising:

• a central processing unit (CPU) configured to execute an application by controlling an operation of the SoC;
• and
• a graphics processing unit (GPU) configured to perform tile-based rendering using prefetched graphics data,
• wherein the GPU comprises:
• a tiler configured to perform binning on a current frame and obtain a first binning bitstream of a first tile among a plurality of tiles of the current frame;
• a binning correlator configured to determine whether the first tile and a second tile of a previous frame are similar to each other by using the first binning bitstream and a second binning bitstream of the second tile, wherein the second tile has a same tile ID as the first tile;
• a prefetcher configured to prefetch second graphics data used to render the second tile by using the tile ID, when it is determined that the first tile and the second tile are similar to each other;
• and
• at least one processor configured to render the current frame by using the prefetched second graphics data.
