Selective Rasterization

A graphics processing unit comprising:

• first circuitry to:
• organize pixels, generated in response to execution in a draw call, into tiles;
• determine whether a first tile processed after a second tile matches a characteristic of the second tile;
• set a bit to indicate if characteristics of the first and second tiles match;
• if the first tile matches the second tile based on the bit, forego rendering for the first tile;
• if the first tile does not match the prior second tile, based on the bit, render the first tile;
• and
• second circuitry to determine a hash for a third tile and a fourth tile, and if said hashes match, reduce processing of one of said third and fourth tiles.

A system comprising:

• a graphics processing unit to:
• organize pixels, generated in response to execution in a draw call into tiles;
• determine whether a first tile processed after a second tile matches a characteristic of the second tile;
• set a bit to indicate if characteristics of the first and second tiles match;
• if the first tile matches the second tile based on the bit, forego rendering for the first tile;
• if the first tile does not match the prior second tile, based on the bit, render the first tile;
• determine a hash for a third tile and a fourth tile, and if said hashes match, reduce processing of one of said third and fourth tiles;
• and
• a storage coupled to said graphics processing unit.

A method comprising:

• organizing pixels, generated in response to execution in a draw call, into tiles;
• determining whether a first tile processed after a second tile matches a characteristic of the second tile;
• setting a bit to indicate if characteristics of the first and second tiles match;
• if the first tile matches the second tile based on the bit, foregoing rendering for the first tile;
• if the first tile does not match the prior second tile, based on the bit, rendering the first tile;
• and
• determining a hash for a third tile and a fourth tile, and if said hashes match, reduce processing of one of said third and fourth tiles.

One or more non-transitory computer readable media storing instructions to perform a sequence comprising:

• organizing pixels, generated in response to execution in a draw call, into tiles;
• determining whether a first tile processed after a second tile matches a characteristic of the second tile;
• setting a bit to indicate if characteristics of the first and second tiles match;
• if the first tile matches the second tile based on the bit, foregoing rendering for the first tile;
• if the first tile does not match the prior second tile, based on the bit, rendering the first tile;
• and
• determining a hash for a third tile and a fourth tile, and if said hashes match, reduce processing of one of said third and fourth tiles.
