Abstract: Systems and methods may provide a graphics processor that may identify operating conditions under which certain floating point instructions may utilize power to fewer hardware resources compared to when the instructions are executing under other operating conditions. The operating conditions may be determined by examining operands used in a given instruction, including the relative magnitudes of the operands and whether the operands may be taken as equal to certain defined values. The floating point instructions may include instructions for an addition operation, a multiplication operation, a compare operation, and/or a fused multiply-add operation.

Abstract: A processing apparatus is described. The apparatus includes a graphics processing unit (GPU), including a register file having a plurality of channels to store data and an execution unit to examine data at each of the plurality of channels, read a data value from a first of the plurality of channels upon a determination that each of the plurality of channels has the same data and execute a single input multi data (SIMD) instruction based on the data value.

Abstract: An apparatus and method are described for a high throughput rasterizer. For example, one embodiment of an apparatus comprises: block selection logic to select a plurality of pixel blocks associated with edges of a primitive, the plurality of pixel blocks selected based on the pixel blocks having samples which are both inside and outside of the primitive; and edge determination logic to analyze samples of the plurality of pixel blocks selected by the block selection logic and responsively generate data identifying each edge of the primitive; and final mask determination logic to combine the data identifying each edge and generate a final mask representing the primitive.
