摘要： Briefly, in accordance with one or more embodiments, a processor receives an incoming data stream that includes alpha channel data, and a memory stores an application programming interface (API). The API is to route the alpha channel data to a fixed point blending unit to perform one or more blending operations using fixed point representation of the alpha channel data. The API is further to route the incoming data stream to a floating point blending unit to perform operations involving floating point representation of the incoming data.

摘要： Briefly, in accordance with one or more embodiments, a processor receives an incoming data stream that includes alpha channel data, and a memory stores an application programming interface (API), wherein the alpha channel data is to be routed to a fixed point blending unit to perform one or more blending operations using fixed point representation of the alpha channel data. A first Finite Impulse Response (FIR) filter is coupled to the fixed point blending unit and operates at a lower precision. A second FIR filter is coupled to the fixed point blending unit and operates at a second precision that corresponds to a difference between a higher precision and the lower precision.
