Dedicated fixed point blending for energy efficiency

A method comprising:

• receiving an incoming data stream that includes alpha channel data;
• and
• routing 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,
• wherein a first Finite Impulse Response (FIR) filter, coupled to the fixed point blending unit, operates at a lower precision and a second FIR filter, coupled to the fixed point blending unit, operates at a second precision that corresponds to a difference between a higher precision and the lower precision.

One or more non-transitory computer-readable media comprising one or more instructions that, if executed on at least one processor, configure the at least one processor to perform one or more operations to:

• receive an incoming data stream that includes alpha channel data;
• and
• 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,
• wherein a first Finite Impulse Response (FIR) filter, coupled to the fixed point blending unit, is to operate at a lower precision and a second FIR filter, coupled to the fixed point blending unit, is to operate at a second precision that corresponds to a difference between a higher precision and the lower precision.
