| 1. An apparatus to blend two images, the apparatus comprising:
a vector register file having a plurality of vector registers;
a vector processing unit coupled to the vector register file, the vector processing unit having a vector look up unit adapted
to look up a vector of data items simultaneously, wherein the vector processing unit is configured to load a vector of keys
into a vector register in the vector register file, convert the vector of keys into a first vector of blending factors for
a first image and a second vector of blending factors for a second image using a plurality of look up tables in the vector
look up unit, and
compute an image attribute for a blended image using the blending factors.
