how to implement a bilinear interpolation algorithm

hi,my friends:

        today ,i encounter a dificult problem that puzzle me so much.i design a graphics accelorator based on XILINX FPGA, in the raster stage,i will shade the triangle primitive with colors,in which supply the color information corresponding with the triangle's vertex information,i choose the Gourand shading algorithm with some consideration which utilize many Divider on implementaton,in the gourand shading altorithm ,it is bilinear interpolation that require many Divider.

       it is my plesure that any body will give me some suggestions about implementing this algorithm(gourand shading or bilinear interpolation) or my project. thanks.
