/*
Excerpt from inner loop of bilinear interpolation filter operating on image component stored in an array pointed to by
r12. The width of the image is stored in r11 while the resulting filtered image is pointed to by r10. The coefficients of
the filter: A, B, C, D are already set before this code is executed. COEFF0_0 = A, COEFF0_1 = B, COEFF0_2 = 0,
COEFF1_0 = C, COEFF1_1 = D, COEFF1_2 = 0, COEFF2_0 = 0, COEFF2_1 = 0, COEFF2_2 = 0, OFFSET0 = 0.5
(For rounding the result), OFFSET1 = 0, OFFSET2 = 0.
The Input Selection Mode is set to Horizontal Filter Mode while the Output Insertion Mode is set to Planar Insertion
Mode.
The input image pointer might be unaligned, hence the use of ld.w instead of picold.w, while the output image pointer
is word aligned.
Four output pixels are computed in this example which show an example of a bilinear interpolation filter found in
the Motion Compensation used in the H.264 Video Standard.
