Pipelined adder graph solutions of the benchmark convolution matrices. (a) Gaussian 3 × 3 (B _c  = 8 bits; B _x  = 8, 10, 12 bits). (b) Gaussian 5 × 5 (B _c  = 12 bits; B _x  = 8, 10, 12 bits). (c) Laplacian 3 × 3 (B _c  = 8 bits; B _x  = 8, 10, 12 bits). (d) Unsharp 3 × 3 (B _c  = 8 bits; B _x  = 8, 10, 12 bits). (e) Unsharp 3 × 3 (B _c  = 12 bits; B _x  = 8, 10, 12 bits). (f) Lowpass 5 × 5 (B _c  = 8 bits; B _x  = 8, 10, 12 bits). (g) Lowpass 9 × 9 (B _c  = 10 bits; B _x  = 8, 10, 12 bits). (h) Lowpass 15 × 15 (B _c  = 12 bits; B _x  = 8, 10, 12 bits). (i) Highpass 5 × 5 (B _c  = 8 bits; B _x  = 8, 10, 12 bits). (j) Highpass 9 × 9 (B _c  = 10 bits; B _x  = 8, 10, 12 bits). (k) Highpass 15 × 15 (B _c  = 12 bits; B _x  = 8, 10, 12 bits).
