Abstract:
The Sobel square root algorithm Sa2bc-g2fe2a2Hg-c2-desquared, with 8-bit input data from a 3x3 window and 6-bit output is performed on a single VLSI chip, using a square table only 128x13 and a square root table only 1027 or 1032x6 in ROM. The random logic including adders and clock circuits are also on the same chip with the ROM tables. Author
