Abstract

PURPOSE:To filter a large amount of data at a high speed by arranging the same simple cells in two dimensions, and performing input/output operation and arithmetic processing operation simultaneously in parallel. CONSTITUTION:Only a picture element A1 is inputted and fetched in a cell 29. While the next picture element A2 is fetched in the cell 29, the sum of both picture elements A1 and A2 is generated in a cell 33. A picture element B1, on the other hand, is inputted to a cell 30. Then, the sum of A1, A2 and A3 is generated in a cell 37 and sent to a cell 41. Other cells are the same. Then, P1=A1+A2 +A3 is inputted and fetched in the cell 41. A cell 45 inputs P1 from the cell 41 and Q1=B1+B2+B3 from a data bus respectively, so the sum P1+Q1 is generated. A cell 48 inputs the sum P1+Q1 from left and above and R1=C1+C2+C3 from the data bus respectively, so the sum P1+Q1+R1 is calculated to obtain the total sum of 3X3 areas adjacent to an area 24.
