PURPOSE:To perform the window operation of an optional size by connecting selectively each output of buffer modules connected in a pipeline form to each input of arithmetic modules connected in a pipeline form via a switch circuit. CONSTITUTION:The outputs of an input data terminal 2 and buffer modules 11, 12...1n-1 which are connected to the terminal 2 in a pipeline form are connected to a switch circuit 4. Then each switch output is connected selectively to (mXn) units of arithmetic modules 31, 32, 3...3mxn which are connected in a pipeline form. When (3X3) units of window arithmetic circuits are formed, the terminal 2 is connected to arithmetic modules 37, 38 and 39 respectively via the circuit 4. Then the output of the module 11 is connected to arithmetic modules 34, 35 and 36 via the circuit 4. Then the output of the module 12 is connected to arithmetic modules 31, 32 and 33 respectively via the circuit 4. |
