PURPOSE: To provide the fractal coding circuit which is provided with a chaos characteristic and is suitable to handle digital data and has the circuit constitution simplified in a neural network. CONSTITUTION: This fractal coding circuit realizes the iterative function method using the affine reduction transformation by a cyclic circuit model of the neural network, and random numbers pi are calculated from an output (xk,yk) by a control part 13 of an operation processing part, and functions Wi corresponding to random numbers pi in the block size of picture element blocks are specified from the ROM table in a ROM 12 and are used to output (ei+1,pi+1) and (fi+1,pi+1) to the next circuit. |
