- 論文の詳細を見る
A circuit that carries out an Hadamard transform of an input image using the pulse width modulation technique is proposed. The proposed circuit architecture realizes the function of an Hadamard transform with a full-size pixel image. A test chip that we designed and fabricated integrates 64 × 64 pixels in a 4.9mm × 4.9mm area, with 0.35 μm CMOS technology. The functional operation and linearity of this chip are measured. An image processing application utilizing this chip is demonstrated.
