Abstract: A reconfigurable VLSI architecture for 2D space-filtering operations was proposed, which is capable of supporting different window operations of infrared auto target recognition (ATR) applications, offering the possibility of addressing different image processing applications from the SoC perspective.Compared with other available architectural solutions, the proposed architecture gains better processing rate.The proposed architecture was fabricated with SIMC 0.18μm CMOS technology, and the maximum clock frequency, power consumption, and area are 135Mhz, 52mW, 128.2K Gates, respectively.The peak processing performance of the architecture achieves 6.6GOPs.
