摘要
Abstract
A pipelined VLSI architecture for three-pass rotation algorithm was proposed, in which a buffer scheme was used. This architecture buffers the intermediate results in the dislocated order and stores the offsets in the horizontal direction separately. As a result, both the area of on-chip memory and the amount of pixels processed were reduced. The design was fabricated by SIMC （Semiconductor Manufacturing International Corporation） 0.18 μm CMOS （complementary metal oxide semiconductor） technology. Experimental results show that it only takes 3.81 ms at 100 MHz to rotate a 512 × 512 image by the angle 45°, which meets the real-time requirement for many application systems.关键词
