SIMD processor is different from general purpose processor, which is widely used in digital and video image processing. Data buffer system and aligning network are critical parts in SIMD processor. Since digital image convolution is the most important technology of image processing. After analyzed the image convolution algorithm, the architecture of image convolution coprocessor is presented. The architecture consists of interface unit, control unit, data buffer system,aligning circuit and processing units, etc. which absolutely aims at solution of hardware acceleration while'video image processing. Finally, the performance is analyzed in detail.
