The coarse-grained reconfigurable image stream processor (CRISP) architecture is introduced for the image processing demands of high-definition (HD) cameras and camcorders. With several architectural concepts of the reconfigurable architecture, the CRISP architecture is proposed to meet the performance and flexibility requirements of the HD cameras. A multi-frame processing system with CRISP is implemented to achieve the real-time HD video recording and 11M-pixel image processing capability. Compared with the performance of the high-dynamic-range image fusion algorithm implemented with a general-purpose processor, 106 times speed-up is achieved by the proposed processor with high image quality of 42.5dB in PSNR.
