Abstract :
An image recognition processor, utilizing a phase only correlation (POC) algorithm is proposed. The arithmetic logical unit (ALU) in this processor can be re-configured dynamically. By arranging the POC algorithm to a form suitable for reconfigurable computing, the proposed processor can perform 2D 512×512 pixel image recognition within 105.2 ms and using 310.9 mW of power. This power consumption is 11.3 times lower than that of a previously reported work with same execution time.
