The image recognition processor we propose implements the phase-only correlation (POC) algorithm. Its arithmetic-logic unit (ALU) is dynamically reconfigurable to any necessary circuitry for POC by itself. 2-stage cached-memory architecture (CMA) is developed so that high-radix batch processing is possible. By transforming the original POC algorithm into the optimum form for the dynamically reconfigurable ALU and 2-stage CMA, the proposed processor executes two-dimensional 512×512 pixel image recognition within 105.2msec and 310.9mW at 80MHz in an area 3.7×3.7mm². Its power consumption is over 11.3 times lower than that of previously reported work.
