Abstract

This paper describes the implementation of an iris recognition algorithm based on hardware-software co-design. The system architecture consists of a general-purpose 32- bit microprocessor and several slave coprocessors that accelerate the most intensive calculations. The whole iris recognition algorithm has been implemented on a low-cost Spartan 3 FPGA, achieving significant reduction in execution time when compared to a conventional software-based application. Experimental results show that with a clock speed of 40 MHz, an IrisCode is obtained in less than 523 ms from an image of 640x480 pixels, which is just 20% of the total time needed by a software solution running on the same microprocessor embedded in the architecture.
