In this paper, a main perspective of developing and implementing fingerprint extraction and matching algorithms as a part of fingerprint recognition system is focused. First, developing a simple algorithm to extract fingerprint features and test this algorithm on PC. The second thing is implementing this algorithm into FPGA devices. The major research topics on which the proposed approach is developing and modifying fingerprint extraction feature algorithm. This development and modification are using crossing number method on pixel representation value '0'. In this new proposed algorithm, it is no need a process concerning ROI segmentation and no trigonometry calculation.
