In this paper, a practical and cost-efficient fingerprint recognition system model is proposed. It completes the functions
of capturing fingerprint image, data transmission and fingerprint recognition. This system consists of six modules:
Management Module (including TMS320VC5502 DSP and memories), Fingerprint Sensor Module (used to collect
fingerprint image), Output Module (the interface to control electronic lock), Human-Machine Communication Module
(seven-segment LED and keyboard), Debugger Interface Module (JTAG), Power Manager and Power Switchover
Module. Unlike other fingerprint recognition systems, this system takes TI C5502 as core processor. It is a high-performance,
low-power and fixed-point DSP and the whole system power can be supplied by batteries. The whole
system can work more than 10000 times with batteries. In addition, a Power Switch Module, which can automatic switch
the ways of power supply between wall adapter and batteries, is proposed in this paper. Furthermore, some software
optimization makes this system practical. The design not only simplifies system's structure and reduces the cost of
hardware, but also decreases the consumption of system power and resources. So, this hardware system can be used in
practical applications, such as portable identification device, fingerprint lock etc. This system is mainly designed for
fingerprint lock in this paper.
