Wireless fingerprint collection device based on digital signal processor (DSP) and field programmable gata array (FPGA)

Abstract

The invention provides a wireless fingerprint collection device based on a digital signal processor (DSP) and a field programmable gata array (FPGA), which is respectively connected with the FPGA, a FLASH, a synchronous dynamic random access memory (SDRAM), a display module, a button module and a wireless transmission module which are all connected with the DSP. A VFDA02 fingerprint identification module is connected with the FPGA. The wireless fingerprint collection device uses a wireless network to transmit collection data, overcomes the problem that an attendance machine adopting a wiring mode to transmit the collection data is difficult in wiring in places with bad terrain environment and the like, and can achieve the fact that a plurality of fingerprint collection ports are communicated with a personal computer (PC) through wireless transmission, and the problem of insufficient ports is free of consideration.

Description

technical field [0001] The invention relates to the field of electronic technology, and provides a wireless fingerprint collection device based on DSP and FPGA. Background technique [0002] An important part of enterprise and business management is its personnel attendance system. Its quality directly affects the unit's economic and social benefits, as well as employees' salaries and many other aspects. Therefore, effective and scientific management of the attendance of employees in the unit has become an important issue faced by each unit. [0003] With the birth of the fingerprint attendance system, an advanced computer attendance management system, although the problem of unit examination has been solved, the traditional embedded automatic fingerprint identification system mostly uses a single-chip DSP or MIPS processor to complete the algorithm. Due to the DSP or MIPS processing The fingerprint reader can only be executed according to the sequence of the program, and c...

[0003] With the birth of the fingerprint attendance system, an advanced computer attendance management system, although the problem of unit examination has been solved, the traditional embedded automatic fingerprint identification system mostly uses a single-chip DSP or MIPS processor to complete the algorithm. Due to the DSP or MIPS processing The fingerprint reader can only be executed according to the sequence of the program, and can only be matched with the fingerprints in the entire library one by one during the fingerprint matching process, so the matching time of this type of system is quite long when dealing with a large fingerprint library
