| Abstract: | The general principle of the fingerprint identification is presented. The modular structures and functions of CPU S3C2440A and HB7121B are described in detail. The connections between CPU S3C2440A and fingerprint identifier HB7121B are given, thus the hardware design of the identifier is implemented. In addition, the embedded operating system Linux and the programming of application software are discussed, thus the software design is accomplished. In the design, the ARM9 technology has been involved in the area of fingerprint identifier. This will promote the application of ARM technology and development of fingerprint identification. |
