With the improvement of automation, complexity, accuracy and reliability of measurement and control system, people have higher and higher requirements on sensor performance. However, some shortcomings of the traditional sensor itself restrict this development, so people have introduced high-tech represented by microprocessor. To reduce the time taken to configure the sensor and the risks involved in this process, recently IEEE

Abstract: This paper improves the fingerprint processing algorithm on the basis of fingerprint automatic recognition technology, and gives the design scheme of a master-slave fingerprint automatic recognition system based on Motorola DSP56311 and MCS-51. Keywords: Automatic fingerprint recognition system; Signature code; MCS-51; Introduction to DSP56311 Biometric technology is developing rapidly
