Abstract
Biometric systems, characterized by their high confidential
levels of security, are usually based on high-performance
microprocessors implemented on personal computers.
These advanced devices contain floating-point units able to
carry out millions of operations per second at frequencies in
the GHz range, being qualified to resolve the most complex
algorithms in just a few hundred of milliseconds. However,
their main drawback is the cost, and the necessary space
required to incorporate their external associated peripherals.
This disadvantage is especially significant in the low-cost
consumer market, where factors such as price and size
determine the viability of a product. The use of an FPGA is
a suited way to implement systems that require a high
computational capability at affordable prices. Besides, these
devices allow the design of complex digital systems with
outstanding performances in terms of execution times. This
paper presents the implementation of a SVM (Support
Vector Machines) speaker verification system on a low-cost
FPGA. Experimental results show as our system is able to
verify a person’s identity as fast as a high-performance
microprocessor based on a Pentium IV personal computer.
