Summary:This paper compares software and FPGA-based hardware
implementations of two applications. The first application uses hidden
Markov models, and the second application is a fuzzy controller. Hidden
Markov modeling is used for temporal pattern recognition and speech
recognition in particular. Both applications are accelerated when
implemented in FPGA-based hardware, but this acceleration is obtained by
using different algorithms than those used in software implementations.
These different algorithms produce slightly different outputs; therefore
both solution quality and performance must be evaluated to compare
hardware and software implementations. The experience of designing these
applications has implications for hardware/software codesign tools and
for the migration of existing software applications to FPGA-based
hardware
