Description

We proposed a design methodology to implement case data directly onto FPGA chips. Case data(Pattern data)are converted into truth tables, and the tables are evolved to match unknown pattern data by using genetic algorithm. The evolved truth tables are simply implemented onto FPGA chips. By using the current high density FPGA chips, specialized pattern recognition chips for individual practical tasks can be repidly developed at user-sites. We applied this methodology to develop an English pronunciation reasoning chip. The chip was designed with 139K gates and its prototype showed a reasoning speed of 500 ns/phoneme and a reasoning accuracy rate of 71.5%.
