Two structures of the processors for the autoregressive analysis are considered. 
The first of them implements the Durbin algorithm using the rational fraction calculations. 
The second of them implements the adaptive lattice filter. 
The processors give the possibility of the signal analysis 
with the sampling frequency up to 300 MHz being configured in FPGA. 
The processors can be effectively used for adaptive filtering and 
pattern analysis in the ultrasonic installations, radars, software defined radio, etc.
