Abstract: This paper presents a new approach for designing a neural network based path planning algorithm in an Integrated Circuit by using the VHDL.The structure of the VHDL provides a convenient construct for the implementation of neural network into electronichardware.In addition,with VHDL analyzer and logic synthesissoftware,hardware prototypes can be implemented in FPGA.It is of wide use with its high stablization.

Key words: BP neural network；path planning, VHDL
