FPGA IMPLEMENTATION OF BIDIRECTIONAL ASSOCIATIVE MEMORY US I N G SI M U LTAN EO US P ERTU R BAT IO N

Recurrent neural networks have interesting properties and can handle dynamic information processing unlike the ordi- nary feedforward neural networks. Bidirectional associative mem- ory (BAM) is a typical recurrent network. Ordinarily, weights of the BAM are determined by the Hebb's learning. In this paper, a recursive learning scheme for BAM is proposed and its hardware implementation is described. The learning scheme is applicable to analogue BAM as well. A simulation result and details of the implementation are shown.
