Abstract
This paper proposes implementation of an Echo State Network (ESN) to Field
Programmable Gate Array (FPGA). The proposed method is able to reduce hardware
resources by using fixed-point operation, quantization of weights, which
includes accumulate operations and efficient dataflow modules. The performance
of the designed circuit is verified via experiments including prediction
of sine and cosine waves. Experimental result shows that the proposed circuit
supports to 200 MHz of operation frequency and facilitates faster computing
of the ESN algorithm compared with a central processing unit.
