RECONFIGURING EVOLVED CIRCUITS USING CONTROLLER: A REAL TIME APPROACH

Abstract

FPGA is a device that contains a matrix of reconfigurable gate arrays that can implement different complex functions and also vary structurally. In this study, a novel method of reconfigurable circuit switching action is done with the help of a controller. BPSK Modulation application is chosen to demonstrate the reconfigurable action. When an event occurs the context/core switching is done at both input and output and also preserving the structural and functional relationship. The reconfiguration ability of FPGA with an embedded core performing the switching in real time is the focus of this study. A controller running on Linux platform is used along with the FPGA core. In this study, we propose a real time approach for reconfiguring evolved circuits using controller. It has an adaptive hardware that can continuously change in response to the input data and there by perform reconfiguration. Here the reconfiguration process is achieved by using a real time controller which gives a command to the FPGA core (ALTERA (Cypress processor)) for reconfiguration.
