Design of Low Power COrdic based Robotic Processor to Improve the Performance of Armdroid Robot

Background: The advent of reconfigurable computers allows for a higher performance of dedicated hardware solutions that are competitive with a conventional software approach. A CoOrdinate Rotation DIgital Computer (CORDIC) circuit is used in the performance of smart robot applications. Objective: This paper examines the design and implementation of a CORDIC cell-based robotic processor with Pass Transistor Logic (PTL) for an application in an armdroid robot. The components of a COrdicbased Robotic Processor (CORP) are proposed, consisting of a tri-state buffer, flip-flop, demultiplexer, multivibrator and CORDIC cell with designed and generated layouts. Results: Proposed CORP design reduces power dissipation, improves speed and reduces delay to improve the performance of Armdroid robot. Conclusion: The BSIM4 is used to evaluate the performance of the CORP in anticipation of its use in the armdroid robot. The CORP output parameters are calculated from the robotic processor layout. From the simulated result analysis, the proposed CORP circuit performs better with respect to speed, power and propagation delay. This paper also presents the parametric analysis results, including measured power dissipation and leakage current through the load capacitance and supply voltages that gives better performance.
