Objectives: To design a COordinate Rotation DIgital Computer (CORDIC) based electrical signal processing system for efficient and minimalist electrical power processing. Methods: This stage of assessment describes the design and performance of a true RMS (Root-Mean Square) voltage meter on Xilinx SPARTAN 3E 1600 FPGA. Findings: The effectiveness of the proposed designs is assessed through FPGA implementations and error simulations. Measurement results show that the model can reproduce behaviors similar to the original model traditional use of multipliers, but with less resource consumption (hardware and processing time). Novelty: The use of CORDIC to reduce the computational cost of the algorithm, and its implementation in an embedded system. Keywords: CORDIC, Embedded System, FPGA, Real-Time, True RMS
