In this paper, a hardware architecture of phase calculator for 3D image processing is proposed. The designed phase calculator, which adopts a pipelined architecture to improve throughput, performs arctangent operation using vectoring mode of CORDIC algorithm. Fixed- point MATLAB modeling and simulations are carried out to determine the optimized bit-widths and number of iteration. Phase calculator designed in Verilog HDL is verified by emulating the restoration of virtual 3D data using MATLAB/Simulink and FPGA-in-the-loop verification.
