Design and Implementation of GDI Based Pipeline Architecture for NCO Using LUT
Keywords:Numerically Controlled Oscillator (NCO), Coherent control, Phase Separation, Look Up Table (LUT), Gate Diffusion Input (GDI)
Technical and economic problems are connected with the capacity extension of the grid to remote areas. Basically, Numerically Controlled Oscillator (NCO) is widely used in the applications of digital signal processing. In this paper, the design and implementation of GDI based pipeline architecture for NCO using LUT is done. In this phase separation will separates the phase difference signal based on the input signal and the oscillated signal. NCO generates a frequency- and phase tunable output signal with a precision fixed-frequency clock. 32 bit counter will compares the current count to the value stored in the compare register. Coherent control will control the carrier synchronizer by employing data from 32 bit counter. Index compute will save the obtained data after controlling.
