This article proposes a new way to generate a sine and cosine waves based FPGA. These signals can be used to generate a PWM signals that can be used in SDR and DSP. It can be used in control system like control DC and AC motors. The problem is how can generate a sine and cosine waves that are composed of the positive and negative part. Any hardware accepts the values 0, 1 and can't accept the negative values, we used the mode two's components of numbers to represent the positive and negative samples and converted these results to decimal numbers, and we shifted a one half wave 8 bit to obtain the wave without distortion. We used MATLAB to generate the data of sine and cosine wave. We saved the data in ROM memory using VHDL language and we applied the results onto board spartan-3A FPGA.
