Description

In our project we propose a pipeline hyperbolic CORDIC processor to implement a direct digital synthesizer (DDS).The DDS is also used to derive an efficient arbitrary waveform generator (AWG), where a pseudo-random number generator modulates the linear increments of phase to produce random phase-modulated waveform. It uses most-significant-1 bit detection technique used for micro-rotation sequence generation to reduce the number of iterations. By storing the sinh/cosh hyperbolic values at LUT in a ROM, we can extend the range of convergence to the entire coordinate space. The waveforms generated by the proposed AWG have large number of frequency components. In our existing system, improved the range of convergence of conventional CORDIC algorithm in hyperbolic trajectory by using additional iterations. It allows negative iteration indices as well. Though it increases the RoC of the hyperbolic CORDIC algorithm. It significantly adds to the latency of the processor. It uses three architectures,
