The high resolution direction of arrival (DOA) estimation has been an important area of research for a number of years. Many researchers have developed a variety of algorithms to estimate the direction of arrival. Another important aspect of the DOA estimation area is the development of high speed hardware capable of computing the DOA in real time. In this research the authors have first focussed on the development of parallel architecture for multiple signal classification (MUSIC) and estimation of signal parameters by rotational invariance technique (ESPRIT) algorithms for the narrow band sources. These algorithms are substituted with computationally efficient modules and converted to pipelined and parallel algorithms. For example one important computation of eigendecomposition of the covariance matrix has been performed using Householders transformations and QR method.
