P-CORDIC: A Precomputation Based Rotation CORDIC Algorithm
This paper presents a CORDIC (coordinate rotation digital computer) algorithm and architecture for the rotation mode in which the directions of all micro-rotations are precomputed while maintaining a constant scale factor. Thus, an examination of the sign of the angle after each iteration is no longer required. The algorithm is capable to perform the CORDIC computation for an operand word-lengt...
متن کاملThe CORDIC Householder algorithm
A novel n-dimensional (n-D) CORDIC algorithm. for Euclidean and pseudo-ELclidian rotations,% proposed. The new algorithm is closely related to Householder transformations. It is shown to converge faster than CORDIC algorithms developed earlier for n = 3 and 4. Processor architectures for the algorithm are presented. The area and time performance of n-D CORDIC processors are evaluated. For a com...
متن کاملA CORDIC Algorithm with Improved Rotation Strategy for Embedded Applications
Coordinate rotation digital computer (CORDIC) is an iterative algorithm to calculate various complex mathematical functions such as trigonometric, hyperbolic, logarithmic functions and so on. The iterative procedure of the conventional CORDIC algorithm is inefficient due to its rotation strategy. This research presents a resourceful rotation strategy to reduce the unnecessary iteration times. T...
متن کاملModified Vector Rotational CORDIC (MVR-CORDIC) Algorithm and Architecture
The CORDIC algorithm is a well-known iterative method for the computation of vector rotation. However, the major disadvantage is its relatively slow computational speed. For applications that require forward rotation (or vector rotation) only, we propose a new scheme, the modified vector rotational CORDIC (MVR-CORDIC) algorithm, to improve the speed performance of CORDIC algorithm. The basic id...
متن کاملFpga Implementation of Dswg Using Cordic Algorithm
The Coordinate Rotational Digital Computer (CORDIC) algorithm is another classic approach for sine wave generation. This trigonometric iteration based approach relies on vector rotations for performing successive mapping between polar and rectangular co-ordinates (and vice versa)
