CORDIC arithmetic for an SVD processor

CORDIC Processor for Variable-Precision Interval Arithmetic

In this paper we present a specific CORDIC processor for variable-precision coordinates. This system allows us to specify the precision to perform the CORDIC operation, and control the accuracy of the result, in such a way that re-computation of inaccurate results can be carried out with higher precision. It permits a reliable and accurate evaluation of a wide range of elementary functions. The...

A complex arithmetic digital signal processor using CORDIC rotators

Architectural, Numerical and Implementation Issues in the VLSI Design of an Integrated CORDIC-SVD Processor

The Singular Value Decomposition (SVD) is an important matrix factorization with applications in signal processing, image processing and robotics. This thesis presents some of the issues involved in the design of an array of special-purpose processors connected in a mesh, for fast real time computation of the SVD. The systolic array implements the Jacobi method for the SVD. This involves plane ...

An Efficient Cordic Processor for Complex Digital Phase Locked Loop

Volume 2, Issue 2 March – April 2013 Page 306 Abstract—Now-a-days various Digital Signal Processing systems are implemented on a platform of programmable signal processors or on application specific VLSI chips. Coordinate Rotation Digital Computer (CORDIC) algorithm has turned out to be such kind of programmable signal processor. In recent times, it has been a widely researched topic in the fie...

CORDIC-Augmented Sandbridge Processor for Channel Equalization

In this paper we analyze an architectural extension for a Sandbridge processor which encompasses a CORDIC functional unit and the associated instructions. Specifically, the first instruction is CFG CORDIC that configure the CORDIC unit in one of the rotation and vectoring modes for circular, linear, and hyperbolic coordinate systems. The second instruction is RUN CORDIC that launches CORDIC ope...
