  • CAPE - VLSI Implementation of a Systolic Processor Array: Architecture, Design and Testing 

    Hemkumar, Nariankadu D.; Kota, Kishore; Cavallaro, Joseph R. (1991-06-20)
    The SVD is an important matrix decomposition in many real-time signal processing, image processing and robotics applications. Special-purpose processor arrays can achieve significant speed-up over conventioinal architectures ...
  • Efficient Complex Matrix Transformations with CORDIC 

    Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1993-06-20)
    Transformations of real and arbitrary 2 x 2 matrices are employed in parallel algorithms based on Jacobi-like precedures for matrix factorizations like the eigenvalue and the singular value decompositions. Cast in the ...
  • Jacobi-like Matrix Factorizations with CORDIC-based Inexact Diagonalizations 

    Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1994-06-20)
    We propose a CORDIC-based Jacobi-like method for parallel computation of the eigenvalues of Hermitian (and real symmetric) matrices and the SVD of real matrices using inexact diagonalizations. It is predicted on the fact ...
  • Redundant and Online CORDIC for Unitary Transformations 

    Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1994-08-20)
    Two-sided unitary transformations of arbitrary 2 x 2 matrices are needed in parallel algorithms based on Jacobi-like methods for eigenvalue and singulare value decompositions of complex matrices. This paper presents a ...
  • Simulation of Systolic Arrays On The Connection Machine 

    Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1993-09-20)
    The use of a programming model which extends naturally from the underlying hardware, greatly eases the design and implementation of simulators, especially for those systems that resemble the hardware in the paradigm of ...

  • A Systolic VLSI Architecture for Complex SVD 

    Hemkumar, Nariankadu D.; Cavallaro, Joseph R. (1992-05-20)
    A systolic algorithm for the SVD of arbitrary complex matrices, based on the cyclic Jacobi method with "parallel ordering" is presented. A novel two-step, two-sided unitary transformation scheme, tailored to the use of ...
