Abstract
A novel systolic array for the nonsquare-root LDLT method of Cholesky decomposition is presented. The systolic array is an alternative to th at proposed by Brent and Luk; displaying an improvement in efficiency and a lower hardware cost, arising from a reduction in the number of m ultipliers required. An application for the array is in real-time digi tal signal processing hardware such as the modified covariance spectra l estimator; which when used in conjunction with pulsed ultrasonic Dop pler blood flow detectors, offers potentially improved sensitivity in the detection of atherosclerotic disease.
