An Overview of Systolic Array Concepts and Applications for Linear Algebra and Signal Processing

Abstract

Modern communication, control, avionic, and radar systems require the use of computationally intensive algebraic operations for real-time high throughput filtering, estimation, tracking, direction-of-arrival, and localization purposes. In this overview paper, we first review some basic systolic array (SA) concept, then SA algorithms for digital filtering, recursive least-squares, QR decomposition, Kalman filtering, eigenvalue and singular value decompositions will be discussed.
