Systolic arrays for matrix multiplications

Development a New Technique Based on Least Square Method to Synthesize the Pattern of Equally Space Linear Arrays

Using the sampled data of a desired pattern is a common technique in pattern synthesizing of array factor (AF) of antenna arrays. Based on the obtained data matrix, Least Square Method (LSM) is used to calculate the exciting coefficient of array elements. The most important parameter, which involves the accuracy and complexity of calculation, is the sampling rate of the desired pattern. Classic...

A Review on VHDL Implementation for Adaptive Finite Impulse Response filter and its novel applications using Systolic Architecture

The evolution of computer and Internet has brought demand for powerful and high speed data processing. In such complex environment, the conventional methods of performing matrix multiplications are not suitable to obtain the perfect solution. To handle above addressed issue, parallel computing is proposed as a solution to the contradiction. The DLMS adaptive algorithm minimizes approximately th...

Error Detection in Arrays via Dependency Graphs y

This paper describes a methodology based on dependency graphs for doing concurrent run-time error detection in systolic arrays and wavefront processors. It combines the projection method of deriving systolic arrays from dependency graphs with the idea of input-triggered testing. We call the method ITRED, for Input-driven Time-Redundancy Error Detection. Tests are triggered by inserting special ...

Computation of Trigonometric Functions by the Systolic Implementation of the CORDIC Algorithm

Trigonometric functions are among the most useful functions in the digital signal processing applications. The design introduced in this paper computes the trigonometric functions by means of the systolic arrays. The method for computing these functions for an arbitrary angle, , is the CORDIC algorithm. A simple standard cell is used for the systolic array. Due to the fixed inputs, in some...
