Defining a Distributed System

System that uses two or more processors to solve an application

• Distributed systems can be physically located on a single board, box, or rack; or spatially distributed in separate devices or systems on a network

• Processors can be of mixed architectures including MPUs, DSPs, or FPGAs

MPU FPGA

Ad hoc networks Multi-processors in single box Heterogeneous processors on single board

Typical Distributed Application

• PCs, PACs, PLCs • Control

• Monitoring

• Motion

• Vision

• Communication • .NET

• OPC

• Database logging

Linux Operating System Background

• Operating system created under the model of free and open source software development and distribution

• First released in 1991 for x86 but has been ported to other computer hardware platforms including ARM

• Common OS for servers and big mainframes

• Linux is used in a wide breath of embedded systems including:

• Mobile phones (Android)

• Tablets

• Network routers

• Televisions

• Video game consoles

What makes our Linux flavor unique?

Pre-emption offered through RT scheduler to make Linux deterministic

Jitter is on the same order of magnitude as other RTOSs

S.E.A Structural Monitoring

“By leveraging the open Linux-based real-time operating system on a commercial off-the-shelf controller, we could port our existing Linux software components in a very short time. That saved

us at least four months of development time.”
