Selecting a Target System

Selecting a target system for your real-time application consists of three major

steps: selecting the form factor, selecting the I/O boards, and selecting the

CPU. You should, if possible, follow these steps in order.

This section includes the following topics:

• Selecting the Form Factor

• Selecting I/O Boards

• Suggested Method for Selecting I/O Boards

• Useful Tips for Selecting I/O Boards

• Selecting the CPU

Selecting the Form Factor

The key to determining the best form factor for your application is

understanding the environment in which the target hardware is placed.

Typical environmental constraints include:

• Lack of space for the target system

• Wide temperature range

• Mechanical vibration and shock

• Water and dust

• Electromagnetic interference (EMI)

The range of environmental conditions your hardware must endure can be very

broad. At one end of the spectrum is a clean environment. For example, a clean

environment could be an office that is climate controlled and has no mechanical

or electrical interference. At the other end of the spectrum is a harsh, cramped

environment with vibration, water, dust, EMI, and extreme temperatures. For

example, a harsh environment would be on-board a heavy equipment vehicle

operating in the field.
