Conventions

To help you effectively read this guide, we use some conventions. Conventions are the ways of consistently formatting the text and graphics.

This section includes the following topics:

• Terminology
• Typographical Conventions

Terminology

The following table lists some of the terms we use in the Real-Time Windows Target User's Guide.

Term	Definition
application	See real-time application.
build process	Process of generating C code from your Simulink model, compiling and inlining the generated code to create a real-time executable.
execution	Running the executable code on the target PC in real-time.
executable code	See real-time application.
external mode	Simulink mode that uses a Simulink block diagram as a graphical user interface to a real-time executable. This interface provides parameter downloading and signal uploading for display using Scope blocks.
kernel	Software component that handles system interrupts and regulates time interrupts when model code is stepped.
parameter tuning	Process of changing block parameters and downloading the new values to a real-time executable while it is running.
real-time application	Code ready to run in real-time with the kernel.
sample rate	Inverse of the sample time given as samples/second.
sample time	Length of time, in seconds, between each interrupt that the model is stepped.
self-targeting system	A system where both the development environment and real-time environment use the same processor.
signal logging	Acquire and save signal data created during a real-time execution.
signal tracing	Acquire and display of a sequence of bursts of signal data created during real-time execution. The burst length corresponds with the time axis at the Scope block.

Typographical Conventions

Typographical conventions are ways of formatting the text to indicate terms, objects, and dialog between the user and the computer. The following table lists the notational conventions used in the Real-Time Windows Target User's Guide.

Item	Convention to Use	Example
Keys	Boldface with an initial capital letter	Press Return.
MATLAB output and code	Monospace font	MATLAB displays the message   model rtwindemo loaded
Menu names, menu items, and command buttons	Boldface with an initial capital letter	From the File menu, click New. Click the Apply button.
New terms	Italics	A real-time application is created during the build process.
