14. Glossary

ABI

Application Binary Interface

Architecture

Family or class of processor based around a common instruction set. RTEMS architectures follow the GCC architecture model as RTEMS needs an GCC architecture compiler for each support RTEMS architecture.

APA

Arbitrary Processor Affinity

API

Application Programming Interface

Binutils

GNU Binary Utilities such as the assembler as, linker ld and a range of other tools used in the development of software.

BSP

Board Support Package is a specific configuration RTEMS can be built for. An RTEMS install process installs specific library and headers files for a single BSP. A BSP optimises RTEMS to a specific target hardware.

Buildbot

A continuous inteagration build server.

C11

ISO/IEC 9899:2011

C++11

ISO/IEC 14882:2011

Crosscompiler

A compiler built to run on a Host that generate code for another architecture.

DLL

Dynamically Linker Library used on Windows.

EDF

Earliest Deadline First

EMB²

Embedded Multicore Building Blocks

FAT

File Allocation Table

Futex

Fast User-Space Locking

IMFS

In-Memory File System

JFFS2

Journalling Flash File System version 2

GCC

GNU Compiler Collection

GDB

GNU Debugger

GNU

GNU’s Not Unix

Host

The computer and operating system that hosts the RTEMS development tools such as the compiler, linker and debugger.

MinGW

Minimal GNU system for Windows that lets GCC built programs use the standard Windows operating system DLLs. It lets you build native Windows programs with the GNU GCC compiler.

MinGW64

Minimal GNU system for 64bit Windows. MinGW64 is not the MinGW project.

MrsP

Multiprocessor Resource-Sharing Protocol

MSYS2

Minimal System 2 is a fork of the MinGW project’s MSYS tool and the MinGW MSYS tool is a fork of Cygwin project. The Cygwin project provides a POSIX emulation layer for Windows so POSIX software can run on Windows. MSYS is a minimal version that is just enough to let configure scripts run. MSYS has a simplified path structure to make it easier to building native Windows programs.

NFSv2

Network File System version 2

OMIP

\(O(m)\) Independence-Preserving Protocol

OpenMP

Open Multi-Processing

POSIX

Portable Operating System Interface is a standard that lets software be portable between compliant operating systems.

prefix

A path used when building a package so all parts of the package reside under that path.

RFS

RTEMS File System

RSB

RTEMS Source Builder is part of the RTEMS Tools Project. It builds packages such as the tools for the RTEMS operating system.

RTEMS

The Real-Time Executive for Multiprocessor Systems or RTEMS is an open source fully featured Real Time Operating System or RTOS that supports a variety of open standard application programming interfaces (API) and interface standards such as POSIX and BSD sockets.

SMP

Symmetric Multiprocessing

Target

A target is the hardware or simulator a BSP built executable runs on.

Test Suite

See Testsuite

Testsuite

RTEMS test suite located in the testsuites/ directory.

TLS

Thread-Local Storage

Waf

Waf build system. For more information see http://www.waf.io/

YAFFS2

Yet Another Flash File System version 2
