P1-P2
Overview
Freescale OSEKturbo OS is the leading
OSEK/VDX™ Real Time Operating System
(RTOS) implementation available on the market
today in terms of quality and performance.
OSEKturbo fully conforms to the latest
OSEK/VDX Operating System standard
1
. The
RTOS is fully configurable and statically defined
within the CodeWarrior™ IDE environment. Only
those functions that are required are included
providing the user with a truly scaleable RTOS.
OSEKturbo OS is available for a wide range of 8-,
16- and 32-bit embedded microprocessors. The
emphasis in the design of OSEKturbo OS was to
meet demanding performance requirements, while
maintaining the outstanding reputation for stability
and quality (SEI CMM level 5
2
) established in
more than five years of automotive ECU
development. The result is that Freescale
OSEKturbo is one of most widely used
OSEK/VDX OS implementations on the market
today. Although the OSEK/VDX specification was
created by the automotive industry, the
specification does not limit its use to automotive
applications and it is increasingly being used in a
wide range of embedded applications ranging
from industrial control to telecom products.
Software Development Tools
Benefits
By adopting Freescale OSEKturbo
and CodeWarrior Development
Studio, embedded developers can:
> Reduce software integration time
and the associated costs
> Re-use software modules among
different application designs
> Reduce maintenance costs
through the use of a high-level
language and common platform
> Ensure a high-quality, stable
software environment for their
applications
> Ensure a highly efficient OS with
extremely small memory footprint
and outstanding performance
> Ensure an optimized, highly
integrated and broadly supported
development tool chain
OSEKturbo applications are written
in C language using the OSEK
Application Programming Interface
(API) enabling portability and re-
use of software.
REAL TIME OPERATING SYSTEM
Freescale OSEK tool support
Freescale offers a Builder tool for easy configuration
of OSEKturbo applications. The Freescale OSEK
Builder is a graphical Windows™ based application
that enables the developer to easily configure a
runtime system. The tool allows the developer to
optimize the software to meet the specific
application needs. A complete system description is
generated in OSEK Implementation Language (OIL)
format, allowing full portability of the application
configuration. The developer may also choose to
generate OS libraries from Builder.
Freescale also offers an OSEK plug-in to allow
kernel-aware debugging in CodeWarrior
Development Studio, enabling the developers to use
the CodeWarrior IDE for the whole application
development. It brings many advantages such as
simplified project setup through the use of
stationaries and samples. CodeWarrior tools support
Freescale’s 8- to 32-bit microcontrollers reducing
the number of tools that need to be re-learned for
new projects on different architectures. OSEK
System Generator (SysGen) is fully integrated in the
build process and for the configuration of project
settings. OSEK Builder can also be called as OSEK
configuration editor. CodeWarrior Development
Studio supports full OSEK OS kernel awareness
during debugging. CodeWarrior Development Studio
can also provide simulation support for development
without hardware.
In addition Freescale has established strong
partnerships with industry leaders providing
deeper integration with a wide variety of partner
tools including Model Based Simulation, Code
Generation, Schedulability Analysis, popular CAN-
based communications software and tools, and
support for many 3rd Party OSEK kernel aware
debuggers (emulators) and compilers.
