Safety SCIOPTA IEC61508 SIL3 Safety Certified Real-Time Kernel

The SCIOPTA real-time kernel is in the final stages of certification by TÜV Germany to the IEC 61508 standard at Safety Integrity Level 3 (SIL3).
The first SCIOPTA safety certified kernel will be available for the ARM®7/9 target platforms. Support for other processors such as PowerPC, ColdFire® and XScale is planned.

IEC61508 is an international standard focusing on safety-related systems that incorporate electrical, electronic and/or programmable electronic (E/E/PE) instruments and devices.

Initially mainly used in the automation and process control industry, IEC61508 is more and more accepted for applications in other industries including automotive and medical where safety and reliability are paramount.

SCIOPTA safety documentation includes the Safety Manual, the TÜV IEC61508 SIL3 certificate and the TÜV certification report. All other certification documents such as Safety Requirement Specification, Design Specifications, Test Specifications, Safety, Validation and Verifications Plans are available upon request.

Technology

SCIOPTA 61508 is a pre-emptive multi-tasking high performance real-time kernel which includes many built-in safety features.

As a direct message-passing kernel, SCIOPTA is very well suited to be used in safety-critical applications.

No Shared Memory

Shared memory is the standard method for interprocess communication in traditional real-time operating systems. The user is fully responsible to protect shared memory with semaphores and to associate semaphores with data areas and types.

There is no need for shared memory in a SCIOPTA system. Direct message passing is safer. All data is encapsulated inside messages and the kernel protects message data by controlling ownership.

Safe Memory Management

Processes can be grouped together into SCIOPTA modules. Each module can have up to 128 pools to hold SCIOPTA messages.

SCIOPTA supports a module friend concept. Friendship between modules can be defined and configured by the user. This friendship setting defines if messages are copied or not when they are crossing module boundaries.

Modules and pools can be located in the same or in different memory segments. With the SCIOPTA Memory Management System (SMMS) and a Memory Management Unit (MMU) full memory protection can be achieved.

PXA270 SCIOPTA System Software ported to PXA270

SCIOPTA Systems AG is announcing the immediate availability of the SCIOPTA Real-Time Operating Systems for the INTEL PXA270 processor.

The SCIOPTA PXA270 RTOS is written in highly optimized assembler and specifically tuned for the PXA270 processors. This results in a very high performance and a low memory footprint.

SCIOPTA is fully dynamic. All system resources such as modules, processes and message memory pools can be created and killed during run-time.

Beside the fast Real-Time Kernel there is IPS (Internet Protocols, TCP/IP), IPS Applications (Web Server, DHCP, DNS, SMTP, Telnet, TFTP etc.), SFFS (Flash File Systems), USB support, embedded GUI graphics support and the DRUID System Level Debugger available.

SCIOPTA is royalty free and supports actually the C/C++ compilers and environments from GNU GCC and ARM RealView. A precompiled version of GCC is included on the SCIOPTA CD.

Intel PXA270 Processor

Today's embedded applications demand a unique set of features, packaging, product life cycle and performance. Because Intel solutions deliver key technologies that help drive functionality to new heights, the Intel® PXA270 processor is designed to meet the growing demands of a new generation of leading-edge embedded products. Featuring advanced technologies that offer high performance, flexibility and robust functionality, the Intel PXA270 processor is packaged specifically for the embedded market and is ideal for the low-power framework of battery-powered devices.

Product Highlights

The Intel PXA270 processor is the first Intel XScale® technology-based processor to include Intel® Wireless MMX™ technology. This enables high-performance multimedia acceleration with an industry proven instruction set.

Another innovative feature is the Intel® Quick Capture technology, which provides one of the industry's most flexible and powerful camera interfaces for capturing digital images and video.

The new capabilities of Wireless Intel SpeedStep® Power Manager technology provide a quantum leap forward in low-power operation, while maintaining the highest levels of performance.

Castle Litronic AG becomes SCIOPTA Systems AG

Bottmingen / Basel (Switzerland) - based Litronic AG announced that effective today, the company's name will become SCIOPTA Systems AG in order to align itself more closely with its core real-time software business.

We believe that SCIOPTA Systems AG better identifies us and our business developing, marketing, selling and supporting the SCIOPTA real-time software products, " Roland Lips CEO and president of SCIOPTA Systems AG said. " The name change is a strategic move designed to clearly align the company with its branded line of business offering real-time operating systems (RTOS), networking software, file systems, USB software and real-time test and debugging tools".

About SCIOPTA

SCIOPTA Systems develops, sells, supports and maintains systems software for safety-critical embedded applications.

This includes real-time operating systems, network software, file systems, software for interface bus systems, board support packages and other system software.

SCIOPTA is a message based real-time operating system with many built-in safety functions and is therefore very well suited for software forming part of safety-related systems. SCIOPTA is in the process of certification by TÜV to IEC61508 at Safety Integrity Level 3 (SIL3).

But SCIOPTA is more than just an RTOS. It is a new and modern approach to design embedded systems. The direct message passing method allows easy and time-saving design of robust and secure systems. Applications based on the SCIOPTA Method can cover small static SoC designs to large dynamic distributed systems.
