As embedded applications in the Aerospace, Automotive and other industries do mostly rely on multicore processors today, SYSGO has optimized multicore support in the new PikeOS version 4.2 a hard real-time operating system (RTOS) with hypervisor and separation microkernel The new release has been designed specifically for systems and applications that need certification according to safety or security standards such as DO-178B/C, EN 50128, ISO 26262, as well as Airbus SAR and Common Criteria requirements.
In PikeOS 4.2, SYSGO has vastly improved application performance in multicore environments. A fine granular kernel locking that enables all cores to continue their processes even while one of them executes a system call, greatly reducing unproductive processor cycles. Other cores may only be blocked, if they attempt to access the exact same resource in order to control interference. PikeOS 4.2 therefore fulfills an important prerequisite for support of the latest ARINC-653 multicore standard.
PikeOS 4.2 also improves the energy efficiency of embedded systems as it allows the developer to manage multiple hardware clock devices and frequencies on the same board – including System on Chip (SoC) internal and external clocks. This way, applications as well as IPs on the SoC can easily be stopped and restarted as needed, reducing both resource and energy consumption.
In order to greatly reduce effort, time and thus money to have an embedded system certified according to various standards, SYSGO has created a consolidated environment for workflows and documentation of all processes including the build process. This also allows to integrate applications into customer build environments. “Being the leading European operating system manufacturer, we have a long track record in supporting our customers in the entire certification process”, said SYSGO’s VP of Marketing & Product Strategy, Franz Walkembach. “With PikeOS 4.2, these customers have now access to a software platform that has been strictly designed with certification in mind. What is more – they will also benefit from an entire ecosystem around this platform which brings together the expertise of SYSGO, our partners and the scientific community.”
PikeOS 4.2 has made its debut during the embedded world 2017 conference and will be available in April 2017. The new release supports a wide range of multicore CPUs, including ARM v7 and v8, 32 and 64 bit PowerPC and 32 and 64 bit x86. Board Support Packages (BSPs) are available for a wide selection of silicon vendors like NXP/Freescale, Renesas, Intel, Xilinx and Altera.
The first product based on PikeOS 4.2 will be SYSGO’s own safety and security certification kit that will enable customers an efficient safety or security certification kick-off element. Therefore helping to reduce time spent during long certification programmes.
PikeOS 4.2 provides a modern compact and certifiable Hypervisor technology with separation microkernel, implementing robust time and resource partitioning, which allows interference channels to be managed within your certifiable project. In addition, PikeOS 4.2 provides another dimension to the time schedules of individual resource partitions by core, where direct CPU affinity may be used to implement core separation for ultra critical partitions to be managed with PikeOS.
