SYSGO optimizes multicore support and energy efficiency in PikeOS 4.2
SYSGO has optimized multicore support in the new PikeOS version 4.2, a hard real-time operating system 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.
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 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.
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 are available for a wide selection of silicon vendors like NXP/Freescale, Renesas, Intel, Xilinx and Altera.
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.
