PikeOS for MPU

Real-Time Partitioning for MPU Architectures

The PikeOS operating system is a lightweight virtualization system that is capable of hosting nearly all industry standard operating systems and execution environments. It supports the most stringent real-time requirements emerging from Safety-related industries, even on multi-core processor hardware.

The classic PikeOS depends on processor architectures that come with a Memory Management Unit (MMU). As a consequence, the available hardware is limited to boards with high complexity. This dependency has fallen and PikeOS is now available to lightweight systems that come with a Memory Protection Unit (MPU) only.

This member within the SYSGO product family is called PikeOS for MPU and opens the gates for a new range of controllers targeted to the Medical, Automotive, Aeronautics and Space industries. PikeOS for MPU reduces hardware requirements and complexity, yet easing and accelerating certification for Safety-critical systems.

Development Environment and APIs you have been used to...

Even more good news: There is almost no learning curve, as the development tools and API stay nearly identical. PikeOS for MPU is embedded into CODEO as if it was just another architecture. That also makes migration from older applications very simple. PikeOS Classic and PikeOS for MPU projects can even be managed in the same IDE at the same time.

More about CODEO

Since the development tools, such as the ROM-Image builder and the VMIT (Virtual Machine Initialization Table) builder, are shared between the two operating systems, PikeOS for MPU inherits the qualification status of its bigger brother. That together with the fact that PikeOS for MPU bases on SYSGO's well-proven virtualization technology, PikeOS for MPU comes with a head start in terms of certification.

PikeOS for MPU with SMP and AMP Architecture

Multi-core processors have entered the embedded market. However, unlike to desktop computing where all processor cores are of the same type, embedded SoCs (Systems-on-a-Chip) are highly specialized for a dedicated purpose. Therefore, you will often find heterogeneous processor cores on the same chip.

With the PikeOS family of products, you can manage the entire software stack of such a complex big SoC within one single CODEO workspace. The project wizards and editors support you while you are planning the architecture of AMP and SMP domains. Even anything in between can be designed. A typical setup on a Xilinx Ultrascale+ would look like as shown in figure 1: PikeOS running multiple partitions on the Cortex-A53 cores in SMP mode, while the Cortex-R5 cores are executing PikeOS for MPU in AMP mode.

During your development it might turn out that the current assignment of software applications to processor cores is not optimal. Fortunately, this can be fixed with almost no efforts, as the PikeOS solution allows you to utilize the same API, no matter whether the CPU provides an MMU or MPU.

PikeOS for MPU

Starting into the Multi-Core World

PikeOS for MPU is based on the same time- and resource partition management as the classic PikeOS operating system. It also shares the same internal, fine-grained locking mechanisms and has the same means to mitigate hardware interference between processor cores, e.g. due to cache contention. The system integrator has all methods at his disposal in order to determine the worst-case execution times and enforce that any application does not consume more processor usage than it is allowed. Together with our partner eco system, PikeOS for MPU is ready for Safety-related standards on multi-core processors, such as CAST-32A.

PikeOS in Space

Reducing Single Event Upset (SEU) Effects

The environment in space is harsh, not only in terms of temperature and vibration, but also due to cosmic radiation. One of the major goals is to reduce and mitigate the effects of a single event upset. That is why hardware for space missions is stripped down in complexity. Boards based on processors without an MMU are way less complex, easier to understand and better to protect. We are proud to say that one of the first projects and our motivation to build PikeOS for MPU lies in the support of Space missions.
