Single Root I/O Virtualization (SR-IOV) -Pt 2- LynxOS-178 10G network benchmarkS

_______________ Single Root I/O Virtualization (SR-IOV) virtualizes network interface cards (NICs) to allow a single NIC to present itself as dozens of virtual NICs to a hypervisor. It is a hardware standard, part of the PCI-SIG (Peripheral... Read More

Who Needs a Hypervisor?

_______________ The standard benefits of a hypervisor are well known and often touted. Every RTOS has its hypervisor and they do genuinely help embedded designers to: Partition multicore processors into virtual machines; an elegant way to... Read More

Edge Computing is Here. What's Next?

_______________ Industry 4.0? Edge computing? Call it what you will, the fact remains that our industry moves slowly. Obstacles must be overcome before we can claim that edge computing has evolved from theories and experiments to true industrial... Read More

What is Cache Coloring and How Does it Work?

_______________ There are substantial challenges in building secure and safe systems on multicore processors (MCPs). Last level cache contention is undoubtedly the largest source of multicore interference, and a significant challenge for real-time... Read More

On reference architectures

What is a reference architecture? The term “architecture” seems to be in ever increasing use in its technological context. As an extrapolation from the construction term that Frank Lloyd Wright would have been familiar with, its definition as the... Read More

What Is A Separation Kernel?

_______________ Having built both separation kernels and real-time operating systems—and supported customers using both across a wide range of industries—we are familiar with the pros and cons of each software technology, as well as their security,... Read More

TC-16/51: Adding Bottom Up Interference Analysis for MCPs

_______________ I hadn't heard of "bottom up" avionics certification before I read FAA's TC-16/51. But now, looking back at it, I think the authors from Thales Avionics, including Xavier Jean, PhD, proposed a big change in perspective. In their own... Read More
