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

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

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

Lynx & ENSCO Demonstrate Avionics Solutions at DSEI JAPAN 2019

The most formidable challenges of modern avionics development programs are often centered around the safety certification process and the corresponding requirements and costs. Equally as challenging to any large development program are the design... Read More
