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

What is SR-IOV and Why is It Important for embedded devices?

Single Root I/O Virtualization (SR-IOV) is the complex name for a technology beginning to find its way into embedded devices. SR-IOV is a hardware standard that allows a PCI Express device – typically a network interface card (NIC) – to present... Read More
