Randy Martin ranmartin@blackberry.com		Hypervisor Part 1- What is a Hypervisor and How Does it Work? A hypervisor allows multiple operating systems to share a CPU (or CPUs, in the case of multicore chips). While the basis of the technology is half a century old, the applications to embedded systems are new. In this whitepaper, we examine the underlying technology for, and some implementation details of, hypervisors specifically tailored for embedded systems. Read More... May 2016		Download

Grant Courville GCourville@qnx.com		Security Awareness In order for a system to be useful, it needs to interact with the environment and provide some level of functionality. Historically, embedded systems were mostly islands – that is, they provided their functionality in a stand-alone manner, and weren’t connected, or had limited connectivity to other systems. With these kinds of systems, it was relatively easy to analyze their security – the number of ways of getting in and compromising the operation was extremely limited. Read More...

Chris Ault cault@qnx.com		Total cost of ownership Linux vs. QNX - Part3 The Linux OS provides for open access to its source code. This has led some to choose Linux as a viable development platform, on the perceived basis that its cost is less than commercial alternatives. To examine this, we present a three-part whitepaper series that closely examines the total cost of ownership of Linux and how that compares to a commercial off-the-shelf realtime operating system like QNX. In Part 3 we examine the challenges of certifying a Linux-based system. Read More... February 2016		Download

Dennis Kelly dkelly@qnx.com		Breaking up is hard to do Contrary to the title, this paper is not about romance. It is about embedded software design and how to avoid professional heartache.It’s a fact of life – embedded systems need human interaction. With some systems, so much work is invested in the HMI that it’s easy to lose sight of the fact that the system exists for the purpose of performing work! This paper will deal with life-cycle issues of embedded systems requiring an HMI. Read More... February 2016		Download
