On reference architectures

By LYNX Software Technologies on Jan 8, 2021 11:57:36 AM

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 “overall design of a computing system and the logical and physical interrelationships between its components” is intuitively obvious. The fact that the architecture specifies the hardware, software, access methods and protocols used throughout the system comes as a surprise to no-one.

What Is A Separation Kernel?

By Tim Loveless | Principal Solutions Architect on Mar 22, 2020 12:02:33 PM

_______________

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, safety, reliability, and adaptability impact on complex system designs. Yet despite providing strong security and safety benefits and being the foundation of some of the world’s largest mission-critical systems, separation kernels remain largely unknown and poorly understood. In this article, we hope to:

  1. Bring some clarity to the topic of separation kernels vs. real-time operating systems (RTOSes) and embedded hypervisors
  2. Discuss the benefits and drawbacks of using a separation kernel as the software foundation of your embedded systems design
  3. Introduce LynxSecure®, our own separation kernel
