The speed or efficiency of linux® is very good, but in some cases, such speed is not enough to meet the demand. What we need is the ability to meet scheduling deadlines within a specific tolerance range. This article will reveal various options for implementing real-time Linux and how they can be implemented in real time-from the architecture of the early imitation Virtualization solution to the choices ava
