Back in early November 2001, I started following a discussionbetween two factions of the Linux kernel community. The gist of thediscussion was over what was the best solution to the Linux ...

Hard real-time Linux has been around for ages, or it may never appear. It all depends on who you talk to. It also depends on your requirements. A two-second interrupt latency may be acceptable for ...

Abstract: Interrupt handling with predictably low latency is a must for systems to respond to external events. System designers of tiny embedded computers to large-scale distributed systems face the ...

The success of Linux as a desktop operating system, and the appeal of its open source technology, might provoke one to dream of applying it to embedded systems. After all, embedded systems run on the ...

Linux was originally written as a general-purpose operating system without any consideration for real-time applications. Recently Linux has become attractive to the real-time community due to its low ...

Abstract: In real-time operating systems, timer interrupts are usually used for indicating when a real-time task should be started. Critical sections with interrupts disabled can, however, cause an ...

Linux has become well-established in the world of embedded design, but there are often reservations about its real-time performance. There are significant advantages to using Linux. A careful analysis ...

Performance measurements come in two flavors, throughput and latency. The former is like the width of an expressway: the wider the expressway, the more cars that can travel on it. The latter is like ...
