PURE Embedded Operating Systems—CiAO

The increasing complexity of embedded systems calls for operating systems that are highly specialized and at the same time are made of a number of reusable building blocks. This brings up a conflict as software specialized in supporting a very dedicated case usually cannot be (easily) reused for a different environment. As described in the paper, supporting specialization without abandonment of...

Embedded Systems and Real Time Operating Systems

Most embedded systems are small enough to sit on the end of your thumb and are usually hidden within much larger and more complex mobile computing or electronic devices, so they often go unnoticed. But embedded systems actually represent the vast majority of semiconductor sales. According to the World Semiconductor Trade Statistics blue book, there are an estimated 5 billion embedded microproce...

Dynamic Configuration of Embedded Operating Systems

Traditionally, configuration of operating systems is done statically at compileor link-time, but recently dynamic runtime configuration has become possible. Embedded systems however have constraints, such as limited memory and real-time requirements, that prevent many dynamically configurable operating systems from being used in an embedded system. This paper describes efficient dynamic loading...

Real-Time Operating Systems: The Next Stage in Embedded Systems

A real-time operating system (RTOS) is an operating system (OS) intended to serve real time application requests. It must be able to process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter. Real-time operating systems have evolved over the years from being simple executives using cyclic s...
