Abstract
A real-time operating system kernel, called the Spring kernel,
that provides some of the basic support required for large, complex,
next-generation real-time systems, especially in meeting timing
constraints, is presented. The approach meets the need to build
predictable yet flexible real-time systems. Most current real-time
operating systems contain the same basic paradigms found in time-sharing
operating systems and often use a basic priority-scheduling mechanism
that provides no direct support for meeting timing constraints. Spring
uses two criteria to classify tasks' interaction with and effects on the
environment: importance and timing requirements. Implementation
experience with Spring is described
