Abstract

This paper presents scheduling techniques for small embedded system. The main contribution of the work is related to the way in which the kernel is organized to schedule and dispatch tasks. This is done based on special data structures that allow a very fast search of the next higher priority task ready to execute. This is achieved without producing a significant increment on the amount of memory required to implement the mechanism and at the same time keeping the footprint smaller than other kernels.
