Employing Two 'Sandwich Delay' Mechanisms to Enhance Predictability of Embedded Systems Which Use Time-Triggered Co-Operative Architectures

In many real-time resource-constrained embedded systems, highly-predictable system behavior is a key design requirement. The “time-triggered co-operative” (TTC) scheduling algorithm provides a good match for a wide range of low-cost embedded applications. As a consequence of the resource, timing, and power constraints, the implementation of such algorithm is often far from trivial. Thus, basic ...

Ways for Implementing Highly-Predictable Embedded Systems Using Time-Triggered Co-Operative (TTC) Architectures

Embedded system is a special-purpose computer system which is designed to perform a small number of dedicated functions for a specific application (Sachitanand, 2002; Kamal, 2003). Examples of applications using embedded systems are: microwave ovens, TVs, VCRs, DVDs, mobile phones, MP3 players, washing machines, air conditions, handheld calculators, printers, digital watches, digital cameras, a...

Implementing adaptive time-triggered co-operative scheduling framework for highly-predictable embedded systems

For many real-time embedded systems, Time-Triggered Co-operative (TTC) scheduling algorithms provide simple and reliable solution at low cost. Previous work in this area has focused on the development of a wide range of TTC implementations for various purposes (e.g. for achieving low-jitter characteristics, reducing CPU power consumption or dealing with task-overruns). Despite the great deal of...
