Reliable Services in an Imperfect World

Summary form only given. With the ongoing trends of hardware complexity - device density increases, reducing geometries, lower switching threshholds etc - hardware increasingly exhibits transient faults. Software is not perfect and the increasing complexity results in Heisenbugs. Consequently it becomes a complex technological challenge to build dependable embedded systems that can accommodate and mitigate these facts of hardware and software transients such that the user perceived services are not seriously impacted.
