Error Detection in Fault Secure Controllers using State Encoding
Abstract
In applications where safety is of utmost importance, defective functions must frequently be detected very early in order to restore the system to a safe operating condition. At the same time the availability may not be restricted by measures implemented to detect errors. The efficiency of error detection state encodings for a control unit is investigated based on the example of the Motorola micro-processor core M68HC11. The terms "dependent encoding" and "independent encoding" are introduced. The designed circuits are compared regarding to error detection of stuck-at errors and chip area. The degree of error detection is shown with the help of a fault simulation.

Using Physical and Simulated Fault Injection to Evaluate Error Detection Mechanisms
PRDC '99: Proceedings of the 1999 Pacific Rim International Symposium on Dependable ComputingEffective error detection is paramount for building highly dependable computing systems. A new methodology, based on physical and simulated fault injection, is developed for evaluating error detection mechanisms. Our approach consists of two steps. ...
Encoding an arbitrary state in a [7,1,3] quantum error correction code
We calculate the fidelity with which an arbitrary state can be encoded into a [7, 1, 3] Calderbank-Shor-Steane quantum error correction code in a non-equiprobable Pauli operator error environment with the goal of determining whether this encoding can be ...
