Reconfiguration Aspects of PENCA - An Area-efficient Reconfigurable Encoder Architecture with Built-in Security Features for Flexible Error Detection and Correction in Robust Dependable Communication Systems

摘要

Communication technologies have experienced an explosive development during the last decades, and they are key and standard parts of most of today's integrated as well as field systems or new challenging industrial systems. As industrial robots are assumed to be real-time and safety-critical in combination, test- and error correction technologies have to meet all the new challenges. However, many existing technologies for error correction are not managing multiple faults, are too slow in terms of encoding and decoding, or lack other features required in order to satisfy industrial timing and general reliability constraints. This paper discusses reconfiguration aspects of our new programmable and reconfigurable PENCA architecture as the new concept towards dependable fully configurable systems, which promises a combination of reasonable overhead and relatively fast encoding, also ensuring a high level of dependability, while keeping important properties in flexibility, programmability and testability.
