Abstract:

This paper presents a study on the various digital filers for the fault tolerance and error correction in DSP circuits. In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. The study puts a light on protection of the digital filters used widely i.e. fault-tolerant implementations based on the use of residue number systems or arithmetic codes have been proposed. The use of reduced precision replication or word-level protection has been also studied. Another option to perform error correction is to use two different filter implementations in parallel. All those techniques focus on the protection of a single filter.
