Implementation of delay-insensitive (DI) or unordered codes is the subject of this report. We present two diierent architectures for decoding systematic DI codes: (a) enumeration-based decoder, and (b) comparison-based decoder. We argue that enumeration-based decoders are often impractical for many realistic codes. Comparison-based decoders that detect(More)
Digital filters when implemented with very dense high-speed electronic devices are susceptible to both temporary and permanent failures, not easily protected by conventional fault-tolerant computer design principles. A new method is presented for protecting the overall realization against both hard and soft errors at the data sample level using the(More)
