Abstract:

We propose link structures for NoC that have properties for tolerating efficiently transient, intermittent and permanent errors. The protection against transient errors is realized using Hamming coding and interleaving for error detection and retransmission as the recovery method. We introduce two approaches for tackling the intermittent and permanent errors. In the first approach, spare wires are introduced together with reconfiguration circuitry. The other approach uses time redundancy, the transmission is split into two parts, where the data is doubled. In both structures the presence of permanent or intermittent errors is monitored by analysing previous error syndromes. The links are based on self-timed signaling in which the handshake signals are protected using triple modular redundancy.
