A column parity based fault detection mechanism for FIFO buffers
2013
Integration
This paper presents a low cost fault detection mechanism for FIFO buffers. The scheme is based on column parity maintenance in a single register, which is updated by monitoring the values written to and read from the FIFO memory array. A non-zero column parity when the FIFO is empty, constitutes an indication of fault, and this property is exploited for fault detection. The technique has gains in area, power and critical path delay, at the expense of (1) greater detection latency, due to the
