Adaptive error control for reliable systems-on-chip

We present an adaptive error control scheme that employs a link quality grading technique and a burst error prediction mechanism, in order to handle multi-wire and multicycle errors, respectively. Our approach enables the transmitter to select the most effective error-control scheme for the particular link quality. Using this method, we can improve switch-to-switch throughput by 4X and reduce power consumption by 70%, compared to retransmission-only and retransmission-plus-fixed-coding approaches.
