Abstract :
In this paper, we propose evaluation flow for estimating the performance degradation of motion estimation (ME) architectures when faults occur and decide their acceptability. Moreover, when a fault is evaluated as unacceptable, a swap-based error-tolerance (ET) technique is proposed to increase the acceptability of this fault. According to experimental results, the acceptability and effective yield can be improved significantly with negligible hardware overhead.
