“…However, the scaling technology makes soft error dominate in the reliable NoCs [12,13,14,15]. Due to the increasing error rate and complex patterns of Multiple-Cell Upsets (MCU), the more and more concern on soft error also have received from the academic and industry [16,17,18,19]. Particularly MCU spoils the typical Error Correction Coding (SECDED, Single Error Correction Double Errors Detection) of Virtual Channels in NoC routers [20].…”

Approximate Network on Chip (NoC) is being considered as a good solution to reduce power consumption and improve the communication efficiency. However, increasing Multi-Cell Upsets (MCU) is seriously threatening the approximate NoC reliability and causes output far away from guaranteed quality of results. In this paper, we propose an unequal message protection framework with same coding length for mitigating MCU impacts on approximate NoC. The proposed framework makes good use of side information to select the special messages from normal messages and embeds same length coding scheme for all messages while providing stronger protection capability for special messages in approximate NoCs. The effectiveness of proposed methodology is evaluated by complete fault injection, which captures the dual-voltage approximate technique, unequal message protection mechanism and MCU error propagation in a joint manner. The cycle-accurate simulation using synthetic (e.g., Transpose, Uniform) and realistic benchmarks(e.g.,VOPD and MWD) show that, compared with the state-of-the-art approximate NoC architecture, the proposed unequal message protection framework can achieve up to average 84.9% reliability improvement with 6.25% power consumption 6.9% area overhead, and 15.38% latency increase.

Soft errors are transient errors caused by single-event effects (SEEs) resulting from a strike by high-energy particles acting on sensitive areas of integrated circuits. Soft errors frequently occur in the space environment, adversely affecting the reliability of aerospace-based computing. A recovery process is launched to recover the program when soft errors are detected. A periodic checkpointing recovery approach is widely utilized to prevent soft errors. However, this approach does not consider the detector locations, resulting in a large time overhead. This paper proposes a checkpointing recovery approach for soft errors based on detector locations called DLCKPT. DLCKPT reduces the time overhead by considering detector locations. The experimental results show that the percentage decrease in the time overhead between the DLCKPT and the periodic checkpointing recovery approach is 13.4%. The average recovery rate and average space overhead are 99.3% and 44.4% for the periodic checkpointing recovery approach and 99.4% and 34.6% for the DLCKPT. These results show that the DLCKPT and the periodic checkpointing recovery approach produce comparable results for the recovery rate. The DLCKPT has a lower time overhead and a slightly lower space overhead than the periodic checkpointing recovery approach, demonstrating its effectiveness.
