When the input signal has been interfered and glitches occur, the power consumption of Double-Edge Triggered Flip-Flops (DETFFs) will significantly increase. To effectively reduce the power consumption, this paper presents an anti-interference low-power DETFF based on C-elements. The improved C-element is used in this DETFF, which effectively blocks the glitches in the input signal, prevents redundant transitions inside the DETFF, and reduces the charge and discharge frequencies of the transistor. The C-element has also added pull-up and pull-down paths, reducing its latency. Compared with other existing DETFFs, the DETFF proposed in this paper only flips once on the clock edge, which greatly reduces the redundant transitions caused by glitches and effectively reduces power consumption. This paper uses HSPICE to simulate the proposed DETFF and other 10 DETFFs. The findings show that compared with the other 10 types of DETFFs, the proposed DETFF has achieved large performance indexes in the total power consumption, total power consumption with glitches, delays, and power delay product. A detailed analysis of variance indicates that the proposed DETFF features less sensitivity to process, voltage, temperature, and Negative Bias Temperature Instability (NBTI)-induced aging variations.

There is a sharp decline in the network performance when the wireless link fails as a data path in the Wireless Network-on-Chip (WiNoC). To counteract this problem, we propose a fault-tolerance mechanism for the efficient retransmission of data in the WiNoC. When an error is detected in the data transmission process, this mechanism works to feed back the fault information to the source node in real time via fault signal lines. In the source node, the highest transmission priority is assigned to the backup retransmitted data, and the corresponding direct link is positioned to enable the data packet for its efficient retransmission to the destination node, thereby ensuring efficiency in fault tolerance. Additionally, we have improved the receiving port of the wireless router, added the corresponding redundant buffers and mux, and dynamically selected the retransmitted non-faulty data packets to be written to the local router in order to avoid the disorderly retransmission of the data packets. The evaluation results of this paper demonstrate that compared with the methods which are under different fault conditions, this fault-tolerant method drastically improves the data throughput rate, reduces the delay, effectively guarantees the reliability of the network, and improves the system performance.
