Chapter6 2 6. Combined Crosstalk Avoidance Code with Error Control Code for Detection and Correction of Random and Burst Errors

Abstract Error correction codes are majorly important to detect and correct occurred errors because of various noise sources. When the technology is scaling down, the effect of noise sources is high. The coupling capacitance is one of the main constraints to affect the performance of on-chip interconnects. Because of coupling capacitance, the crosstalk is introduced at on-chip interconnecting wires. To control the single or multiple errors, an efficient error correction code is required. By combining crosstalk avoidance with error control code, the reliable intercommunication is obtained in network-on-chip (NoC)-based system on chip (SoC). To reduce the power consumption of error control codes, the bus invert-based low-power code is integrated to network interface of NoC. The advanced work is designed and implemented with Xilinx 14.7; thereby the performance of improved NoC is evaluated and compared with existing work. The 8×8 mesh-based NoC is simulated at various traffic patterns to analyze the energy dissipation and average data packet latency.
