Abstract :
In this paper, a low power joint bus and error correction coding is proposed to provide reliable and energy- efficient interconnection for network-on-chip (NoC) in nano- scale technology. The proposed self-corrected ";green"; (low power) coding scheme is constructed by two stages, which are triplication error correction coding (ECC) stage and green bus coding stage. Triplication ECC provides a more reliable mechanism to advanced technologies. Moreover, in view of lower latency of decoder, it has rapid correction ability to reduce the physical transfer unit size of switch fabrics by self- corrected technique in bit level. The green bus coding employs more energy reduction by a joint triplication bus power model for crosstalk avoidance. In addition, the circuitry of green bus coding is more simple and effective. Based on UMC 90 nm CMOS technology, the simulation results show self-corrected green coding can achieve 34.4% energy reduction with small codec overhead. This approach not only makes the NoC applications tolerant against transient malfunctions, but also realizes energy efficiency.
