【 摘 要 】

References(12)A low-power bus coding called Green Phase Difference Coding (GPD) is proposed to reduce the power consumption of long interconnects between multi-cores. In GPD, the Green-Modified coding (GM) is a novel low switching activity coding on the basis of Self-Corrected Green Coding (SGC). The mapping of GM coding between original set and converted set is modified to reduce bit transition. And the phase difference technology that uses the phase difference between the clock and data is introduced to replace decision bit. Based on SMIC 130 nm CMOS technology, the simulation results show that the GPD coding scheme achieves 37.51% and 4.13%�?8.29% energy reduction compared with the parallel bus by applying random data source and SPEC95/2000 CINT reference source, respectively.
