Abstract :
A split-bus architecture is proposed to improve the power dissipation for global data exchange among a set of modules. The resulting bus splitting problem is formulated and solved combinatorially. Experimental results show that the power saving of the split-bus architecture compared to the monolithic-bus architecture varies from 16% to 50%, depending on the characteristics of the data transfer among the modules and the configuration of the split bus. The proposed split-bus architecture can be extended to multi-way split-bus when a large number of modules are to be connected
