Abstract

As continuous transistor scaling provides chip designers with billions of transistors, system architects have embraced multicore architectures to provide the exponential growth in performance. Interconnection has a remarkable influence on the performance when transferring a processor from single-core to multicore. This paper compares several popular interconnection structure used in current available productions, and select the crossbar switch as Longteng M2 quad-core processor´s interconnection mechanism. Simulation results show the implemented interconnection has speedup of 1.48-2.88 relative to Longteng R2 single-core processor.
