Smartphone/tablet Systems-on-Chip (SoCs) integrate increasing number of components to offer more functionality. Capacity and efficiency of data communication between memory and other hardware blocks have become a major concern in the SoC design. To address this concern, we propose to use Network-on-Chip (NoC) architectures, to meet high bandwidth, and low power and area demands. We propose a Quality-of-Service (QoS) scheme to differentially provision network resources to cater to different performance requirements by different hardware blocks. Implementation and evaluation are performed on a simulation infrastructure we construct specifically for this type of SoCs. We demonstrate, via simulation results, that the proposed Dynamic QoS schemes can achieve better bandwidth provisioning, with good area and power efficiencies.
