Current heterogeneous Chip Multi-Processors (CMPs) integrate a GPU architecture on a die. However, the heterogeneity of this architecture inevitably exerts different pressures on shared resource management due to differing characteristics of CPU and GPU cores. The authors consider how to efficiently share on-chip resources between cores within the heterogeneous system, in particular the on-chip network. Heterogeneous architectures use an on-chip interconnection network to access shared resources such as last-level cache tiles and memory controllers, and this type of on-chip network will have a significant impact on performance.
