| Research Abstract |
The objective of this study is to establish a novel on-chip memory architecture that can provide necessary memory resources to running applications under the consideration of their behaviors and requirements regarding a memory subsystem on a multi-core processor.
In this study, we have developed a cache-resource management mechanism to realize energy-efficient high performance execution of multi-threaded applications on a multi-core processor. In cooperation with developed hardware functions of cache resizing and partitioning to reduce cache conflicts and maximize the efficiency of cache utilization, this mechanism can extract the potential of multi-core processors with a low-power consumption.
