Research Development of the Chip Multi-Processor Cache Management
Xuejun Yang · Computer Engineering and Science · 2010
It is important to design and manage the cache resources in a chip multi-processor.Currently,mainstream commercial CPUs share their last level cache while the performance of the last level caches has great impact on the CPU performance.Therefore,shared cache management becomes an active research area.In this paper,firstly,we introduce the design challenge of the CMP cache design and the processors from the mainstream vendors.Secondly,we put forward three key technologies of shared cache management:thread scheduling,NUCA and cache partitioning.Finally,we conclude our paper and point out the future trend of the CMP cache design and management.
