Abstract

Cache, as the hub between the multi-core processor and the memory, is closely related to the performance of the CMP system. And with the number of processor core increasing, the contention of multi-core for shared cache becomes more intense. Fairness is important to affect the performance of CMP systems, so a Shared Cache allocation method based on fairness is proposed. According to the way of borrow-return, the method assigns Shared Cache to multiple to realize the dynamic balance. The experimental results show that the method significantly improves the system fairness and the system throughput.
