Abstract


In the process and the application of double promotion , on-chip multi-core processors become the development trend of the current high-performance microprocessors . Multi checklist chip Cache, bandwidth and storage resources , competition will further highlight the memory access bottleneck , accompanied by a variety of target applications , performance evaluation study of micro- architecture environment facing new requirements . This study focused on multicore processors , memory hierarchy - NUCA performance optimization of the structure and performance of multi-core processors simulation technology start work covers two aspects of structured logic design and simulation platform construction . In order to alleviate the pressure of more than check the memory access , multi-core processors commonly used in large -capacity on - chip Cache way to improve the performance of storage systems . Management of large -capacity on-chip Cache the NUCA technology , improved NUCA structure search strategy for multicore processor chip . Existing search strategies or suffer significant performance loss or excessive storage space requirements . In this paper, the strategy is based on the Bloom Filter is a complexity of effective search mechanism , effective use of the number of transistors and do not need to change the basic coherence protocol . It reduces the storage requirements of multi-core processors NUCA structure and its performance has also been improved , guiding significance for future work . With the development of the processor architecture and the emergence of new applications , the use of full system simulation is the inevitable trend of the future micro- architecture studies . This paper studies the multi-core processors in the system-wide environment simulation technology , a detailed analysis of the realization of the multi-core full system simulator GEMS NUCA model the GEMS build improved feasible performance simulation and evaluation environment for multi-core processors research .
