Embodiment Construction
[0038]In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0039] The present invention relates to a heterogeneous multi-core cache replacement algorithm based on lack of awareness. Taking a heterogeneous processor with two CPU cores and four GPU cores, each of which has its own L1Cache but shares one L2Cache, as an example, like figure 1 shown. The running CPU test program is single-threaded SPEC CPU2006, and the GPU application program is Rodinia. Each workload consists of a CPU test program and a GPU application program. In the simulator, the conformance protocol used is: X86_VI_hammer_GPU. In this protocol, the CPU and GPU have their own L1Cache and jointly access the L2Cache.
[0040] The present invention provides a heterogeneous multi-core cache replacement method based on missing perception. Fir...
