Fetch操作是在CU的SIMD单元之间共享和仲裁的。在同一个CU内,SIMD共享和仲裁fetch的权限,并将数据发配到每个WF的cache line。 在gem5里,每个SIMD可处理10个WF,一个CU里有4个SIMD。一共是40WFs。WF的contexts包含自己的pc和decoded instruction buffers,时序上需要4个cycles才能完整运行一个simd指令。 Scoreboard: sco...
a.【src/mem/cache/Cache.py】cache 的声明源代码:定义了cache的基本参数,以及三个文件:cache.hh, base.hh, noncoherent_cache.hh; 在该文件中添加:enable_bank_model, num_banks, bank_intlv_high_bit classBaseCache(ClockedObject): type='BaseCache'abstract=True cxx_header="mem/cache/base.hh" size=...
使用--cache参数是因为默认使用的CPU model是O3和minor,需要cache才能工作。使用--dvfs参数使能dvfs_handler,最后通过命令行方式分别设置大小核的电压-频率对。 > cd your/gem5/main/directory > build/ARM/gem5.opt \ --debug-flags=dvfs_handler,EnergyCtrl \ --debug-file=dvfs_debug.log \ configs/example/...

以下是一个gem5代码示例,演示如何在CPU模拟中添加L1-Dcache和DSB缓存: from m5.objects import * class MyCPU(FaultModelCPU): def __init__(self): super(MyCPU, self).__init__() self.clk_domain = SrcClockDomain() self.clk_domain.clock = '1GHz' ...

The fastmodel support has been improved to function with Linux Kernel 5.x. The set_se_binary_workload function now allows for the passing of input parameters to a binary workload. A functional CHI cache hierarchy has been added to the gem5 Standard Library: "src/python/gem5/components/cache...
