1. gem5 cache: 若采用gem5的classic缓存模型,是不支持多bank模式的,需自己配置。操作如下: src/mem/cache/ 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...

Creating a simple configuration script:通过写python配置文件,利用gem5基础组件搭建起一个简单的X86系统,并运行hello world仿真; Adding cache to the configuration script:本节继承并扩展了gem5自带的classic caches,并在简单的X86系统上加入了2级Cache,提高了程序执行效率; Understanding gem5 statistics and output:本...
