gem5、McPAT和HotSpot的聯合模擬實驗教程

1. Gem5
Gem5由C++和
Python共同完成。可以在FS（full system）模式下模擬完整的系統，或是在SE（syscall emulation）模式下由模擬器提供系統呼叫模擬使用者空間程式。
1.1 Gem5的安裝
1.1.1 預裝軟體
（1）安裝python
因為scons是用python寫的，所以在使用scons之前，我們需要安裝python。一般情況在你安裝的系統中都已經有python，可以使用：
python -V或者
python –version
至此，gem5、McPAT和HotSpot的聯合模擬就結束了。 參考： http://blog.csdn.net/caoyahong114/article/details/50955732
sudo apt-get install scons
sudo apt-get install g++
sudo apt-get install python-dev
sudo apt-get install libprotobuf-dev
sudo apt-get install libgoogle-perftools-dev1.1.2 編譯Gem5 到 http://repo.gem5.org/或者 http://download.csdn.net/detail/u013541140/9568720下載gem5-stable，解壓到gem5裡，重新命名為gem5-stable，然後執行下列命令：./configure make sudo make install
cd /home/jimmy/gem5/gem5-stable
mkdir build

info: Increasing stack size by one page.
Hello world!
hack: be nice to actually delete the event here
