gem5 研究概况

开始分析gem5的原理和实现。这里只是收集一些gem5的网页，研究的一些分类等等。

1，doc

gem5的在线Doxygen 的 doc ： http://www.gem5.org/docs/html/index.html

gem5 Tutorial  : http://learning.gem5.org/book/

学习网站：   http://learning.gem5.org/tutorial/index.html

比较全面的介绍m5 模拟器： http://www.m5sim.org/dist/tutorials/asplos_pres.pdf

2，gem5和gpu

http://www.gpgpu-sim.org/

https://gem5-gpu.cs.wisc.edu/wiki/

http://research.cs.wisc.edu/multifacet/papers/cal14_gem5gpu.pdf   (很好的gem5-gpu的介绍论文)

Gem5的GPU 源码：https://github.com/gem5-gpu     （这是wisc 搬移过来的网站）

http://gem5.org/GPU_Models

https://blog.csdn.net/junning_wu/article/details/52279783   （CPU+GPU仿真模型：gem5 & GPGPU-Sim）

http://www.m5sim.org/GPU_Models

A NoMali GPU model. gem5 comes with an integrated NoMali GPU model that is compatible with the Linux and Android GPU driver stack, and thus removes the need for software rendering. The NoMali GPU does not produce any output, but ensures that CPU-centric experiments produce representative results:

Gem5的编译采用 --ggdb3的选项，提供了更多的可调试信息。

4，微操作，微融合研究

   gem5具备微操作和微融合：其中一些相关网站的链接：https://blog.csdn.net/weixin_34192993/article/details/87435562

   http://gem5.org/X86_microcode_system，

  https://dendibakh.github.io/blog/2018/02/15/MicroFusion-in-Intel-CPUs

  https://www.agner.org/optimize/microarchitecture.pdf

https://easyperf.net/blog/2018/02/04/Micro-ops-fusion

http://flyspray.gem5.org/Microcode_assembler

gem5中有microcode， macro code，但是没找到fusion。

《Mobilizing the Micro-Ops: Exploiting Context Sensitive Decodingfor Security and Energy Efficiency》关于微操作的一篇ISCA2018的论文，可以参考。

5，gem5 NOC 片上网络模拟
