Akita
Akita is a computer architecture simulation engine. Like a game engine, a simulator engine is not a simulator, but rather a framework for building simulators. Akita is designed to be modular and extensible, allowing for easy experimentation with new computer architecture design ideas.
Sub-Projects
Akita
The simulator engine itself is located under the packages including:
github.com/sarchlab/akita/simgithub.com/sarchlab/akita/pipelininggitlab.com/sarchlab/akita/analysis
AkitaRTM
AkitaRTM stands for Real-Time Monitoring (RTM) tool for Akita. It is a web-based tool that can be used to monitor the execution of a simulator developed with Akita. It is located under the github.com/sarchlab/akita/monitoring package.
Daisen
Daisen is the visualization tool for Akita. It is located under the github.com/sarchlab/akita/daisen package. For a brief introduction to Daisen, please refer to the github.com/sarchlab/akita/daisen directory.
First-Party Components
Akita provides several generic first-party components that can be used to build simulators, located under the github.com/sarchlab/akita/mem and github.com/sarchlab/akita/noc packages. As the name suggests, the mem package contains memory components (e.g., caches, TLB, DRAM controller), while the noc package contains network-on-chip components (e.g., switches).
