Sigma17 is a re-write of the original emulator written by John O' Donnell. The overall aim of Sigma17 is to re-write the entire web based app but keep apps functionality. This is so that it is easier and more intuitive to code in Sigma16 with the web based app.
Sigma16 is a computer architecture designed for research and teaching in computer systems. This application aims to provide a complete environment for experimenting with the architecture.
Currently, the emulator can be used by visiting the Sigma17 website which is hosted by github as a github.io project site and is kept up to date with all major changes.
Also, the emulator can be ran locally using npm and React.js from the source directory which will support more minor changes that will not effect the overall ability of the github.io site.
Visit the website.
The following software needs to be installed in order to build the local server :
node.jsnpm
After these are installed, to compile the program, execute the following commands in the repository directory:
npm install
npm startThis will start the local React.js development server and should open a window in your default browser to localhost:3000, in which the website can be used as normal.
