This project is an attempt to redesign, as a web application, all the features of the famous y86 pedagogical computer architecture teaching environment. It manages sequential and pipe-lined processors, both for 32 and 64 bit word sizes.

Context

The original y86 environment is a Tcl/Tk-based pedagogical tool created by Randal E. BRYANT et David R. O'HALLARON in the context of their course Computer Systems: A Programmer's Perspective.

Because of its simplicity and pedagogical efficiency, this tool has been widely adopted worldwide by the computer architecture teaching community. Yet, as its underlying technologies and design began to obsolete, several me-too's have been created using, notably, web technologies.

At Université de Bordeaux, we used for some time a web-based version of the tool for y86 programming and execution, but still relied on the initial Tcl/Tk version of the tool for HCL programming and processor design. For the sake of simplicity and in order to provide students with a consistent and integrated framework for processor design and machine code execution, we decided to launch a project to create a web-based version that would comprise the HCL part as well.

The specifications of the new tool have been provided in 2020 to a team of four students of the Projet de Programmation informatics Master 1 course at Université de Bordeaux. Several subsequent teams and interns contributed further to the development of the tool, which is now fully functional and used for teaching.

Minor issues may remain. Further contributions are always welcome!
