Eclipse Plugin for MMIX
This Sourceforge project is dedicated to providing an Eclipse-Plugin
for Donald
E. Knuth's famous MMIX-Processor.At
the moment it contains only a visualisation of the pipeline contents as it can
be shown with the configurable meta-mmix-simulator. It is kind-of similar to
that one used by Don Knuth in his Computer Musing on "MMIX:
A RISC Computer for the New Millennium".
I started developing since I needed such an animation for educational purposes.At
the moment it is not really user-friendly!
Documentation will hopefully come soon.
Requires Eclipse Version 3.1 and Java Version 5.0
You need the GEF/draw2D plugin as prerequisite.
This site (mmix-plugin.sourceforge.net) can be used as an Eclipse-Updatesite
as well.
To run the visualisation you need to have a running copy of mmmix (mmmix.exe
on Windows) in your path.
- Open the MMIX-perspective.
- Create a simple project where an .mmb-file is located. Create a configuration
(New->Simple->File) with extension "mpe". Edit and save the
configuration (via button on the Overview tab of the configuration editor
that is associated with the extension "mpe"). Right-click on the
.mmb-file and select "LaunchMMB File" from the context menu. You
also can use my experimental configuration for the PPC970
here.
- In the activity view at the bottom you can double click to any cycle you
like and see the contents of the pipeline. There is a control window that
allows you to proceed a defined amount of clock cycles. The color coding is:
blue for stalled instruction, yellow
for instructions that are currently executed; green
for instructions that are already finished and are waiting for commit; and
finally red for instructions that have to be
deissued (e.g. after mispredicted branches). The activity view indicates the
number of instructions in the respective state as well as state of memory)
- You need to double click several times in the activity view until all elements
are on their places (I don't know how to change this behavior).
Screenshot to be seen here.
