While old, it is sufficient “simple” to allow us, in the time available, to gain experience on how to explore architectural options.

Most of the changes will happen in ruu_issue which is the function that simulates the OOO scheduler using register dependencies. We will overview how it works during the lectures. text/html 2019-01-20T01:19:57+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.eecg.toronto.edu/~moshovos/000/doku.php?id=wiki:aca2019:cygwin32install&rev=1547947197&do=diff Installing CYGWIN 32b You will need this if you plan to use the Simplescalar compiler tools we are providing.

All require that you submit a written proposal by March. 21st online. * Propose your own topic. * Pick a recent paper from a top-tier architecture conference and validate part of its results. You may choose to validate one of the papers that were discussed in the course. I will provide suggestion. Preference will be for accelerators and more so for Machine Learning accelerators. text/html 2019-01-20T01:47:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.eecg.toronto.edu/~moshovos/000/doku.php?id=wiki:aca2019:sscompiler&rev=1547948839&do=diff Installing the Simplescalar compiler toolchain Get the precompiled binaries ssgcc.tbz from here: SS Toolchains.
