...ommunications in Tokyo. They put forward new and interesting micro-architectural ideas along with the new ISA ideas, which I think has limited the impact of their work, because doing a credible design and evaluation of entirely new micro- architectures is so hard. See, e.g.: http://bit.ly/iStSmS [ACM Digital Library] The angle I'd like to explore is combining a queue-based ISA with a more conventional micro-architecture. To the first order, all you have to do in the micro-architecture is replace the architectural register to physical register renaming with a queue position to...

I am interested in working on a little architecture project that involves modifying an ISA in some non-trivial ways and seeing what impact it has on instruction frequencies (and other such metrics). Clearly I'll need to hack on a compiler backend, and I thought that LLVM might be a good choice since among mature compiler infrastructures it's fairly young and presumably
