QT stands for QuickThreads, and in some cases is a massive speedimprovement. There was a technical paper on this back in the 94 called "Toolsand Techniques for Building Fast Portable Thread Packages". On an x86-architecture this speeds up SystemC by a factor of 40 (LinuxUbuntu). And I believe it will increase the arm speed by at least 500% for myuse case. Since the content switch isn’t that big for the arm having lessregisters to save compared to the x86. So QT should always be considered if available, but somehow it seems to passinto oblivion.

I can tell you're not referring to the widget toolkit. Also, I believe Guile uses pthreads on most platforms, so if you're running Linux on ARM (which is the common case on ARM nowadays, I think), you should have threads. Unless you want userspace threads.

Do youknow what the status of this port was? Did it work? I would like to add a QTfor ARM into the SystemC Open Source Project and I’m looking for a goodstarting point. ManyThanks in advance eactor
