Okay, so here we have our ML605 FPGA board with our rVEX bitstream
already programmed in. Now, I will give the command to start
loading Linux into the board. First, we’ll load the Linux executable and the root filesystem. Once that’s done, we’ll see Linux booting on the upper left screen. So now Linux is booting and now it’s done. I can execute the Mandelbrot program and then on the right we see the program executing in 8-way. Now, I change it to 4-way and to 2-way and we can see the speed of execution
changing. The colors indicate which issue width it’s running in so if I change it back to 4–issue than the bar will turn green. When it’s red it is running in 2-issue and when it’s blue it is running in 8-issue mode. So now, the program has terminated
correctly and then I can execute a different program. This time a ray tracer and you can see it executing in 4-issue mode and I can change it to 2-issue mode and it slows down. Or, I can change it to 8-issue and it speeds back up.

    How is the core design licensed? on the tu delft webpage it says open-source, but is that something like gpl or bsd?
