No, we currently do not support configurable VLEN. VLEN in parameter.scala is a constant. |

I was testing some image processing kernels such as Gaussian blur with the frame size 1920x1080 as usual, thus vlen = 128 doesn't seem to be enough even with LMUL=4.
I tried to modify VLEN to 512 in parameter.scala and make emu with MinimalConfig, but failed with several errors from the EXUs. It seems the EXUs are not well parameterized.
