Can RVX be downsized?

Hi,

I've hardwired 0 to interrupt inputs, however the logic didn't get much smaller.

Hi @MrJake222, the interrupt handling logic comprises a small part of RVX. If you want to make RVX smaller, you can downsize the register file to 16 registers, effectively creating a RV32E implementation. This will reduce significantly the logic used for decoding the register file addresses.
