1) Add IRC channel to README 2) What if add some per-thread single-instruction buffer. Will pipeline can stall one cycle instead two. E.g. when register dependency. If I understood pipeline right.

  1. Yeah, I've thought about adding an IRC channel, but I only have a laptop, so I'd miss messages when offline. I've looked at some other chat services, but haven't found one that works great yet.
  2. There is an instruction buffer for each thread that can buffer up to 8 instructions: https://github.com/jbush001/NyuziProcessor/blob/31f74e43a785fa66d244f1e9744ca0ca9b8a1fad/hardware/core/thread_select_stage.sv#L123 Or were you proposing putting a FIFO somewhere else?
