Yeah, anything that fits into memory, which on that FPGA is very limited. It was built for fun rather than production.

This is just RV32I-ZMMUL not a custom architecture, bt if you do want to see something from scratch, without any premade ISA or anything, here is an NPU I built: https://www.armaangomes.com/blogs/kernn/

We hope to tape it out, along with an NPU and GPU once we raise $10k. Though first we have to find $10k :(

I'm kinda lazy lol. We are also implementing out-of-order rn, so we want to get a really solid rv32i setup going before adding multiplication, floating point, vector, etc.
