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/

When you say "can upload any model to it" are you talking LLM models? Surely there is a limit eg. parameters

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