r/RISCV

Although the designer mentioned it's for educational purposes, why did he simplify stuff so much.

https://github.com/Grubre/smol-gpu

What are the reasons behind these simplifications:

1. Sequential warp scheduling

2. No warp-level parallelism within a core

3. No cache hierarchy

4. Separated program and data memory

5. No shared memory / scratchpad

6. No barrier / synchronization primitives

7. No reconvergence stack in hardware

and many more....

Is there any reasoning behind these simplifications?

I have also checked the RTL, there were few cases of possible race conditions. Is this repo even a legit baseline to make an advanced gpu on top of it?
