Currently on it! I am currently deep into the vertex shader, writing the routines to transform the vertics in assembler. Object format and how the drawing pipeline is formated are already done! And welcome on the hardware train! Here you will see how software and hardware work together in "harmony"

I packed it full with a lot of new stuff i had to develop over time like the half precision FPU and the MMU. It also comes with 4-stage partial forwarding pipeline, interrupts with different priorities, timer, ring mode, a lot of MMU configurations, separate main memory/IO address space, ...

As a german bread enjoyer i can confirm: perfection

Btw. the ROB is messy but works quite well. But you can see here why implicit renaming designs weren't much of a thing and why explicit renaming is the name of the games today
