The last month of my life: BreakingTTAPs This is a custom transport-triggered, 32 bit processor that will be fabricated by GlobalFoundries on their 180nm process (via of wafer.space) I'll make a video at some point, but some high level details here:

I did manage to sneak in two small silicon art logos. Wish I had more time to put more on the chip but oh well!

Clock speed is sorta up in the air. Still optimizing, but simulations say it should hit ~20MHz in all "process corners" (i.e. if the fab makes slow transistors and the chip is 125C hot). Probably faster in nominal case but we'll see

Instruction set is pretty standard set of ALU, LSU, comparisons, branching, bit manip, etc. But I snuck in a few fun extras like a pseudorandom number generator, tanh and multiply-and-accumulate to try some light ML inference (rough plan is reservoir computing)
