Postscript is also literally just a text based programming language for drawing stuff. You can create loops and recursions and all kinds of crazy transformations with a few lines of code.

I guess maybe we have different requirements, but I built a similar controller using a 68HC05 when I was in college (yes I am that old) and it had plenty of cycles left to burn. This thing is nearly an order of magnitude faster than the microcontroller I used.

EDIT: I will grant you the I/O is pretty limited, but you could also offload some of the work to an external timer/accumulator

The original DOOM ran on a 80386 which was actually slower than or roughly equivalent to this controller. Recommended system specs were for a 486 though which was maybe 2-3x as fast.

A 32bit @24MHz CPU is extremely overpowered for those use cases.

Qi operates in the 87-205 KHz range. A power tool is several orders of magnitude slower.
