# The "Drop" ASIC

ASIC audio visual demo in less than 4000 Logic Gates.

No CPU, no GPU, no memory. Racing the beam straight to VGA 640x480.

Entry to Tiny Tapeout [Demoscene 2024 September](https://tinytapeout.com/competitions/demoscene/) competition. Taped out on [SKY130](https://github.com/rejunity/tt08-vga-drop/tree/sky130), [IHP130](https://github.com/rejunity/tt08-vga-drop/tree/ihp130) and *coming soon* [GF180](https://github.com/rejunity/tt08-vga-drop/tree/ttgf0p2) process.
