Title: CHUNGUS 2 - A very powerful 1Hz Minecraft CPU
Post by: Stefan on December 22, 2021, 11:24:04 AM
CHUNGUS 2: Electric Boogaloo - A Minecraft CPU capable of running Tetris, snake, connect 4, graph rendering... and more! (

CHUNGUS stands for Computational Humongous Unconventional Number and Graphics Unit by Sammyuri.
The CPU is also very large.
In order to achieve a 10 tick clock speed despite its enormous size, the CPU makes use of techniques such as an instruction pipeline, automatic data cache and simple branch prediction.


CPU specs
- 8 bit data, 16 bit fixed size instruction length
- 1Hz clock speed, 4 stage instruction pipeline (fetch - decode - execute - writeback)
- 64 byte automatic 8-way associative data cache and 256 bytes RAM
- Up to 256 addressable I/O ports
- 7 general purpose registers
- Over 40 ALU functions, including a hardware barrel shifter, multiplier, divider and square rooter
- 32x128 byte program pages for a total of 4KiB program storage

Other hardware used in video
- 32x32 buffered pixel screen, draw and erase pixels, rectangles, up to 8 4x4 sprites
- 12x2 character ASCII text display
- 2x 8-bit integer display (signed or unsigned)
- 8-input NES-style controller
- 3 bit pseudo-RNG
