3D Rotating Pyramid [ MPU 8 | 3.3 Hz Minecraft Redstone CPU ] @ModPunchtree

Uploaded July 2022 | Updated September 2026, 2 weeks ago

The MPU 8 is my latest and fastest Minecraft Redstone CPU.

Here the MPU 8 is rendering a 3D square based pyramid and rotating it.

This is using the exact same 3d renderer program as the one used for the 3D rotating cube. I have made this to show that it can render any small 3D shape fairly easily.

The matrix multiplications for calculating the rotation and rasterisation of the cube are all being calculated each frame by the CPU.

This is NOT a video and it does NOT use precalculated points - the positions of the points are ALL calculated on the CPU.

For trigonometry i simplified it a lot by assuming that Sin(x) = x and Cos(x) = 1 where x is a small angle, this gives an approximation that is good enough for a couple minutes.
In this program the pyramid becomes more distorted as time progresses due to the rounding errors building up from the division operations as well as the trigonometry assumption.
(this is why the pyramid looks quite twisted and stretched towards the end)

This video been sped up 8x and the tick speed has been set to 800 times speed (so a total speed up of 6400x).

$MPU 7 Recursive Fibonacci (B code) [ 2 Hz Minecraft Redstone CPU ] The MPU 7 is my latest and fastest Minecraft Redstone CPU. Here the MPU 7 is running recursive Fibonacci written in B code that has been compiled to URCL code using the B compiler I wrote. This program does not use memorisation and it took approximately 1.5 hours to calculate all the way up to fib(8). B code for recursive Fibonacci: auto fib(auto x) { if (x ＜ 2) { return x; } return fib(x - 1) + fib(x - 2); } auto x = -1; while (1) { x += 1; asm { OUT %TEXT n; OUT %TEXT f; OUT %TEXT i; OUT %TEXT b; OUT %TEXT (; OUT %TEXT x; OUT %TEXT ); } auto answer = fib(x); asm { OUT %NUMB answer; } } Anyone who wants to run code on the MPU 7 can feel free to send me URCL programs (or B code!) and I can attempt to run them. The MPU 7 is capable of doing up to fib(13) = 233 but it would take several days to run. To run URCL code, I translate the URCL code line by line into MPU 7 assembly using a dictionary of translations in a Python program I wrote. Then I write the translated MPU 7 assembly into the instruction ROM and run it. It really is that simple.

MPU 7 - 32 bit Fibonacci [ 2 Hz Minecraft Redstone CPU ]

$MPU 8 Mandelbrot [ 3.3 Hz Minecraft Redstone CPU ] The MPU 8 is my latest and fastest Minecraft Redstone CPU. Here the MPU 8 is generating the mandelbrot fractal at 64x64 pixel resolution with 20 iterations per pixel. For the calculations I used 2.6 fixed point numbers and a look-up table in the RAM which stored the initial values for each coordinate. This video has been sped up 8 times and the tick speed has been set to 1400 times speed. (so a net speed up of 11200 times) This program took 2375726 cycles to run (198 hours at default Minecraft speed).
