![MPU 8 Ball Physics Simulation [ 3.3 Hz Minecraft Redstone CPU ] @ModPunchtree](https://i.ytimg.com/vi/YyEB-IWUM04/maxresdefault.jpg)
Uploaded July 2022 | Updated September 2026, 3 weeks ago
The MPU 8 is my latest and fastest 3.3 Hz Minecraft Redstone CPU.
This program is built upon the previous Amiga bouncing ball demo to add another smaller ball and simulate collisions between them.
It is far from perfect because the balls overlapped a lot more than I would like but it mostly works.
The large ball accelerates slower than the smaller ball in this simulation, to try and create the illusion that the larger ball is heavier than the smaller one.
The large ball is made of 8 software sprites and the small ball is made of 2 software sprites.
This video has not been sped up!
However the tick speed has been set to 600 times speed thanks to MCHPRS.

![MPU 7 - 32 bit BBP Pi [ 2 Hz Minecraft Redstone CPU ]](https://i.ytimg.com/vi/a0hSzy4FCJc/mqdefault.jpg "MPU 7 - 32 bit BBP Pi [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 64x speed and the carpet mod tick speed is set to 2 times speed.
Here the MPU 7 is calculating Pi using the BBP formula with 32 bit fixed point values. Then it converts this result into base 10 and prints it to the display.
The flashing horizontal line is the cursor. This just shows what area of the screen the MPU 7 is currently writing to.
This program took a total of 3755 cycles (31 minutes and 17.5 seconds) to run. This includes the time spend initialising the registers/ram and the time draw to the display.

![MPU 7 Gradient Line Drawer [ 2 Hz Minecraft Redstone CPU ]](https://i.ytimg.com/vi/b5EMtdrnv-0/mqdefault.jpg "MPU 7 Gradient Line Drawer [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 16x speed and the carpet mod tick speed is set to 2 times speed.
Here the MPU 7 is drawing a triangle using a line drawing algorithm that calculates the gradient of the line as a fixed point value. Then the coordinates of the line are found by incrementing the x coordinate and adding the gradient to the y coordinate.
The flashing horizontal line is the cursor. This just shows what area of the screen the MPU 7 is currently writing to.
The coordinates of the triangle are:
(20, 2)
(5, 9)
(25, 14)
This program took a total of 3145 cycles (26 minutes and 12.5 seconds) to run. This includes the time spend initialising the registers/ram and the time draw to the display.
In theory this algorithm should be faster than Bresenhams but surprisingly it ended up being slightly slower. Im guessing that the difference is mostly due to the program being less optimised meaning if this program was rewritten it may end up being faster.
