Finally putting the UI to good use.
The program is quite slow and it adds an extra underscore to the end of the word but at least it works.
MPU6.0 Specs:
5 tick clock speed (0.5 seconds)
4 stage pipe (with dual instruction fetching to speed up conditional instructions)
8 bit word length
uses a custom version of VLIW arch
10 general purpose registers
32 bytes of RAM
128 word instruction ROM (split into 2 lots of 64 for dual fetching)
8 bit hardware multiplier
32 bit BCD converter
16x8 Pixel Display

The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 6x speed and the carpet mod tick speed is set to 2 times speed.
In this program the ball bounces around the screen while a non-player controlled paddle follows it.
Since it took about 9 seconds per frame, you wouldnt want to play this in real time lol.

This program simply prints text on the screen which is stored in the external ROM. This was done to test the external ROM to make sure it works.
This video has not been sped up but the tick speed has been set to 18 times speed. (so a net speed up of 18 times)

![3D Rotating Cube !! [ MPU 8 | 3.3 Hz Minecraft Redstone CPU ]](https://i.ytimg.com/vi/epuTvLgKYbE/mqdefault.jpg "3D Rotating Cube !! [ MPU 8 | 3.3 Hz Minecraft Redstone CPU ]
The MPU 8 is my latest and fastest Minecraft Redstone CPU.
Here the MPU 8 is rendering a 3D cube and rotating it.
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 cube 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 cube 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).

The MPU 8 is my latest and fastest Minecraft Redstone CPU.
Here the MPU 8 is running a FizzBuzz program.
Where for each value:
if the value is divisible by 3 it prints Fizz,
else if the value is divisible by 5 it prints Buzz,
else if its divisible by both 3 and 5 it prints FizzBuzz,
else it prints the value itself in base 10.
This video has been sped up 2 times and the tick speed has been set to 10 times speed. (so a net speed up of 20 times)
This program took 732 cycles to run (12 minutes and 12 seconds at default Minecraft speed).

The MPU 7 is my latest and fastest Minecraft redstone CPU.
To get the Fibonacci sequence, you simply add the previous 2 numbers together to calculate the next number - starting with 0 and 1.
The MPU 7 can calculate the next 16 bit number every 2 clock cycles (10 ticks or 1 second), if you ignoring converting the values to BCD and printing them to the display.
The video has been sped up to 2 times speed to make it less boring to watch and the tick rate has been sped up by carpet mod meaning it is running as fast as it can on my IRL computer.
