This shows fib(8) being calculated using a recursive fibonacci program which was written in B and then compiled to URCL which was then translated to MPU6 assembly.
This video is sped up 512 times as it took just under 40 minutes for this program to calculate fib(8).
The original program written in B was very simple and it does not feature memorization, as well as the compiler not optimising the code very well so this is why the program takes as long as it does.
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
10x5, 8 Segment Char Display (using the MPU-64 character set)

![MPU 7 - 32 bit Fibonacci [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 32x speed and the carpet mod tick speed is set to 2 times speed.
Here the MPU 7 is storing two 32 bit values (each taking 4 registers) and calculating the Fibonacci sequence using them. After calculating each value it converts the number to base 10 and prints it to the display.
When the value reaches the highest possible 32 bit Fibonacci number (2 970 215 073) then it halts the CPU.
The flashing horizontal line is the cursor. This just shows what area of the screen the MPU 7 is currently writing to.

![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).

![MPU 7 - 8 bit BBP [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 4x speed and the carpet mod tick speed is set to 2 times speed.
Here the MPU 7 calculates BBP Pi using 8 bit fixed point, then it converts it into decimal and prints it to the screen.
