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 7 Specs:
• No command blocks or pistons
• 2 Hz clock speed (5 ticks or 0.5 seconds per clock pulse)
• 5 stage waterfall pipeline (Fetch1 - Fetch2 - Decode - Execute - Writeback)
• 10 general purpose simulated dual read registers (with no read before write hazards because of the automatic forwarding)
• 8 bit word length
• 256 word instruction ROM x2
• 32 bit instruction length (that includes an 8 bit immediate value)
• VLIW architecture
• 32 bit hardware BCD converter
• 8 bit hardware multiplier
• 8 bit hardware divider
• 8 bit RNG
• 64x32 pixel display (1x1 pixels) which can be shifted upwards 8 pixels whenever needed
• 1 frame buffer
• Full qwerty keyboard with arrow keys and function keys for user input
• 128 bytes of main RAM
• 256 bytes of screen RAM
• Up to 128 I/O ports
• External 8 kiB paging ROM for storing large amounts of data (Like Bad Apple!!)
• 7 testable flags
• Full 7 bit character set (a custom one, so not ASCII) which uses 4x8 characters
• Can be started, stopped and reset from the UI
• Almost fully compatible with URCL

![MPU 8 Mandelbrot [ 3.3 Hz Minecraft Redstone CPU ]](https://i.ytimg.com/vi/ms2oz5P05CU/mqdefault.jpg "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).

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.
