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. I'm 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.

![MPU 7 - 4 Function Calculator [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
Here the MPU 7 is allows the user to type in a number or an operator (+ - * /) followed by a number.
If a number is entered without an operator, then the accumulator is set to that number. Otherwise if an operator and number is given, it will perform that operator with that number on the value previously in the accumulator.
After each operation it prints out the resulting value to the display.
The program only supports integers from 0 to 99 - so no negative numbers or non-integers. The program could be rewritten to support these and add more than just 4 functions, but there would be almost no point.
The keyboard has a target block for each key and I throw a snowball at it to activate it. Annoyingly replay mod doesnt record the players hand, so you cannot see me holding and throwing snowballs at it in the video.
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.

![MPU 7 Pong (zero player) [ 2 Hz Minecraft Redstone CPU ]
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.
