![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 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

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 calculating Pi using the BBP formula with 16 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 964 cycles (8 minutes and 2 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.
