MISC (Minimal Instruction Set Computing) is a simple project simply for the enjoyment of computer science! Its a light CPU Emulator of my own architecture "very" lightly based on RISC. It is in very ealy stages of development so bare with me as I am only a Beginner/Intermediate programmer :).
MISC Emulator was also designed to be very configurable! Edit "config.conf" to configure the program :D.
I hope you enjoy this project and feel free to collaberate and share your creations!

| Config | Discription |
|---|---|
Bits |
How many bits the binaries will be written and read in |
Rows |
How many rows the RAM has |
Registers |
How many Registers will be added after the 4 Manditory Registers |
Display_size |
How big the display will be. Must be seperated by x eg. 32x32. |
The size of the display will effect the size of the memory. Its memory is appended strait on top of the RAM.
Formula:
| F = New Rows, R = Rows, X = Display X, Y = Display Y, B = Bits. |
