MISC

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!

Configuration

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.

Note

The size of the display will effect the size of the memory. Its memory is appended strait on top of the RAM.

Formula:

F = R + X * Y / B

F = New Rows, R = Rows, X = Display X, Y = Display Y, B = Bits.

Registers

Register	Discription	Binary Code

Notes

The amount of registers can be configured. Refer to config.conf.

Register "eax" is where results are stored.

Comment (#): Ignores everything after "#" on that line.
