4 Registers (0-4)
2 DISCKS and 1 BIOS

Usage

I. Download Repository From Release Branch.
II. Download Java Java
III. Go to APP Folder
IV. Run logisim-win-2.7.1.exe
V. Open File and load CPU.circ
VI. Load Images from OS Folder to Bios and Disk

Asembler Operations codes

Code	What do	Structure	!
mmu	Set MMU locations on disk to jump there for example when you use loop.	mmu (Place on Disk in Hex)	Register 1 = MMU ID Register 2 = Disk Location !Location need by increment by one!
gto	Fill Spaces betwaen MMU aplications	gto "Place on Disck in Hex"
jmp	Jump to MMU location.	jmp	Register 3 = Disk Register 1 = MMU ID !Compare need be set on true condition!
var	Set Data on Register.	var (Register) "Data"
pri	Print text in terminal.	pri "Text"
nel	Go to next line.	nel
prr	Copy Data from one Register and paste data in another.	prr (Register) (Register)
out	Display Data from Register.	out (Register)
get	Get Data From Input and save in register.	get (Register)
sme	Save data from Register in RAM.	sme (Register)	RAM Location = Register 4
gme	Get Data From RAM and save in Register.	gme (Register)	RAM Location = Register 4
com	Compare two datas.	com	A = Register 1 B = Register 2 OP = Register 3 Avaible Operations: 0 -> > 1 -> = 2 -> < 3 -> <= 4 -> != 5 -> >= 6 -> True 7 -> False
alu	Make ALU operations.	alu	OP = Register 0 A = Register 1 B = Register 2 Result = Register 3
wai	Wait for input.	wai
dsc	Go to Disk from Register.	dsc (Register)	You need set Jump before you go to Disck
sav	Save data on disck.	sav	Disck = Register 3 Data = Register 2 Location = Register 1
end	End Program	end

OP Table

DESCRIPTION	OP	R	R	More Info
NULL	0			Do nothing
R -> M	1	R		Save in RAM R4=location
M -> R	2	R		Get from RAM R4=location
JMP	3	R		R3=Disck to jmp R1 mmu loation Need compart 1
ALU	4			OP = Register 0 A = Register 1 B = Register 2 Result = Register 3
GET	5	R		get data to register
OUT	6	R		out data from register and display on tty
R -> R	7	R(from)	R(to)	copy from register to register
R -> Rom	8			Save data on disck R3=Disck R2=Data R1=location
NULL	9
WAIT	A			Wait for input
COMPARE	B			Compart A = Register 1 B = Register 2 OP = Register 3 Operations: 0 - > 1 -> = 2 -> < 3 -> <= 4 -> != 5 -> >= 6 -> True 7 -> False
MMU	C			R1=location R2=content Need by set before jmp location +1
Change Disk	D	R		go to dick from register need set location to jmp before
D - > R	E	R	D	Set register
STOP	F			end program
