a simple 8086 simulator made in c++ it supports basic instructions like moving data in and out of memory and basic arithmetic operations like add , sub , mul and div.
currently it supports writing 8 bit and 16 bit data to memory and in between registers
MOV <REG,REG> moving data between registers
MOV ax,bx
MOV ds,ax
MOV ah,alMOV <MEMORY,REG> moving data between mem and registers
MOV [offset],reg(8bit)
MOV ah,[0043]
MOV [0323],ch
MOV <REG,immediate data> moving immediate data into registers
MOV AX,43
MOV ch,12
Note: please avoid data overflow as flag register are not currently supported. Due to which wrong results might be produced and you will have no way of knowing.
ADD AL,AH
ADD AX,06
ADD AH,BHSUB AH,BH
SUB AX,06
SUB AH,BHMUL AH,BH
MUL AX,06DIV AH,BL note div operations currently dont support reading data from memory
git clone https://github.com/7HAVEN/8086_simulator.git --recursive
cd 8086_simulator
mkdir build
cd build
cmake -- build .
./simulatorgit clone https://github.com/7HAVEN/8086_simulator.git --recursive
cd 8086_simulatorThen open the project in visual studio and then select cmake file as starting point and click run
Note: you must have cmake and Linux building tools in visual studio
the ui is made in imgui
pls dont read the code base its bad for your mental health i dont know how i managed to write such bad code its abysmal and doesn't follow any particular style and severe lack of comments is also a big problem but they dont teach us good coding practices in the university. and this thing doesn't support hex data so this is not an exact way how 8086 will behave therefor your results may vary i made this as university project and i passed the examination so i dont wanna fix any of these major issues for now and if you wanna use it feel free to clone the repo and add on this project.
