x86-64 CPU Architecture Simulation
Getting Started
Prerequisites
Make sure you have installed all of the following prerequisites on your machine:
flex>=2.6.4bison>=3.3.2cmake>=3.8- a
C++17compilergcc, g++, ...
Build
# make sure to build in a seperate folder
mkdir build
cd build
cmake ..
makeFor Debian based operating systems you can just use this:
sudo apt-get install flex bison cmake g++ git && git clone https://github.com/AnisBdz/CPU && cd CPU && mkdir build && cd build && cmake .. && makeUsage
Intel's x86-64 Architecture Simulation
Usage:
./app [OPTION...] filename
-f, --filename arg Input filename
-i, --interactive Enable interactive execution
-s, --speed arg Execution speed (instruction per minute) (default: 100)
-h, --help Print usage
Examples
examples/add_loop.asm
; example program that calculates the sum of two integer vectors
; it showcases data declaration, function calls and some instructions
section .data
x dd 1, 2, 3, 4
y dd 5, 6, 7, 8
z dd 0, 0, 0, 0
section .text
; the execution starts here
call main
; you should always end your program with the halt instruction
; or else you program will result in a segmentation falt
hlt
main:
; enter
push ebp
mov ebp, esp
mov ecx, 0
mov esi, x
mov edi, y
mov edx, z
loop:
mov eax, [esi + ecx * 4]
add eax, [edi + ecx * 4]
mov [edx + ecx * 4], eax
add ecx, 1
cmp ecx, 4
jne loop
; leave
mov esp, ebp
pop ebp
retCheck the examples folder for more... examples, ya know!
Unit Tests
This project uses Catch2.
The tests are available in the tests folder.
After building the project, a unit_tests executable will be created.
$ ./unit_tests
===============================================================================
All tests passed (18 assertions in 3 test cases)
