This repository contains all the assignments related to Advanced microprocessors x86 and mmx controllers.

What's inside?

a) First assignment is related to printing the keypresses on qemu screen by writing in video memory using interrupt
b) Second part is related to printing without using interrupt.
Second assignment is jumping from real mode to protected mode and from there coming back.
Third assignment is printing transpose of matrix using mmx registers

First one must have qemu installed on machine with nasm. Set up the working environment.
To run part 1.a use following commands in shell:

nasm -fbin printchar.asm -o printchar.bin
qemu-system-i386 printchar.bin
To run part 1.b use following commands in shell:

nasm -fbin bootloader.asm -o bootloader.bin
nasm -fbin realmode.asm -o realmode.bin
cat bootloader.bin realmode.bin > result.bin
qemu-system-i386 result.bin
To run part part 2 use following commands in shell:

nasm -fbin modejump.asm -o modejump.bin
qemu-system-i386 modejump.bin
To run part 3 use following commands in shell:

nasm -fbin bootloader.asm -o bootloader.bin
nasm -fbin transpose_of_matrix.asm -o transpose.bin
cat bootloader.bin transpose.bin > result.bin
qemu-system-i386 result.bin
