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

1. 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.
2. Second assignment is jumping from real mode to protected mode and from there coming back.
3. Third assignment is printing transpose of matrix using mmx registers

1. First one must have qemu installed on machine with nasm. Set up the working environment.

2. To run part 1.a use following commands in shell:

   nasm -fbin printchar.asm -o printchar.bin
   qemu-system-i386 printchar.bin

3. 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

4. To run part part 2 use following commands in shell:

   nasm -fbin modejump.asm -o modejump.bin
   qemu-system-i386 modejump.bin

5. 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
