ARM processor disassembler and emulator

General information for the business: N/A
Description of requirements/functionality: The task is written in C language and it's composed of two parts:
the first one should result in the development of a computer program which has the ability to fetch, decode and display the instructions within the provided instruction set. (Instruction Decoding and Disassembling )

The program should output something similar to the following.

Op-Code Assembly Mnemonic

----------------------------------

E3 A0 00 01 MOV r0,#1

E3 A0 10 02 MOV r1,#2

E0 80 20 01 ADD r2,r0,r1

E2 82 20 05 ADD r2,r2,#5

The second is Besic Emulation: as displaying each Assembly language instruction it should also emulate the behaviour of these. i.e. implement a basic CPU emulator. For this requirement only the basic ALU type instructions need to be supported, e.g. ADD, SUB, CMP, MOV.

Op-Code Assembly Mnemonic

----------------------------------

E3 A0 00 01 MOV r0,#1

R0: 00000001 R1: 00000000 r2: 00000000 r3: 00000000

R4: 00000000 R5: 00000000 r6: 00000000 r7: 00000000

R8: 00000000 R9: 00000000 r10:00000000 r11:00000000

R12:00000000 R13:00010000 r14:00000000 r15:00000104

Press for next instruction.


Extra notes: I have already started a good part of the first task.
