Machine code
No matter how a program was originally written, it eventually needs to execute on a CPU_architecture as a series of machine language instructions.
Example machine instruction
The following machine instruction is an instruction that would be understood by
an Instruction_set_architectures. It moves the number 4 into the
r7 register:
11100011101000000111000000000100
This 32bit line of binary has a series of instructions embedded within it. We partition each part of the sequence below, from left to right, mapping it to the instruction:
| Binary sequence | Instruction | Action |
|---|---|---|
| 1110 | ||
| 00 | ||
| 1101 |
