@ -24,8 +24,23 @@ 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 | | |
| Binary sequence | Instruction | Action |
| --------------- | -------------------- | ---------------------------------------- |
| 1110 | condition | always execute (unconditional) |
| 00 | -- | -- |
| 1 | immediate | value is in the last 8 bits |
| 1101 | opcode | `mov` : move the value |
| 0 | -- | -- |
| 0000 | -- | -- |
| 0111 | destination register | destinaation is 0111 which corresonds |
| to `r7` |
| 0000 | -- | -- |
| 00000100 | immediate value | the binary representation of decimal '4' |
- The blank values are also instruction points, they are just not used in this
instruction
- The instruction should run in all conditions not only under certain
circumstances
- The immediate bit (`1`) tells us
