WebARM data processing instructions can be broken into four basic groups: Arithmetic (6) Logic (4) Comparison (4) Register transfer (2) We haven’t discussed the “S” field yet. If set, it tells the processor to retain some “state” after the instruction has executed. This “state” is in the form of 5-flags. Many instructions WebThe Program Counter (PC) is accessed as PC (or R15). It is incremented by the size of the instruction executed (which is always four bytes in ARM state). Branch instructions load the destination address into PC. You can also load the PC directly using data processing instructions. For example, to branch to the address in a general purpose ... iplayer blue planet
