Converting very simple ARM instructions to binary/hex

WebData processing instructions mostly use one destination register and two source operands. The general format can be considered to be the instruction, followed by the operands, as follows: Instruction Rd, Rn, Operand2 The second operand might be a … WebUse of r15. If you use r15 as Rn, the value used is the address of the instruction plus 8. If you use r15 as Rd: Execution branches to the address corresponding to the result. If you use the S suffix, the SPSR of the current mode is copied to the CPSR.

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 ...
