===Barrel Shifter===
The ARM can add a bit shift or rotate to one of its operands at no additional cost to execution time or bytecode. If the operand being shifted is a register, the value of that register is not actually changed. The shift or rotate only applies during that instruction.
<lang ARM Assembly>add r0,r0,r1 lsl 2 ;shift r1 left 2 bits, add r0 to r1, store the result in r0. r1 is unchanged after this instruction</lang>
