          1824         The ARM instruction set
        ❏  ARM instructions fall into three categories:
   The Universityof Manchester
           ❍data processing instructions
              –  operate on values in registers
           ❍data transfer instructions
              – move values between memory and registers
           ❍control flow instructions
              –  change the program counter (PC)

          1824    Data processing instructions
        ❏ All operands are 32-bits wide and either:
   The Universityof Manchester
           ❍come from registers, or
           ❍are literals (‘immediate’ values) specified in the instruction
        ❏ The result, if any, is 32-bits wide and goes into a
           register
           ❍except long multiplies generate 64-bit results
        ❏ All operand and result registers are independently
           specified
