Instruction behaviour
a = a * b
MUL r0, r1
Most instructions occupy 2 bytes of memory
When executed, complete in a fixed time
The instructions operate on 32-bit data values
– Data processing (e.g. add, shift, logical OR) take 1 cycle
– Data transfers (e.g. load, store) take 2 cycles
– Branches, when taken, take 3 cycles
– Processor registers and ALU are 32-bit wide!
