Jump Instruction




Start:
mov %a1,0x61
add a1,a2
jmp Start

The "Start:" is a label. "Start" refers to the Memory Address where the next instruction ("mov a1, 0x61") is at. On execution the CPU would move the value of 0x61 into a1 (which is an Address Register ), then add the contents a1 and a2, and on the jump instruction ("jmp Start") the CPU would go to the memory address "Start" where it would continue to execute the next instruction it found ("mov a1, 0x61").
