The system includes a unit for executing in a repetitive manner an instruction sequence within the instruction sequence. A program counter (74) gives the incremented number of the next instruction. A program address start register (76) records the number of the present instruction. A repeat counter (70), initialised with repeat number at execution of first instruction, decrements, stopping sequence at zero.Depending on the number of pipeline levels, of the last instructions contains an end of loop code which determines when the contents of the program address start register is loaded into the program counter, if not at zero.
