If the result is 0, the follow- ing instruction, fetched during the current instruction execution, is discarded and a dummy cy- cle is replaced to get the proper instruction (2 cycles). Otherwise proceed with the next instruction (1 cycle).

If the result is 0, the next in- struction is skipped and the result is stored in the accumulator. The data memory remains un- changed. If the result is 0, the following instruction, fetched during the current instruction execution, is discarded and a dummy cycle is replaced to get the proper instruction (2 cycles). Otherwise proceed with the next instruction (1 cycle).
