Section 4 Instruction Features
Data transfers are executed in the MA stage of the pipeline while DSP operations are executed in
the DSP stage. Since the next data store instruction starts before the data operation instruction has
finished, a stall cycle is inserted when the store instruction comes on the instruction line after the
data operation instruction. This overhead cycle can be avoided by adding one instruction between
the data operation instruction and the data transfer instruction. Figure 4.22 shows an example.
