JUMP CALL
The DSP can be executed with single cycle instruction using the independent data memory
and program memory buses offered by the modified Harvard architecture and pipeline
instruction. This method provides overlapping of instruction fetch and execution cycles.
Figure 27 illustrates the execution sequence. The first instruction takes two clock cycles to
execute; subsequent executions occur in a single cycle. All instruction fetch cycles have
the same machine timing regardless of whether external or internal memory is used.
Because the DSP contains a two-level pipeline, the JUMP and CALL instructions do not
disrupt the execution process
