When writing parallel instructions, the B-field instruction is written first, followed by the A-field
instruction. A sample parallel processing program using DSP instructions is shown in figure 3.6.
Parallel processing only instructions in the A field (without those in the B field) can be executed
(transferring data in parallel without DSP data operation instructions)
