Parallel Processing Instructions: The parallel processing instructions allow for more efficient
execution of digital signal processing using the DSP unit. They are 32 bit length, allowing
simultaneously in parallel four processes, ALU operations, multiplications or 2 data transfers.
The parallel processing instructions are divided into A fields and B fields. The A field defines data
transfer instructions; the B field defines ALU operation instructions and multiplication
instructions. These instructions can be defined independently, the processes can be independent,
and furthermore, they can be executed simultaneously in parallel. Table 2.17 indicates the A field
parallel data transfer instructions, and table 2.18 indicates the B field ALU operation instructions
and multiplication instructions.
