95 / 935 page ![]() Section 2 CPU Rev. 2.00 Mar 09, 2006 page 69 of 906 REJ09B0292-0200 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. A fields instruction is the same as double data transfers in table 2.15.
