PP opcode formats
A PP instruction uses a 64-bit opcode. The opcode is divided essentially into a data unit portion and a parallel
transfer portion. There are five data unit opcode formats comprising bits 38–63 of the opcode. Bits 0–38 of the
opcode specify one of 10 parallel transfer formats. An alphabetical list of the mnemonics used in Figure 45 for
the data unit and parallel transfer portions of the opcode are shown in Table 12 and Table 13, respectively.
