8.2

Parallel-Executability

Instructions are categorized into six groups according to the internal function blocks used, as
shown in table 8.1. Table 8.2 shows the parallel-executability of pairs of instructions in terms of
groups. For example, ADD in the EX group and BRA in the BR group can be executed in parallel.
