6.3 Functional Unit Hazards
6-20
If you wish to optimize your instruction pipeline, consider the instructions that
are executed on each unit. Sources and destinations are read and written dif-
ferently for each instruction. If you analyze these differences, you can make
further optimization improvements by considering what happens during the
execution phases of instructions that use the same functional unit in each exe-
cution packet.
The following sections provide information about what happens during each
execute phase of the instructions within a category for each of the functional
units.
