3.4 Independent Execution Units
MPC555
USER’S MANUAL
The PowerPC architecture supports independent floating-point, integer, load/store,
and branch processing execution units, making it possible to implement advanced fea-
tures such as look-ahead operations. For example, since branch instructions do not
depend on GPRs, branches can often be resolved early, eliminating stalls caused by
taken branches.
