USER’S MANUAL
branch has nine bits. This will yield a conditional branch displacement limit of two
Kbytes.
When a change of flow occurs, the sequencer of the PPC core will issue the new ad-
dress in compression mapped format. The address extractor unit of the BBC gener-
ates the direct branch address format to internal memory.
Indirect branches use the regular two pointer format described in the previous section.
