Introduction
1.3 Block, core, and functional diagrams
The ARM7TDMI processor architecture, core, and functional diagrams are illustrated
in the following figures:
Figure 1-2 shows a block diagram of the ARM7TDMI processor components and
major signal paths
Figure 1-3 on page 1-8 shows the main processor (this is the logic at the core of
the ARM7TDMI
Figure 1-4 on page 1-9 shows the major signal paths for the ARM7TDMI
processor.
