tion stream. It shows the activity of the external bus, the bus controller, and
the sequencer.
The effect of instruction alignment on timing is illustrated b y t h e following
example. The assumptions referred to in 11.6 INSTRUCTION TIMING TABLES
apply. Both the data cache and instruction cache miss on all accesses.
The instruction stream is positioned with even alignment in 32-bit memory
as:
