8.1.5 Instruction Stream Timing Examples
A programming example allows a more detailed examination of these effects. The effect of
instruction execution overlap on instruction timing is illustrated by the following example
instruction stream.
Example 1
For the first example, the assumptions are:
For example 1, the instruction stream is positioned in 32-bit memory as follows:
Figure 8-3 shows processor activity on the first example instruction stream. It shows the
activity of the external bus, the bus controller, the sequencer, and the attributed instruction
execution time.
8-4
1. The data bus is 32 bits,
2. The first instruction is prefetched from an odd-word address,
3. Memory access occurs with no wait states, and
4. The instruction cache is disabled.
