LDM
Example 3
In this third example, the following code sequence is executed:
LDM R12,{R1-R3}
ADD R2, R2, R1
The LDM takes three cycles to execute in the memory stage of the pipeline. The ADD
is therefore delayed until the LDM begins its final memory fetch. The behavior of both
the instruction and data memory interface are shown in Figure 7-3.
